Dispensette S Organic Bottletop Dispenser, Analog, Adjustable with Standard Valve, 0.5-5mL (BrandTech)

The Dispensette S Organic bottletop dispenser is supplied with: discharge tube, valve mounting / calibration tool, polypropylene adapters, telescoping filling tube, performance certificate, and operating manual.

The Dispensette S Organic has much in common with a Dispensette S, however there are two major differences. The Dispensette S Organic has a glass piston, rather than a PFA-coated piston. This optimizes it for use with concentrated acids and organic solvents that can interact with the PFA, but makes it less useful for bases. In addition, the valve spring in the Dispensette S Organic is tantalum (vs. platinum-iridium alloy) allowing it to be used with peroxides, again, at the expense of compatibility with bases.
