The aspirators with trap flasks FTA-1 and FTA-2i are designed for routine aspiration of the supernatant alcohol/buffer from the walls of microtubes during DNA/RNA purification and other macromolecule reprecipitation techniques. Small, compact and easy to use. All in one system with integrated pump. Perfect for small volume aspiration. Fitted with hydrophobic microbiological filter that eliminates risk of contamination from the trap flask (efficiency up to 99.9%, holds particles bigger than 0.0027 micron). Built in micro-compressor creates negative pressure in the trap flask for removal of liquid from microtubes. Polyethylene tube connects the collecting tip to the trap flask.rrFTA-1 specifications:r- 1L trap flask for collection of aspirate from microtubes or microplatesr- Tube holder accommodates two tubes to store tip or optional 8 channel adaptorr- Dim.
