8-Channel Microplate Washer BioTek 50TS8
PART NO. 4AJ-6287399

Microplate washer 50TS8 w. 8-channel wash comb, for 96 well plates and 8er strips

Microplate Washer 50 TS8


The 50 TS automates the aspirate, dispense shake and soak steps required for many assays including cell-based assays, biomagnetic and polystyrene bead-based assays.

A few examples of the many important applications for 50 TS are:

  • ELISA assays
  • Cell-based assays
  • Biomagnetic separation
  • Vacuum filtration
  • Luminex® xMap® assays
  • Multiplex assays


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.

Application versatility: ELISA to cell-based assays 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.

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

Pre-defined, automated maintenance routines, including daily and overnight protocols keep the fluid path clean and prevent buildup of salt, protein or other material that can block manifold tubes, causing inadequate washing.

Automated switching of up to 3 buffers

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

The 50 TS offers convenient, powerful onboard software for easy programming and operation. To extend programming capabilities, LHC Software is available for computer control.

LHC Software allows computer-based programming of multi-step processes and it is used for integrating BioTek’s multi-mode washer dispensers, washers and dispensers into robotic systems. You can operate the system under computer control via LHC, or create protocols in LHC and download to the instrument for recall and execution.

LHC Secure software offers features to facilitate compliance to FDA directive 21 CFR Part 11 with computer control of BioTek’s Multi-Mode Washer Dispensers, Washers and Dispensers.
