We have assembled the largest collection
of magnetic bead separation blocks in the research market. We have
systems for a large variety of microplates found on this page and we
have a separate page for vials, tubes, bottles and larger containers. Our NdFeB separation magnets are also
the strongest available varying from 48 to 52 MGO. We also have
these in various sizes and shapes from cylinders, squares and
rectangles. If we don't have a separation block to fit your plate
we will custom build one for you. It's not special, it's what we
do. |

All of our magnetic
separation blocks are designed to fit into both the VP
771G-4R (on the left) and the VP 771G-4RM bases on
the right. The Bases have an SBS dimensioned
microplate base and support structures that hold both the
separation block and the microplate in perfect alignment.
The difference between the two bases is that the VP 771G-4R
is shorter with a shorter base and shorter support
structures. |
|
 |
|
| |
Because of the short base,
the VP 771G-4R is not compatible with our aspiration and
dispense manifolds. However it can be used with
robotic aspiration and dispense systems. We
built the VP 771G-4RM so it would be compatible with our
manual aspiration and dispensing systems by making the base
and the support structures taller. The VP 771G-4RM can
be used with both manual and robotic applications. We
recommend using this base in all applications except where
there is a "Z" limitation.

VP 771MM is a 7 NdFeB bar separation system that can
be used to separate magnetic beads in 6, 24, 48 and 96 microplates.
This system uses our VP 783NR-3-12-75 bar magnets that are 50 MGO. The system mates to and includes a VP 771G-4RM
which holds and registers the microplates to the VP 771MM.
The VP 771G-4RM is designed to fit onto
SBS plate holders and to hold SBS dimensioned microplates. |

The photo on the right illustrates how
the VP 771MM fits into a
VP 177AD-1 -PLUS
dispenser. The wells of a 96 well microplate line up perfectly
with the dispensing tubes of the VP 177AD-1_PLUS. The processing
of plates for magnetic bead assays using V&P's magnetic separation,
aspirating and dispensing systems is very easy. |

The VP 771E-2
Magnetic Separation Device is designed for high-throughput bio-separation
using paramagnetic particles in 96-well microplates with an open
architecture on the bottom so the magnetic posts can protrude between the
wells. Open architecture plates such
as the
Greiner 655101 Flat-Bottom
Well Polystyrene
Greiner 650101 U-Bottom Well Polystyrene
Corning 3956 Clear V-Bottom Deep Well 0.5mL Polypropylene
Corning 3958 Clear V-Bottom Deep Well 1.0mL Polypropylene
and most other microplates that
have spaces between the wells accessible from the bottom of
the plate.
Dimensions:
Width - 127.76mm
Length - 85.48mm
Height - 28.58mm
The photo to the right illustrates paramagnetic
bead in a microplate prior to being place on a VP 771E-2 |
|
 |
|
| |
By placing a powerful (48 MGO Neodynium
Boron) magnet between every 4 wells, the paramagnetic beads are pulled to the
side of the wells permitting the aspiration of the supernatant from the center
of the well or from a corner. See our slant angled manifold
VP 178D or the
VP 179A - VP 178BJ
aspiration manifold jig system for removing supernatants from 96 well
microplates.
We also offer several dispensing systems
for adding bead wash solutions to the 96 well microplates
while on the magnetic separation block (VP
177AD-PLUS,
VP
177AD-1-PLUS and
VP 179A jig
system with either the
VP
178JD-PLUS or
VP
178BJD-PLUS).

The tight pellets produced by the VP
771E-2 are illustrated in the photo to the right. |
|
 |
|
| |
The VP 771E-2 has an
SBS foot print that fits into the angled VP 381E. This holds the
plate at angle which in conjunction with the angled aspirating tubes
placed in the lowest corner of the wells facilitates the complete removal
of liquid from the wells while leaving the pellet held to the side of the
wells. |

pelleted beads. |

The VP 771H
Magnetic Separation Device is designed for high-throughput bio-separation
using paramagnetic particles in 96-well microplates with
either a flat solid bottom so there
are 9 magnetic posts surrounding
each well to attract the magnetic beads to the bottom of the
wells or it can also function with conical well (PCR) 96
well plates to attract the magnetic beads to 9 sides of each
well as the conical tips fit into holes between the magnets.

hole and magnet post post pattern of the VP 771H.

By placing 9 powerful (48 MGO Neodynium
Boron) magnets around every well, the paramagnetic beads are pulled to the
side of the wells permitting the aspiration of the supernatant from the center
of a flat bottom well or from
the bottom of a
conical well. See our
aspiration systems at
VP 177A-1,

The VP 771G-4
Magnetic Separation Device is designed for high-throughput bio-separation
using paramagnetic particles in 384-well microplates (flat bottom or
conical (PCR plates). By placing 4 powerful (48 MGO Neodynium
Boron) magnets around every well, paramagnetic beads are pulled to the
four corners permitting the aspiration of the supernatant from the center
of the well. The photo to the right illustrates
the 2 components of the VP 771G-4, the VP 771G-4S magnetic
separation plate and the VP 771G-4R registration system for
microplates. These two units working in tandem
can accommodate any style of 384 well microplate and any
microplate holder system.
See our VP 179A - VP 179BJ
aspiration manifold jig system for removing supernatants from 384 well
microplates. We also offer a dispensing system for
adding bead wash solutions to the 384 well microplates while
on the magnetic separation block, the
VP 179A -
VP 179BJD-PLUS. |
|
 |
|
| |
The VP 771G-4
conforms to the SBS footprint (127.7 mm x 85.48 mm) so that it can be
placed in any robotic deck station or other device with a SBS holding
profile. The VP 771G-4 is also designed as a low profile device with
only 7.5 mm Z height. Microplates can be placed on the VP 771G-4 and
will be registered by the trace around the edge of the device. This
feature of the VP 771-4 allows compatibility with any plate processing
laboratory robot with a plate gripper.

Griener polypropylene 384 microplate with Promega super-paramagnetic beads

The V&P 48 Mega
Gauss Orestad magnets High-energy neodymium iron boron
magnets placed in 4 corners around every well is able to produce 4 very
tight pellets in the corners of very well leaving the center of each well
available for aspiration. The strength of our high energy magnets
leads to rapid separation of paramagnetic beads and holds the beads
tightly to the bottom of the wells.
|
|
 |
|
| |
The VP 771G-4 is
compatible with most 384 well microplates as well as conical well PCR
microplate as illustrated on the right. In order to accommodate the
conical well PCR the VP 771G-4 has 384 holes between the magnets as
illustrated in the photo below and to the right.

The aluminum registration base (VP
771G-4R) is attached to the separation block VP 771G-4S via
4 allen screws in the locating fingers. This unique
ability to use as a low profile separation block or in a
raised position allows it to be used in all microplate
holding systems. Also the locating fingers allow the
separation units to be stacked on top of each other without
being stuck together. |
