Calibrex® digital 520 Bottle Top Dispensers
By DWK - Wheaton Science Products
Calibrex® bottle top dispensers have a sophisticated yet simple design to ensure ease of operation, superior safety, and low maintenance. Solid Calibration® offers superior performance stability, and calibration in-lab is easy.
A series of calibrated, permanently fixed stops make volume selection quick and repeatable, not dependent on operator skill. The wetted components are chemically inert; they are made from borosilicate glass, PTFE, ETFE, PFA, ceramic and platinum-iridium, providing high chemical resistance. Rotating the selector ring while viewing the settings in the fixed window makes volume selection fast, easy and accurate. The selection window can be adjusted to one of four positions in relationship to the delivery nozzle so the dispense volume can be conveniently seen, no matter how the work area is arranged. The dispenser also rotates 360° on the bottle.
Dispenser can be disassembled in seconds for cleaning, and can be autoclaved fully assembled. The syringe barrel is encased in a protective sleeve to prevent breakage and to eliminate the risk of spilling. The dispensers fit bottles with a 33mm screw-neck finish and are supplied with adapters to fit 28, 38 and 45mm finishes.
