When pipetting precious reagents it is a significant advantage to reduce the waste or dead volume in the reservoir.  We have accomplished this with our autoclavable polypropylene reusable reservoirs (VP 530) by machining dimples in the bottom on 9 mm centers to conform to the 96 well pattern.  The reservoir conforms to SBS standard dimensions of 127.7 mm long 85.5 mm wide and with a 25.4 mm deep cavity and stands 32 mm tall.  The total capacity of the reservoir is 200 ml.  A significant advantage of polypropylene is it's resistance to most organic solvents.  For a complete list of solvent resistance follow this link.  For chemical resistance properties of Polypropylene and other commonly used plastics follow this link.

In addition to these reusable reservoirs we also offer disposable polypropylene reservoirs for those that prefer the convenience of disposables.  One of the differences between the disposable and reusable dimpled reservoirs is the height of the reservoirs.  This may be an issue depending the length of your pipet tips and clearance issues for the robot.

Dead volume and maximum volume of reagent reserviors.

VP 530A

One of the most significant advantages of our machined polypropylene reagent reservoirs is that we can machine control wells into the reservoir so you can have several different control reagents.  Control wells can be applied to any section of the reservoir on a custom basis.  The VP 530A reservoir at the right has 8 separate control wells.  The center control wells have a capacity of 2.5 ml each.  The top and bottom control wells have a capacity of 3.0 ml each.  The main reservoir has a capacity for 175 ml of reagent.  Note that the control wells in addition to the common reagent reservoir have dimples to minimized dead volume loss.

VP 530B

The VP 530B reservoir at the right features a main reservoir with a capacity for 175 ml of reagent and a single column control reservoir  with the ability to hold 20 mls.  Again both sections are dimpled to minimize dead volume loss.  The reagent reservoir conforms to SBS standard dimensions of 127.7 mm long 85.5 mm wide and with a 25.4 mm deep cavity and stands 32 mm tall.  The reservoirs are constructed of solvent resistant,  autoclaveable polypropylene.

VP 530C

The VP 530C Maximum Reagent Reservoir at the right was designed to hold the maximum volume a precious reagent with a minimum waste in the bottom of the reservoir.  The reservoir was also designed to fit on the deck of a Beckman FX robot using the standard Beckman plate holder and the longest Beckman pipet tips (reservoir depth = 37 mm).  We made the reservoir "oversized" on the top to increase the holding volume (700 ml) and undercut the bottom so it would fit in the standard 127.7 mm by 85.5 mm SBS foot print plate holders on the FX .  See undercut on the photo to the right (arrows).  Out side dimensions are 190.3 mm by 115.3 mm and 54.3 mm tall.

All of the reservoirs can be customized with inlet and outlet connectors.  The VP 530C to the right was customized with quick disconnect fittings that seal when disconnected.  The Inlet is place high in the reservoir wall and the outlet at the bottom of the reservoir to facilitate the exchange of reservoir liquids.

Dead volume and maximum volume of reagent reserviors.

VP 530D

The VP 530D reservoir at the right features a thicker wall (7 mm and 10 mm thick) so that walls come right down to the dimples thus leaving less space for reagent to puddle and be lost to the dead volume.  The reservoir has a capacity for 170 ml of reagent and a dead volume of 2.4 ml.   Again this plate is dimpled to minimize dead volume loss.  The outside of  the reagent reservoir conforms to SBS standard dimensions of 127.7 mm long 85.5 mm wide and with a 24 mm deep cavity and stands 32 mm tall.  The reservoirs are constructed of solvent resistant, autoclaveable polypropylene. 

VP 531

When pipetting precious reagents it is a significant advantage to reduce the waste or dead volume in the reservoir.  We have accomplished this with our autoclavable polypropylene reusable reservoirs by machining dimples in the bottom on 4.5 mm centers to conform to the 384 well pattern.  The VP 531 reservoir conforms to SBS standard dimensions of 127.7 mm long 85.5 mm wide and with a 25.4 mm deep cavity and stands 32 mm tall.  The total capacity of the reservoir is 200 ml. 

