TQMTEC Quadra WashS

The Quadra Wash2 workstation is a small footprint - self contained,

automated microtiter plate washing station, ideal for both biochemical

assays such as ELISA and/or cell-based workflows. The unit supports

washing cycles with two different concentrations of buffered solutions,

such as Phosphate Buffered Saline (PBS) and/or water.

Dispense/aspirate volumes and rates are set with simple pressure/time

adjustments allowing the user to program repeatable fill/dispense

volumes at known rates with integrated volume check function, which

provides feed-back for quality control. Two separate inputs are provided

for buffered solution, used in the wash cycle. The solutions are

contained in a 10 Liter pressurized (2 - 5psi) PVC bottle. The effluent

from the wash cycle can be aspirated to, and retained in, an Autotrap™.

The Autotrap is equipped with a high level float that prevents overflows.

It can also be emptied to a waste disposal system at the flip of a switch,

by pressurizing the container from the Quadra Wash2 control panel.

The instrument is available with two separate heads for 96 or 384-well assays. Both heads are based on a unique

concentric wash/aspirate needle design which can be set up to a depth of 0.7 inches. The assay sits on a platform

that can be programmed to move in an x/y pattern during an aspirate/dispense cycle to maximize well-bottom wash

coverage. To ensure uninterrupted use, the modular design allows the user to detach and wash the

polypropylene/stainless steel head between runs.

The instrument is programmed via a simple

integrated user interface. The user can program

multiple "named" wash cycles of dispense, soak

and aspirate time-pressure intervals - no

external PC is needed. Each wash cycle can be

programmed, saved and recalled from memory

supporting walk-away automation.
