Aspirator with trap flask FTA-2i is designed for aspiration or removal of alcohol, buffer and liquid from reaction vessels (e. g. during DNA / RNA purification or other macromolecule reprecipitation techniques).
The operation principle of the aspirator is based on creating negative pressure in trapping flask using built-in microcompressor. The collecting tip is connected with PE tube to the trapping flask. Liquid is removed from the reaction vessel when the collecting tip is in contact with the solution. A tube holder-organiser is conveniently located at FTA-2i right hand side; it accommodates two 1.5 / 2 ml tube slots necessary for collecting tip washing and storing, so that a tip can be re-used. The FTA-2i is equipped with a level sensor that detects excess liquid with consequential prevention of the overflow by automatically switching off the pump with a sounding alarm indication. The device is supplied, as standard, with vacuum regulation control knob that allows to smoothly select a preferable aspiration speed.