VP 531A

When pipetting reagents into assay plates with 96 or 384 well pipetting heads it is often useful to have multiple control reagents in separate compartments.  The difficulty is to make the separating walls thin enough they do not interfere with the pipet tips.  We have made several such reservoirs with very thin walls (1.38 mm thick) so the pipets can reach bottom of the reservoir.  This dimension allows pipet tips to be as large as 3.12 mm in diameter when they are 25.4 mm from the tip.   Most 384 pipet tips are only 2.5 mm in diameter at this distance from the tip.

We have also "dimpled" the bottom of the reservoir so the last dregs of an expensive reagent can be used.

VP

VP 531P-PEEK

The VP 531P-PEEK is a 384 style reagent reservoir with 24 small one column wide control wells in all columns. Each column has a "U" bottom and 19 mm deep, separating walls = 0.75 mm thick.  Reservoir dimensions are 127.7mm long 85.5mm and 32mm tall and made from autoclaveable PEEK.  

Dividing walls are 0.75 mm wide.  Check your pipet tip separation to see if it can accommodate the wall thickness.

The hydrophilic coating on these reservoirs maximizes the recovery of the reagents used in them.  The hydrophilic coating prevents droplet formation and causes the reagent to collect in the dimpled area.  We also facilitate this collection of reagent in the dimples by bringing the walls into the dimpled area and then rounding that corner to prevent loss of liquid in the corner.  The Polypropylene, Delrin and PTFE reservoirs described above all are hydrophobic and leave droplets of reagents in the flat areas and in the corners and therefore have larger "dead volumes". 

Another advantage of the aluminum reservoirs with control wells is that we can make the separating walls thinner with aluminum than with the plastics (Polypropylene, Delrin and PTFE) 0.7 mm thick versus 1.3 mm thick, thus eliminating potential problems with some brands of pipet tips hanging up on the separating walls when they near the bottom of the reservoir.

A third advantage of the hydrophilic coated aluminum reservoirs is that air bubbles are not trapped in the dimples in the bottom.  Just pour a little reagent in, swirl and the dimples fill with your liquid and air is not trapped in the dimple.  This is not the case with Polypropylene, Delrin and PTFE where the air in the dimples has to be removed (dislodged by pipet tip) or by centrifugation.

Our hydrophilic coating is not affected by 30% H2O2, salt, all acids except hydrofluoric acid, all bases, all polar and non-polar solvents, and potassium ferrocyanide. It also can be autoclaved and chemically sterilized.

The advantages of the coated aluminum are that it is possible to make the dividing walls much thinner (0.7 mm) out of aluminum than any of the plastics (1.3 mm).  This feature is important with wider pipet tips as the wide ones don't have enough clearance to straddle the plastic dividing walls when the tips are at the reservoir bottom.

The reagent reservoir conforms to SBS standard dimensions of 127.7 mm long 85.5 mm wide and with a 19 mm deep cavity and stands 32 mm tall.  The advantages of the coated aluminum are that it is possible to make the dividing walls much thinner (0.7 mm) out of aluminum than any of the plastics (1.3 mm).  This feature is important with wider pipet tips as the wide ones don't have enough clearance to straddle the plastic dividing walls.

The second advantage is the hydrophilic coating which prevents droplet formation and causes the reagent to collect in the dimpled area.  We also facilitate this collection of reagent in the dimples by bringing the walls into the dimpled area and then rounding that corner to prevent loss of liquid in the corner.

A third advantage is that hydrophilic coating prevents air bubbles being trapped in the dimples.

VP 531R-1AL

The VP 531R-1AL is a 384 style reagent reservoir with a single control section made from hydrophilic coated aluminum.  The control section is from I 23 to P 24.  The bottom of each section is dimpled in a 384 pattern.  The main chamber holds -- ml.    The control is dimpled in a 384 pattern and holds -- ml.  By dimpling the bottom of the reservoir, the last dregs of an expensive reagent can be used. 

The reagent reservoir conforms to SBS standard dimensions of 127.7 mm long 85.5 mm wide and with a 19 mm deep cavity and stands 32 mm tall.  The advantages of the coated aluminum are that it is possible to make the dividing walls much thinner (0.7 mm) out of aluminum than any of the plastics (1.3 mm).  This feature is important with wider pipet tips as the wide ones don't have enough clearance to straddle the dividing walls.

