Prospenser Bottle-Top Dispenser

Overview

Bottle-Top Dispenser with Anti-drip valve

The easy-to-use Prospensers deliver trouble-free and reliable dispensing of liquids including strong acids, bases and solvents.

All models are fitted with an anti-drip safety valve, a feature which guards against drips when the Prospenser is not in use. A fine adjustment mechanism allows even greater reproducibility for repeat dispensing. The Prospenser features easy-to-adjust calibration mechanism.

Unlike other bottle-top dispensers, Prospenser’s glass barrel can be disassembled from the pedestal for thorough cleaning. This also ensures that in the unlikely event of damage the glass barrel can be replaced as a spare part.
