Dispensette S Trace Analysis Bottletop Dispenser
Product Description
The Dispensette® S Trace Analysis 1-10mL 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. The 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.
New 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 can I dispense with the Dispensette® S Trace Analysis?
The Dispensette® S Trace Analysis is specially designed to dispense high-purity chemicals, with trace metal content of dispensed liquid generally in the low ppb range, or, depending on the application, even in the low ppt range. The platinum-iridium model is suitable for dispensing Hydrofluoric acid (HF), while the tantalum model is suitable for dispensing Hydrogen peroxide (H2O2). Additionally, the Dispensette® S Trace Analysis can be used to dispense Bromine since the ball valve, composed of Al2O3 sapphire, is denser than the ball valves in the Dispensette® S or Dispensette® S Organic.

* Hydrofluoric acid reacts slightly with sapphire resulting in mildly elevated aluminum values. To reduce these values we recommend discarding 3-5 dispensing of 2 ml each before performing the analysis.