A third advantage is that hydrophilic coating prevents air bubbles being trapped in the dimples.

The bottom of the reservoir has registration holes drilled in it so that it can be placed on a VP 744 Heater/Chiller block to control the temperature of the reagents.  Because the VP 744 registers to robotic deck tiles the reagent reservoir will also be registered to the robot's deck position.

VP 531R-2AL

The VP 531R-2AL is a 384 style reagent reservoir with two control sections made from hydrophilic coated aluminum.  The first control section is from I 23 to L 24, the second is from M 23 to P 24.  The bottom of each section is dimpled in a 384 pattern.  The main chamber holds -- ml.    Each control chamber is dimpled in a 384 pattern and holds -- ml.  By dimpling the bottom of the reservoir, the last dregs of an expensive reagent can be used.

Maximum Reagent Reservoir at the right is made from hydrophilic coated aluminum.  It was designed to hold the maximum volume a precious reagent in the main reservoir (175ml) and also in the 16 control chambers.   The reservoir was also designed to fit on the deck of a Beckman FX robot using the standard Beckman plate holder and the longest Beckman pipet tips (reservoir depth = 23.4 mm).  We made the reservoir "oversized" on the top to increase the holding volume of the reagent chambers (4ml) and undercut the bottom so it would fit in the standard 127.7 mm by 85.5 mm SBS foot print plate holders on the FX .    Out side dimensions are 161 mm by 85.5 mm and 25.4 mm tall. The  bottom of the VP 531S-AL is not dimpled.  It can be used with both 96 and 384 pipet heads.

The advantages of the coated aluminum are that it is possible to make the dividing walls much thinner (0.7 mm) out of aluminum than any of the plastics (1.3 mm).  This feature is important with wider pipet tips as the wide ones don't have enough clearance to straddle the plastic dividing walls.

VP 532-AL

The VP 532-AL is a 1536 reagent reservoir made with hydrophilic coated aluminum.  1.5 mm diameter dimpled depressions with rounded inside corners to dimples.

The reagent reservoir conforms to SBS standard dimensions of 127.7 mm long 85.5 mm wide and with a 5 mm deep cavity and stands 10 mm tall.

VP 532-ALA

The VP 532-ALA is a 1536 reagent reservoir made with hydrophilic coated aluminum.  1.5 mm diameter dimpled depressions with rounded inside corners to dimples and 8 control wells at each edge.

The reagent reservoir conforms to SBS standard dimensions of 127.7 mm long 85.5 mm wide and with a 5 mm deep cavity and stands 10 mm tall.

The VP 533-AL is designed to be used with Deerac Fluidics liquid handlers.  Our special hydrophilic coating has the advantage of preventing droplet formation and causes the reagent to collect in the "V" bottom.  With very precious reagents being conserved it doesn't take long for these reservoirs to pay for themselves.

Our reagent reservoirs with baffles are used with robot systems that move the reservoir to a stationary pipetting head or pin tool such as the Apricot, Cybio, Matrix, and Tomtec.  The baffles are very effective in dampening wave action.  The volume of liquid in the reservoir can be maintained at maximum height without fear it will be spilled over the edge of the plate upon movement.

VP 540

The VP 540 is constructed of autoclaveable polypropylene to fit into the SBS standard foot print with dimensions of 127 mm long, 85 mm wide and 32 mm tall with a cavity 25 mm deep.  The reservoir will hold 215 ml of reagent.  The sides of reservoir have 13 notches on each side to locate 13 VP 540F wave dampening baffles.  Each baffle is constructed of autoclaveable epoxy composite G10 and has a semicircle machined in the bottom to allow fluid flow between the chambers.   Baffles must be ordered seperately. 

These reservoirs are also used in our wash and blot system for cleaning pin tools.

VP 540L

The VP 540L is constructed of autoclaveable polypropylene to fit into the SBS standard foot print with dimensions of 127 mm long, 85 mm wide and 32 mm tall with a cavity 25 mm deep.  The reservoir will hold 215 ml of wash fluid.  This reservoir was designed for applications on carousel robotic decks where rotational movement of the deck will set up a wave motion that will cause the reservoir contents to be "sloshed" out of the reservoir. The VP 540L has notches machined into the ends of the reservoir so the longer VP 540LF baffles can be placed parallel and thus prevent sloshing.

