The Bio-Tek ELX405 UD/DW Microplate Washer is designed specifically to rapidly wash 96 or 384-well microplates and includes Bio-Tek patented Dual-Action manifold to ensure optimal performance and easy maintenance. The ELX405 UD/DW microplate washer comes standard with Bio-Tek unique AutoPrime and AutoRinse functions for reliable performance. Programming is made easy through simple keypad interface with independent control of plate position during dispense and aspiration cycles, as well as fully programmable fluid volumes and flow rates, shaking, and soaking. Easy maintenance with a selection of pre-programmed routines for problem-free operation and run protection via fluid detection, fluid flow, and vacuum sensors. ELx405 UD/DW Microplate washer Manifold Description: Single manifold with 96 sets of aspirates and dispense tubes arranged in an 8x12 array to process 96-well microplates. Average residual volume in the microwells is ≤ 2 µL per well (or < 5 µL for washer, after a 3-cycle wash, when 300 µL of deionized water with 0.1% Tween 20, or buffer equivalent, is dispensed per well into a Costar 96-well flat-bottomed plate. The aspirate height adjustment is optimized for the plate prior to testing. Vacuum Filtration; 96-Well Filter; Average increased weight of the plate is ≤ 1.2 grams after dispensing 300 µL of deionized water per well into a Millipore MSHVN4450 96-well 0.45µm plates and vacuum aspirated for 30 seconds at vent diameter 0.047” (no plug) and blotted. Dispense Precision; ELx405 Select with Single/Dual 96-Tube: ≤ 3.0% CV (or < 4.0%CV for washer serial numbers < 204272), when dispensing 300 µL per well of deionized water with 0.1% Tween 20, with FD&C 1 blue dye at a rate of 300 µL per well, per second into a Costar 96-well flat-bottomed plate. The absorbance of the solution is read at 630 nm and 450 nm reference.
