The aspirator with trap flask FTA-1 with a 1L trap flask is designed for the aspiration or removal of any remaining alcohol or buffer from microtest tube walls during DNA / RNA purification and other macromolecule re-precipitation techniques. An ideal personal tool for independent operation away from an inline lab vacuum supply. The unit can also be used for routine operations of cells washing from culture medium and resuspension in a buffer. The operation principle is based on creating negative pressure in the trapping flask using an built-in micro-compressor. The collecting tip is connected with polyethylene tube to the trapping flask. Liquid is removed from the microtest tube when the collecting tip touches the solution surface.

A tube holder-organiser is conveniently located on the right hand side of the FTA-1. This can accommodate two tubes e.g. one for a hydrochloric acid solution and one for a distillate which is necessary for tip washing and storing, such that a tip can be reused. A suction microbiological filter eliminates risk of contamination from the trap flask with bacteria, viruses and infected particles. The suction microbiological filter is hydrophobic: with efficiency up to 99.9% it holds particles bigger than 0.027 micron, which are smaller than agents of Hepatitis A, B and C.

The use of an aspirator is preferential to using a generic laboratory vacuum line as it restricts the possibility of contamination and can be used exactly where the operator is located i.e. no need for a dedicated position in the laboratory to perform the aspirator.

• Compact, efficient, easy to use
• Flexible for the user by offering a choice of either a single tip operation or a multi-tip option with 8 tips for use on standard PCR type plates
• Integrated micro-biological filter is hydrophobic and designed to trap any bacteria, viruses or infected particles which may have been present in the aspirated solutions
• Can stand directly inside a workstation, supplied with a slim 12V power cord
