BRAND Bottle-top Dispenser
At BRAND you will find dispensers for dosing liquids in the laboratory. Discover our Dispensette® S and seripettor® bottle-top dispensers here.
The Dispensette® S is your number 1 solution for direct bottle-top dispensing. It makes dispensing liquids safer and easier. Thanks to the special functional design of the piston, the Dispensette® S operates smoothly, requiring minimum effort when filling and dispensing. The volume is adjusted quickly and set reliably. The Dispensette® S bottle-top dispenser has a proven track record in demanding continuous-use applications and when used with aggressive substances.
Dispensette® S (red color-code): Ideal for dispensing aggressive reagents, including concentrated bases and acids such as H3PO4, H2SO4 (except e.g., HCl, HNO3 und HF), saline solutions, as well as many organic solvents.
Dispensette® S Organic (yellow color-code): Ideal for dispensing organic solvents, including chlorinated and fluorinated hydrocarbons (e.g., trichlorofluoroethane and dichlormethane), acids like concentrated HCl and HNO3 (except HF), trifluoroacetic acid (TFA), tetrahydrofuran (THF) and peroxides.
The Dispensette® S Trace Analysis provides outstanding performance for precise volume dispensing of high-purity media for trace analysis. Also suitable for HF with platinum-iridium valve spring.
Plastics in contact with media consist of high-purity materials such as PTFE, ETFE, FEP, and PFA. The purest sapphire is used for replaceable valves. Depending on the application, platinum-iridium or tantalum are available as spring materials.
A field-tested cleaning process before use in trace analysis is described in the operating manual.
If contamination of the bottle contents must be avoided, we recommend using the device without the recirculation valve.
The 45 mm standard thread plus the included adapters fit most common lab bottles.
The valve block can be rotated 360° so that the bottle label always faces the user for safety.Telescoping filling tube adjusts to different bottle sizes.
Easy disassembly for replacement of the dispensing cartridge
