Biosan FTA-1 and FTA-2i aspirator systems

Biosan’s self-contained aspiration systems, the FTA-1 and FTA-2i, are designed for the removal of supernatants from microtest tubes during DNA/RNA purification and other centrifugation steps, as well as for cell culture aspiration in biological safety cabinets.

The aspirator operation principle is based on creating negative pressure in the trap flask using a built-in, microcompressor-controlled diaphragm pump. No vacuum source is necessary.

The collecting tip is connected with a polyethylene tube to the trap flask. Liquid is removed from a tube when the collecting tip touches the solution surface. A tube holder-organiser is conveniently located at the right-hand side; it accommodates two tubes (eg, for washing solution and storage).

The FTA-1 is the more basic device, with a 1 L Schott bottle for waste collection and single-speed operation. A 200 µL yellow tip connects to the tubing. An 8-channel manifold is available for microplate aspiration.

The FTA-2i is the advanced option, with a 2 L waste collection bottle, liquid level detection, a variable speed control knob, multiple attachments for microplates (with disposable tips), a blue or yellow tip attachment, a hand controller for aspiration regulation and metal long tips for reaching into falcon tubes or dishes.
