Dispensette S Organic Bottletop Dispenser Adjustable
Product Description
Description
The "floating piston" design of the Dispensette®S forms a zero-wear sealing system with outstanding sliding properties. Optimized flow channels make dispensing and priming even easier - particularly in instruments with large volumes.
Features:
- Simple to mount discharge tube available with or without integrated recirculation valve
- Designed without additional sealing rings for ease of cleaning and maintenance
- Replaceable discharge valve with the safety valve
- Olive-shaped filling valve for firmer attachment of filling tubes
- Improved flow technology results in faster priming
- Scalloped track for secure volume setting on analog dispensers
What is the difference between a Dispensette® S and a Dispensette® S Organic?
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. Because of the different construction and chemical compatibility, parts from a Dispensette®S should not be used with a Dispensette®S Organic, and vice versa.
