The new Dispensette® S builds on a half century of BRAND® bottletop dispenser experience. It features a floating piston design with even lower operating forces, a new safety discharge system, and an improved sealing system, eliminating sealing washers for even better reliability. Designed to attach directly to a reagent bottle, eliminating poured transfer. In addition to the product improvements, a new 0.1–1mL size is available.
- Floating piston eliminates seal wear
- Safety discharge system
- Better reliability
- Fits most reagent bottles directly
Choose the Dispensette® S for general-purpose dispensing of acids, bases, buffers, and many common solvents (NOT suitable for HF)
Choose from two different volume adjust mechanisms or fixed volume models. Analog adjustable models feature a sliding pointer with scalloped inner track, well suited for rapid volume changes from one end of the range to the other. Digital adjustable models are excellent for highly reproducible volume settings. All are available with or without a recirculation valve that allows easy priming without ‘spitting’ or reagent wasting. Many accessories, including adapters for nearly any unpressurized container, are available.
For hydrofluoric acid, choose the Dispensette® S Trace Analysis platinum-iridium. For concentrated acids, TFA, peroxides, THF, and other difficult solvents, choose the Dispensette® S Organic. A selection chart is available.
