About the Dispensette S

Choose the Dispensette® S for the widest chemical comability of all Dispensette S. It can be used with most acids, bases, saline solutions, as well as many organic solvents. The Dispensette® S Organic has a glass piston that optimizes it for use with concentrated acids and combinatorial chemistry solvents, concentrated acids such as HCl and HNO3, trifluoroacetic acid (TFA), tetrahydrofuran (THF), and peroxides, but makes it less useful for specific bases. Use Dispensette S for dispensing of most acids, bases, saline solutions, and organic solvents. It has a PFA-coated piston that is highly compatible with bases, but which should not be used with concentrated acids or organic solvents that can interact with the PFA. The valve spring for the Dispensette S is made of a platinum-iridium alloy which supports the wide compatibility of the dispenser, especially with bases. Materials in the Bottletop Dispenser that will come into contact with the media being dispensed include Borosilicate glass, Al2O3-ceramic, platinum-iridium, ETFE, FEP, PFA, PTFE, and PP.
