These bottle-top dispensers are safe, reliable, and easy to use. Ideal for dispensing most acids, bases, saline solutions, and many solvents. The floating piston design provides smooth, one-handed operation, and eliminates polymer seal wear, for minimal service downtime. Dispensers can be directly fitted to standard GL45 bottles, or can be fitted to most common reagent bottles using the supplied adapters and telescoping filling tube, which eliminates poured transfer. The threaded safety cap removes easily, with or without gloves.
Choose from adjustable digital or analog models, in addition to fixed volume models. Easy Calibration™ digital models allow calibration adjustments in seconds without tools. SafetyPrime™ recirculation valve models reduce spurting during priming, help protect against inadvertent dispensing, and conserve valuable solvents. Valve block rotates 360°, allowing bottle label to always face the user.
Optional, flexible discharge tube can be moved easily over a series of vessels, simplifying serial dispensing of scintillation fluid and other liquids. The discharge tube has a safety handle that reduces the risk of chemical splash from tube recoil.
Optional remote dispensing system allows accurate dispensing from unpressurized drums and bulk refills. The dispenser may then be mounted as far as 10m (30') away from the container. Features a quick-release connector and an integral filter. NOWPak® adapter allows the use of economical and ecological NOWPak® bulk containers.
Caution: This dispenser should never be used with hydrofluoric (HF) acid, sodium azide, or chemicals incompatible with any of the materials of the flowpath (borosilicate glass, PFA, FEP, ETFE, PTFE, alumina ceramic, and platinum-iridium alloy). To dispense concentrated acids, fuming acids, tetrahydrofuran (THF), peroxides, or chlorinated and fluorinated solvents, use the Dispensette organic dispenser (see 72888-010 series). To dispense hydrofluoric acid, use the Dispensette HF dispenser (see 47746-470 series).
