Description:

VWR® Bottle Top Dispensers provide laboratories with a highly precise and reliable liquid handling solution. The ergonomically designed dispenser is equipped with a PTFE piston and ETP O-Ring, offering excellent chemical compatibility, even with solvents. The re-circulation valve prevents reagent loss by redirecting unused liquid back into the bottle, allowing for bubble-free dispensing. The innovative Springless Valve™ ensures smooth and jam-free operation, while the volume adjustment knob allows for effortless 180° rotation for precise volume settings. The flexible delivery nozzle enhances usability by allowing users to adjust the dispensing angle according to their needs.

These dispensers are fully autoclavable at 121°C and 15 psi, making them ideal for sterile environments. They meet ISO 8655 standards for accuracy and precision and are manufactured according to ISO 9001, ISO 13485, and ISO 17025 standards. Each dispenser comes with a telescoping suction tube, recirculation tube, multiple thread adapters, and a quality control certificate for guaranteed performance.
