An ELISA Reader & Washer – A Beginners Guide to Buying

The ELISA Reader is an integral part of most mid-size laboratory systems today. ELISA tests cover a broad spectrum of tests from Infectious to Vector-Borne to Wellness related diseases. This instrument is a microprocessor-controlled, general purpose photometer system designed to read and calculate the result of assays, which are read in a microtiter plate. Hence the alternate name Microplate Reader. The ELISA Washer or Microplate washer is designed to wash the microwells as a part of the ELISA testing process. The performance of the ELISA test kits and reliability in their test results depend heavily on a good quality ELISA Reader and washer being used for performing the ELISA tests.
