BRAND® Dispensette® S Bottletop Dispenser

The new bottle-top dispenser Dispensette® S:

  • New discharge tube with or without recirculation valve
  • New valve system, no sealing rings necessary
  • Faster priming due to improved flow technology
  • Less force needed during dispensing especially for instruments with large volumes
  • Volume selection with interior scalloped track for analog devices, enhances setting reproducibility
  • New 1 ml size digital and analog

Dispensette® S
Dispensette® S supports a very wide range of applications for the dispensing of aggressive reagents – directly from the supply bottle: such as concentrated bases and acids like H3PO4, H2SO4 (with certain exceptions such as HCl, HNO3, HF, etc.), saline solutions, and a variety of organic solvents.

Dispensette® S Organic
Dispensette® S Organic is ideal for dispensing organic solvents: such as chlorinated and fluorinated hydrocarbons like trichlorotrifluoroethane and dichloromethane, or acids like concentrated HCl and HNO3 (except for HF), as well as for trifluoroacetic acid (TFA), tetrahydrofurane (THF), and peroxides.

For dispensing hydrofluoric acid (HF), we recommend the use of the* Dispensette® S Trace Analysis* bottle-top dispenser with platinum-iridium valve spring!

Easier dispensing and faster priming
In the "floating piston" design, the pistons and cylinders are fitted individually in such a way that the gap between them is just a few micrometers wide. This gap is filled by the fluid being dispensed, forming a zero-wear sealing system with outstanding sliding properties. Optimized flow channels make dispensing and priming even easier – especially in instruments with large volumes.

Simple to mount
The new discharge tube is easy to fasten and is available with or without a recirculation valve.

Fast calibration
With Easy Calibration technique, you can calibrate quickly and easily in the laboratory in just a few steps. BRAND also offers a factory calibration service.

Positive volume setting
In analog dispensers, volume setting is quick, secure and repeatable due to the interior scalloped track.

Designed without seals
All valves work without any additional sealing rings. That makes cleaning and preparation for autoclaving easier.
