New Dispensette S Bottletop Dispensers

Ideal for HPLC and combinatorial chemistry labs, the Dispensette® S Organic Bottletop Dispensers from BrandTech Scientific build on fifty years of leadership in dispensing technology. The newly designed instruments have such advanced features as improved safety valves, faster priming, easier volume selection, and even lower operation forces. All seals have been eliminated to have even less wearing parts to replace over time. The Dispensette S Organic features a special version of BRAND's proven "floating" piston system specially suited for organic solvents, concentrated acids and peroxides. Features: Handles critical solvents: The Dispensette S Organic handles your critical solvents: THF, TFA, methanol, acetonitrile, methylene chloride, DMF and DMSO. The instrument is also the right choice for HNO3 and HCl, and peroxides, but is not suited for alkaline solutions or hydrochloride salts. Enhanced safety features: The Dispensette S Organic adds this specialized chemical compatibility to the familiar safety and convenience features of the popular Dispensette S, including reinforced discharge tube with threaded safety cap, recirculation valve to conserve solvents and reduce "spurting" while priming, safety discharge system to reduce the chance of inadvertent dispensing, and telescoping filling tube and thread adapters to fit to most lab bottles. Available in digital and analog models: The Dispensette S Organic comes in analog and digital models with bright yellow trim for easy identification. Accessories are available for serial and drum dispensing. Limitations of use: The parts of the Dispensette S Organic which come into contact with the liquid are made of high-grade materials such as ETFE, PTFE, PFA, borosilicate glass, FEP and tantalum. The Dispensette S Organic should not be used with any liquids that attack these materials.

The BRAND® Dispensette® S Trace Analysis bottletop dispenser is designed for dispensing high-purity chemicals for trace analysis. With a fluid path composed of materials such as PFA, PTFE and sapphire, the Dispensette S Trace Analysis can be used for analysis in the PPB and PPT range. With a volume range of 1-10mL the Dispensette S Trace Analysis is available in two different models, depending on the reagents and testing performed; one with valve springs constructed of platinum-iridium, and one with tantalum springs. The platinum-iridium version is also suitable for dispensing of hydrofluoric acid. The instrument features many of the safety and convenience features of other Dispensette S models such as a removable recirculation valve. The wiping seal dispensing cartridge helps maintain reagent integrity, and can be easily replaced by the user. Replacements are supplied with quality certificate. An optional flexible discharge tube (not for HF) facilitates serial dispensing.
