VWR變速化學試劑泵是為液體傳遞而設計的，流速可根據用戶要求調節，泵的電動驅動部件，對不同粘度的液體都適用。試劑泵配有化學防腐蝕的部件，304號不銹綱部件和“杜邦”生產的聚酯材料。

Designed for pulseless fluid transfer at variable flow rates. Direct-drive engineering provides maximum motor power to the pump. Step-less “continuous sweep” variable control provides precise seamless speed control. Pumps fluids with a viscosity of up to 200 centipoise. Pump features a suction lift of 3m (9''10") wet, 18cm (4") dry. The chemical-resistant wetted parts are DuPont Delrin*, 304 stainless steel, Buna N, and DuPont Teflon* resin. Flow is easily reversible for draining tubing.

UL listed and CSA approved.
