  • Page 8: Chapter 1: Introduction To The Wellwash Microplate Washer

    Chapter 1: Introduction to the Wellwash Microplate Washer The Wellwash (Figure 1) is a microplate washer. It is designed to use a 96-well plate format in both landscape and portrait orientation. The 96-well plates and strips are designed to be washed in 1x8 or 1x12 format.

  • Page 9: Principle Of Operation

    Principle of operation The Wellwash can be used to wash and prepare plates for a variety of test routines, mainly in ELISA applications. The Wellwash (Figure 1) is a microplate strip washer for automated washing, aspiration, dispensing and shaking of 96-well plates and strips in landscape or portrait plate orientation. The instrument is equipped with one wash and one waste liquid bottle each with a cap, tubing and a liquid level sensor.

  • Page 10: Chapter 2: Installation

    Chapter 2: Installation Warning! The Wellwash weighs 8 kg [17.6 lbs.] and care must be taken when lifting it. For more information on main parts of the instrument, refer to Chapter 3: “Wellwash Main Parts”. Unpacking How to unpack Move the packed instrument to its site of operation. To prevent condensation, the instrument should be left in its protective plastic wrapping until the ambient temperature has been reached.

  • Page 11: Setups

    Setups Warning! All parts of the instrument that come into contact with potentially infectious materials must be treated as potentially infectious areas. It is advisable to adhere to applicable safety precautions, such as the wearing of disposable powder-free gloves, safety glasses, and protective clothing, to avoid potential infectious disease contamination when performing cleaning procedures and also when making adjustments to the instrument.
