Dispensette® S Trace Analysis Bottletop Dispenser
Dispensette® S Trace Analysis is the next generation bottletop dispenser for precise volume dispensing of high-purity media for trace analysis. It is especially suited for dispensing acids, bases and hydrogen peroxide in the volume range from 1 to 10 mL.
Components of the fluid path have been selected to only contain the highest purity materials, such as fluoroplastics and sapphire. The result is a trace metal content of dispensed liquid generally in the low ppb range, or even in the low ppt range, depending on the application. Both platinum-iridium and tantalum valve springs are available for application compatibility.
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 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
Specifications:
*Both platinum-iridium and tantalum valve springs are available for application compatibility.*
