This bottle top dispenser has a sophisticated yet simple design to ensure ease of operation, superior safety, and low maintenance. They offer superior performance stability with Solid Calibration®, allowing for simple in-lab calibration, delivering accuracy and long-term reproducibility. A series of calibrated, permanently fixed stops make volume selection quick and repeatable. The wetted components are chemically inert. Made from borosilicate glass, PTFE, ETFE, PFA, ceramic and platinum-iridium, these bottle-top dispensers have a 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; and can be disassembled in seconds for cleaning or 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 33 mm screw-neck finish and are supplied with adapters to fit 28, 38 and 45 mm finishes.
