The Stat Wash™ is designed to wash immunoassays with professional precision, incorporating a high quality pump for push-button controlled dispensing and aspiration to reduce the risk of exposure to splashing biohazards. By eliminating the use of squirt-bottle washing, it provides clean, fast, and precise results without using expensive automated washers. It is compact and hand-held, easy to use and maintain, and is supplied with an 8-probe manifold, a 1L plastic wash bottle, and a 1L plastic waste bottle with a full sensor.
