For safe vacuum extraction of liquid residues. Basic equipment: Vacuum pump Collecting bottle made of PP, vacuum-resistant, autoclavable Screw cap with two quick-release couplings for tight sealing of the collecting bottle after the hoses are disconnected Ventilation insert for pressure compensation during autoclaving of collecting bottle Safety filter to protect the vacuum pump and surrounding area Silicone hose (3 m) for placing the extraction system away from the workbench Note: when the quick couplings are fitted, unscrew the cap before autoclaving and place it on the bottle. Extraction system AA model Lacquered aluminium housing Compact design, safety bottle holder mounted on high-performance vacuum pump Suitable for up to four sampling points (optional) Handle with AH 01 trumpet valve for attaching various suction instruments and a mechanical flow rate control system; incl. adapter for Pasteur pipettes, adapter for 1 ml pipette tips and angle adapter Vacuum pump with automatic cut-out. The pump cuts out automatically when extraction is completed using the handle and the final vacuum is reached
