Washers designed for the automatic removal of dirt and/or stains (i.e., washing) from labware such as glass and plastic beakers, test tubes, and glass slides. These washers typically consist of a stainless steel washing compartment that is resistant to high water temperatures and corrosive chemicals, horizontal loading tracks or perforated shelves, and spindle headers, which are rows of hollow rods that allow water to penetrate difficult-to-reach vessel interiors. Labware is loaded into carrier baskets that slide onto the horizontal loading tracks or perforated shelves of the washer compartment. Labware/surgical instrument washers perform cycles of operations that typically include water prewash, enzyme treatment, detergent wash, heated rinse, and drying. The washers are available in freestanding, undercounter, recessed, or built-in (pass-through) configurations; they are used in clinical laboratories and in hospital central supply departments.
