PW-812 Microplate Washer

Microcomputer control, automatically completes the cleaning of 48-well and 96-well microplates in various enzyme-immunoassay, time-resolved and chemiluminescence experiments.

· The menu allows automatic plate washing, rinsing, maintenance, and shutdown with a single function key press.
· A 3.5-inch LCD screen displays all plate washing parameters simultaneously, with customizable program settings.
· Supports up to 100 washing programs, each storing a unique experiment name and microplate configuration.
· The maintenance program enables hardware diagnostics and batch storage of washing programs, with user-defined limits.
· Pause and stop functions allow operation interruption via the pause or back button.
· Digitally displayed microplate position parameters, accurate to 0.1mm, compatible with various domestic and international microplate standards.
· Two-point positioning aspiration ensures an average residual washing liquid per well of <0.7μl.
· Precision wash head design maintains a liquid dispensing accuracy CV of <1.5% across 96 wells.
· Specimens can be placed freely for cross-row washing, with patented technology allowing incomplete row washing without refilling.
· Quick selection of washing strips using corresponding strip keys enhances convenience.
· Microplate soaking, shaking, and bubble-removal functions minimize interference adsorption during reactions.
· Multiple washing solution channels are available, selectable via program defaults or manual switching.
· Proprietary high-efficiency filters in each wash solution bottle prevent clogging and reduce the occurrence of blocked wells.
· Automatic distilled water rinsing during startup, shutdown, and between washes minimizes cross-contamination.
· The wash solution pipeline rinsing function, with adjustable timing, effectively prevents crystallization.
· A pressure regulation valve allows adjustable liquid dispensing time and pressure, preventing excessive pressure damage.
· Detachable microplate tray with sloped bottom design and suspended storage position ensures automatic liquid drainage, preventing contamination and facilitating maintenance.
· A patented wash head bracket design prevents misalignment or detachment during washing.
· Wash solution bottles feature uniform volume scale lines for easy reagent preparation, with an automatic waste liquid full alarm.
· A transparent biosafety cover enables easy observation of the washing process while isolating the laboratory environment.

The PW-812Plus features an automatic waste liquid drainage function.
