Bottletop dispensers
You can easily and conveniently order bottle top dispensers from LABSOLUTE®, Brand, Hirschmann, Poulten & Graf, Socorex, Vitlab or other brands in the Th. Geyer online shop. The bottle-top dispensers with and without back-dispensing valve are a cost-effective way to measure liquids exactly and repeatedly. The dispensers have a choice of digital or analogue display and are supplied with adapters for all common bottle threads. The wetted components of the attachment burettes are made of inert materials, so that the dispenser can be filled and used with almost any chemical. In addition, there are particularly robust models for difficult applications such as hydrofluoric acid.
