Genevac's Mivac Speedtrap frost-free cold trap provides volatile solvent recovery and enables the freeze drying of up to 250ml of aqueous samples.
The Speedtrap is suitable for use with a wide range of solvents, from volatile organic solvents through to water and even higher boiling point solvents including 1,4-dioxane, tertiary butanol and cyclohexane.
While it is designed to complement the Mivac series of concentrators, it can also be used with other manufacturers' concentrators, provided that the solvents concentrated are compatible.
The Speedtrap can be used with a high vacuum pump as a standalone small-volume freeze dryer, or with a concentrator to become a combined concentration and freeze-drying system.
It is very small in size and requires little bench space, being only 212mm (8.3in) wide.
The Speedtrap operates with the cold condenser coils suspended directly in the vapour path, so that solvent vapours condense directly onto the coils and run off into the collection vessel below.
There are many benefits to this method: it is highly efficient, with more than twice the condensing power of similar cold trap systems; users can quickly see the solvents in the trap; and emptying the trap is easy, requiring no defrosting.
An automatic defrost mode ensures that the user does not need to spend time defrosting the system, even when using water.
The collection vessel is removed with a simple quarter turn, allowing the safe disposal of the solvents.