The VP 540LF Baffles are constructed using the autoclaveable epoxy composite G10.

VP 540PCB

The VP 540PCB is constructed of solvent resistant PTFE to fit into the Cybi Well Robot plate holders. The dimensions are 140 mm long, 102.3 mm wide and 32 mm tall with a cavity 26 mm deep.  The reservoir will hold 200 ml of reagent.  The VP 540PCB reservoir also is able to use the standard VP 540F baffles.  When the baffles are in place they dampen the wave action that occurs upon plate movement.  The baffles are constructed using the autoclaveable epoxy composite G10.

VP 542D

The VP 542D is constructed of autoclaveable polypropylene to fit into the SBS standard foot print with dimensions of 127 mm long, 85 mm wide and 15 mm tall with a cavity 12.5 mm deep.  The reservoir will hold 95 ml of reagent.  The VP 542D reservoir also has shorter (12 mm tall) G 10 baffles (VP 542F) strategically located to dampen wave action upon movement.  These baffles touch the bottom of the reservoir and have a half circle cut in them to allow fluids to drain from one section to another.
 

The VP 542D differs from the VP 542 in that it has 384 dimples in the bottom to help decrease the reagent dead volume.

VP 542M

The VP 542M is constructed of autoclaveable polypropylene to fit into the SBS standard foot print with dimensions of 127 mm long, 85 mm wide and 25 mm tall with a cavity 18 mm deep.  The reservoir will hold 95 ml of reagent.  The VP 542M reservoir also has 9.5 mm tall G 10 baffles (VP 542MF) strategically located to dampen wave action upon movement.  These baffles are recessed into the reservoir and do not touch the bottom of the reservoir.  This design allows pipets or pins to fit into the reservoir and still provide a high wall around the edge of the reservoir.  Also by placing the baffle above the bottom of the reservoir, eliminates the possibility of precious reagents being lost in puddles between the baffle and the reservoir bottom.  The VP 542M also has 384 dimples in the bottom to help decrease the reagent dead volume.

VP 542ML

VP 542ML black delrin lid with lip to cover VP 542M reservoir.  This lid is used to protect photosensitive reagents.  Overall dimensions are 132.8 mm by 90.5 mm by 5.6 mm thick at the edge.   The center portion of the lid is 2.9 mm thick with a 5.6 mm lip thickness, (2.7 mm lip overhang that captures the VP 542M reservoir).  This lid can be removed robotically and only weighs 45.5 grams.  

The photos to the right shows the VP 542ML used with VP 530-AL.

VP 541

The VP 541 is a dual chamber reservoir for 96 pipettors or 96 pin tools that is used to conserve deck space by placing 2 reservoirs in the same foot print.  For illustration purposes chamber 1 is filled with yellow dye and chamber 2 is filled with blue dye.  The dual chamber model is constructed of delrin and designed  to fit into the SBS standard foot print with dimensions of 127 mm long, 85 mm wide and 32 mm tall with two interdigitating chambers 25 mm deep.  Each chamber will hold 70 ml of reagent.  The interdigitation design (on 4.5 mm centers) of the dual chamber eliminates the need for wave dampening baffles.  This is important if the reagent reservoir is moved about the deck.   The reservoir is not autoclaveable. 

An outlet drain and fill version of the reservoir (VP 541T) is also available.  This facilitates filling and draining the dual reservoirs while on the work station between runs.

This dual reservoir design can also be used as a wash and blot reservoir in cleaning pin tools.

We have made many different custom reagent reservoirs.  The reservoir at the right was one we made  for a customer who wanted a compact reservoir with 11 rows and 10 columns, whose individual chambers would hold 1 ml of liquid, but had to be less than 10 mm in depth.  In order to accomplish this feat we created an interlocking design of 10 wells in the width of only 6 wells.  See the narrow part of the wells between the two arrows. 

If you have a similar challenging design or demanding requirements -  send them to us we enjoy solving these kind of problems.

We also have disposable polypropylene reagent trays for your convenience.  Some of our disposable reagent trays are taller and some are shorter than our reusable reservoirs.  In cases where clearance issues are important, one may have advantages over the other.
