VWR TOP DISPENSER HF BOTTLE 1-10ML

Details

Here is the corrected text: The VWR HF bottle top dispenser is designed with ergonomics and intuitive handling in mind, helping to dispense Hydrofluoric Acid with safety and precision. The dispenser is made with selected materials for the barrel and valve assembly, enabling it to be used with Hydrofluoric Acid (HF) as well as solvents and other reagents. The HF bottle top dispenser exhibits excellent chemical compatibility and helps achieve precision with reliability in practical laboratory environments. It features a re-circulation valve that prevents the loss of reagents during purging by redirecting them into the mounted bottle, facilitating bubble-free dispensing. A specially designed volume adjustment knob allows 180° rotation for easy and effortless volume setting. The dispenser also features a Springless Valve for smooth and jam-free functioning, a PTFE piston with ETP O-Ring for effortless piston movement and high chemical compatibility, easy and effortless volume setting, and a flexible delivery nozzle to change the angle of dispensing. The dispenser is fully autoclavable at 121 °C and 15 psi for 10 to 15 minutes, with reproducibility of 0.2%. Caution: Maintain instrument and reagent temperature between 10 to 40 °C (50 to 104 °F). Maintain reagent vapor pressure up to 600 mbar (maximum). Aspirate slowly above 300 mbar pressure to prevent the liquid from boiling. Kinematic viscosity should be up to 500 mm²/s, with relative air humidity between 20% and 90%. Use fluids with density up to 2.2 g/cm³. The dispenser meets ISO 8655 standards for accuracy and precision, and adheres to manufacturing standards ISO 9001, ISO 13485, and ISO 17025, with product certification CE. Each unit includes a telescoping suction tube, recirculation tube, five thread adapters (28, 32, 38, 40, and 45 mm), and an individual quality control certificate that documents the serial number and test values, confirming conformity according to weights and measures regulations as per ISO 8655.
