Microlit Bottle Top Dispenser (1-10ml) - Chemical Compatible Bottle Dispenser

  • SAFE, PRECISE, ACCURATE – Our bottle top dispensers can be used to dispense precise amounts of chemicals, reagents, organic and inorganic solvents, oils and more from bottles or other containers. Bottletop dispensers allow you to safely dispense a fixed amount of liquid directly from a bottle to a receiving container. Bottle top dispensers help reduce the loss of reagents, save time, and reduce risk..
  • JAM FREE TECHNOLOGY – The ETP O-Ring ensures proper lubrication for the PTFE piston against the glass barrel to ensure a smooth and jam-free dispensing experience..
  • CHEMICAL COMPATIBILITY – Microlit dispensers utilize SpringlessValve technology and a PTFE piston. The absence of spring in the valve and the use of inert materials ensures high chemical compatibility with a wide range of acids, bases, solvents, organics, and inorganics (complete compatibility chart provided)..
  • USE WITH CONFIDENCE – Microlit bottletop dispensers are ISO 9001, ISO 13485, ISO 17025, and CE certified. Outperforms ISO 8655 standards (0.5% accuracy) in practical lab environments. A calibration certificate guaranteeing ISO level accuracy and precision is provided and is valid for one year. Our dispensers are fully autoclavable at 121° C and 15 PSI for 10-15 mins..
