The 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. 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.
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
The Dispensette®S Trace Analysis bottletop dispenser is supplied with: discharge tube, valve mounting/calibration tool, ETFE and PTFE adapters (GL28, GL32, GL38, S40), telescoping filling tube, recirculation tube (optional), performance certificate, operating manual, and one year warranty.
