Cleaning Pins On Robot Mounted Pin Tools


The most important aspect of using pin tools is to start with clean pins and then keep them clean so they will consistently deliver the same volume.  We recommend our Pin Cleaning Solution (VP 110) to clean the pin of protein and other residue buildup before you start an assay.  To quickly and efficiently remove the previous transfer from the pin we have several different wash reservoirs, flowing reservoirs and fountains to clean  96, 384 and 1536 floating pin tools.  These wash stations also are adapted so the blotting station is part of the washing station thus reducing the cleaning cycle time and the number of robot stations required for the cleaning process.  We also have other independent blotting stations (VP 540D)

Integral to the cleaning process of all pins is the blotting step between baths.  Lint particles in the slots or on pin tips, from standard paper towels, will interfere with the loading and unloading of liquid.  We have solved this problem.  The VP 540DB blotting system is a tray with the standard microplate foot print that contains a super absorbent polypropylene pad covered by a Lint Free Blotting Paper.  We strongly recommend that you use this or our other lint free blotting systems.

We have developed detailed procedures for cleaning pin tools on robot systems.
