    I'm interested in purchasing this product to pump vegetable glycerin. Can this pump handle higher viscosity liquids?

      A:

      Bottletop dispensers are not designed for high viscosity fluids, unfortunately. You could use serological pipettes or a peristaltic pump instead.

  • Q:

    We use this bottletop dispenser with reagents to do a low-level lab silica test. A concern recently came up that the glass bottles that are recommended for use with these dispensers may be contributing silica to the reagent and resulting in poor test results. Is this a possibility and are there plastic bottles that would work with this dispenser?

      The 25208-04 features a built-in 30-mm threaded screw top and include adapters for 28-, 32-, 36-, 40- and 45-mm bottles. Therefore any bottle option with these cap sizes will work for you. I will email you some options to look over.
