The waste liquid suction device is mainly used for extracting culture medium supernatant or waste liquid in cell culture experiments, reducing the frequency of manual operation by experimental personnel, lowering the risk of pollution, and improving work efficiency. When used in a biosafety cabinet or ultra clean workbench, the culture medium supernatant or experimental waste liquid is sucked into the waste liquid bottle through a vacuum pump to avoid frequent manual pouring or the use of disposable straws by experimenters and reduce exposure risks.
It mainly consists of a vacuum pump, waste liquid bottle, suction head, suction tube, and control device. The vacuum pump is the core component that provides suction power; Waste liquid bottles are used to store waste liquid and are available in different materials and capacities; Suction heads and straws are used to suck up waste liquids. Suction heads come in various types such as single claw and eight claw to meet different suction needs; The control device is used to adjust parameters such as vacuum degree and flow rate for suction.
The waste liquid suction device usually uses a vacuum pump to generate negative pressure and sucks the waste liquid into the waste liquid bottle through a suction tube. After the vacuum pump is started, a vacuum environment is formed inside the suction tube, and the external atmospheric pressure presses the waste liquid into the suction tube, which then flows into the waste liquid bottle.
Suitable for various stages of the cell experiment process, such as medium replacement, collection of waste liquid after drug treatment, etc., it can be connected to a disposable pipette to achieve aseptic operation.
Product Features
Safety protection: It has multiple safety protection measures, such as a floating ball anti overflow protection device, which can prevent waste liquid from overflowing and being sucked into the host. Some parts are also equipped with dual overflow protection, with a filter installed between the waste liquid bottle and the vacuum pump to further ensure equipment safety.
Space saving: Some waste liquid suction devices adopt an integrated design, integrating vacuum sources, waste liquid bottles, and waste liquid suction kits, saving space compared to traditional self-organized systems.
Sterilizable: Waste liquid bottles and some suction accessories can usually be sterilized under high temperature and high pressure, making it easy to maintain equipment cleanliness and meet the hygiene requirements of different experimental scenarios.
Safety and hygiene
Immediately clean the pipette head and tubing after use to avoid residual waste liquid crystallization or corrosion of components.
When dealing with biological or hazardous waste liquids, it is necessary to seal the waste liquid bottle and dispose of it according to laboratory regulations.
