50 TS Washer


The BioTek 50 TS washer offers excellent microplate washing performance. Ideal for use as an ELISA washer, the system is also well suited for cell-based assay washing. The 50 TS can process biomagnetic or polystyrene bead and vacuum filtration protocols as well. The color touch screen provides a visual interface that makes creating protocols fast and intuitive. When used with the 800 TS absorbance reader or other detection system, the 50 TS delivers convenience and high-quality results to your laboratory plate washing workflows.



   High quality & performance, affordable price

 High quality, high performance automated microplate washing at an affordable price

These qualities make BioTek the #1 plate washer brand in the world. As an ISO certified and FDA registered Medical Device manufacturer, BioTek understands the importance of accurate, repeatable results, low maintenance, and reliability in the clinical and research laboratory.


  ELISA to cell- and bead-based assays


Applications for the 50 TS extend far beyond simple dispense and aspirate routines typical of many ELISA processes. Optimize fluid delivery for gentle cell-based assay washing, or run bead-based processes with the available biomagnetic and vacuum filtration modules.

96 ring magnets

   Quick, easy programming and operation

 Color touchscreen for quick, easy programming and operation

The 50 TS software includes pre-defined protocols with commonly used wash parameters for quick selection. Creating custom protocols onboard the 50 TS is easy – the touchscreen and menu-driven software make multi-step program creation intuitive and simple!


   Automated maintenance routines for continued reliable operation


Routine maintenance ensures continued reliable washing and excellent assay performance. The 50 TS offers pre-defined, automated maintenance routines including daily and overnight protocols. These keep the fluid path clean and prevent buildup of salt, protein or other material that can block manifold tubes and cause inadequate washing.

Automated digital microscopy to 100x

   Automated switching of up to 3 buffers

Four imaging modes, multiple imaging processes

To facilitate complex wash protocols or automated maintenance routines, the automated buffer switching capability adds even greater automation to the system.
