The new Dispensette® S Trace Analysis features many of the same safety and convenience features of the Dispensette® S, but is optimized for the needs of dispensing high purity reagents.
Designed to attach directly to your reagent bottle eliminating poured transfer, the Dispensette® S Trace Analysis features a wiping seal piston to minimize reagent exposure. Only the high purity materials are in the flowpath — PTFE, ETFE, PCTFE, FEP and PFA and sapphire for ball valves. Two models are available – one with platinum-iridium valve springs, and one with tantalum valve springs for different chemical compatibility and for different metal ion analysis. After following a field-tested cleaning procedure, metal ions are typically in the low PPB or even PPT range. The platinum-iridium model is also suitable for the dispensing of hydrofluoric acid. The dispensing cartridge is replaceable Instruments feature a sliding pointer, well suited for rapid volume changes from one end of the range to the other. A scalloped inner track allows for easily reproducible settings.
The Dispensette® S Trace Analysis is available with or without a recirculation valve that allows easy priming without ‘spitting’ or wasting of reagent Dispensette® S Trace Analysis bottletop dispenser with 45mm thread is supplied with performance certificate, telescoping filling tube, recirculation valve and recirculation tube (if specified), valve mounting tool and three fluoropolymer adapters to fit 28mm, 33mm and S40mm bottles.
