The laboratory waste liquid aspirator is a basic instrument commonly used in biological laboratories. It is mainly used to pump the residual liquid after various experiments, including the waste liquid of cell culture medium, the supernatant after centrifugation in the centrifuge tube, and the 96-well plate. Residual liquid and so on. In order to meet the special aspiration requirements of the laboratory, many laboratories are equipped with professional laboratory waste suction devices. However, some customers will purchase civilian or medical suction products for price reasons and take them to the laboratory for use. Since civilian products generally have the characteristics of large output and relatively low requirements for use, medical products are often used at a lower cost than the ones that are relatively inexpensive but easy to replace due to their particularity. Therefore, the cost and final price are often lower than the professional experiments. Room product. However, after using the suction products of civilian or medical use, this part of the customer often has such problems. For example, if the waste liquid bottle is sterilized several times, the deformation cannot be used, and the liquid is easily sucked into the pump. The following is a brief analysis of the specificities of laboratory aspirating products, which are irreplaceable in other areas: As shown in the figure, the laboratory waste suction device often matches a variety of different liquid suction heads. The picture on the left is BV225A and the picture on the right is L400BS. As shown, they are equipped with a set of pipette kits that can be used for liquid suction in different containers. Professional laboratory waste liquid aspirator will generally be equipped with these different types of liquid suction head according to different needs of customers. For example, L400BS waste liquid suction device is equipped with a full range of suction heads, which can meet all the liquid absorption requirements of the laboratory. The waste bottle of the laboratory aspirator is made of high temperature and autoclave material. BV300EG waste liquid suction device is equipped with all-glass waste liquid bottle, which can be directly disinfected with disinfectant water. For example, BV225, BV235 and BV240 waste liquid suction devices are all waste liquid bottles made of polycarbonate materials, which can be repeatedly autoclaved. In addition, in order to save the sterilization time, some customers use the method of directly sucking the disinfectant water into the waste liquid bottle to sterilize. The disinfectant water is highly corrosive, and the material of the waste liquid bottle is required to be higher. The BV300EG and L400BS models are used together. The liquid bottle is excellent in material and has excellent chemical resistance. It can directly pump disinfectant water. 3. Placed in the cell room clean room use: Cell culture fluid waste liquid extraction is one of the longest applications involved in laboratory aspiration pumps, and such customers often place the instrument in the cell room. The clean room generally needs to be sterilized by regular UV lamp, and the suction device placed in the clean room of the cell room will also be exposed to ultraviolet light. Some customers will purchase very small products directly in the clean bench and biosafety cabinet, and will also be sterilized by UV light. The instrument is easily exposed to ultraviolet light for a long time, and the failure rate is improved. For this special use environment, the professional cell culture medium suction system will take into account such problems in the design of materials and components. 4. Control method: The suction of the cell culture medium waste liquid often needs to place the instrument under the ultra-clean table and the biological safety cabinet. At this time, the tester's hands with the gloves are not suitable for pressing the host interface switch. More diverse control methods are needed to operate the instrument. For example, the BV240 cell culture fluid waste liquid suction system is equipped with a foot switch; the BV225A is equipped with a hand-held operator, and the liquid suction can be controlled by the thumb. The water blocking filter can prevent liquid from sucking up by 100%, and the whole series of waste liquid is standard.

1. The size of the aspirating container is complex and requires different tips. The liquid suction in the laboratory often involves a culture dish, a culture bottle, a 96-well plate or a centrifuge tube. These different containers require different sizes of tips. For example, a typical petri dish can use a single-channel tip with a 200 μl disposable tip. The flask is used for a deeper 1000 μl gun tip or even Long stainless steel tip, 8-channel tip with disposable tip (Cat. No. BS-K-8EJ) is suitable for 96-well plates, long stainless steel needle tips (Cat. No. BS-K-84) 96-well deep well plate. Some tests involve pathogenic viruses, and often do not use the hand to pull the tip. You need to use a liquid suction head (BS-K1-EJ) with automatic tipping function. 
2. The waste bottle must be sterilized. Many consumer product attractors are generally used for sucking, and there is no sterilization requirement for waste bottles. Medical aspirator is used for surgery, amniotic fluid attraction, etc. Because of the special use of disposable materials, there are more waste bottles. If you only look at a single waste bottle, the price may be cheaper, but it is very high because of the one-time long-term use cost. However, due to the special nature of the medical industry, disposable products must be used. Laboratory waste extraction generally requires sterilization, but in view of long-term costs, waste bottles that can be repeatedly sterilized are generally used. 
5. Anti-waste liquid suction: The liquid is directly sucked into the pump and damaged. The instrument is the most common fault of such products. The reason for this problem is very similar. As mentioned above, because the laboratory uses the product many times on the ground, the biosafety cabinet or the underside of the clean bench, it is not conducive to observing the liquid level of the waste bottle. In addition, many university research institute laboratory operators have complex and diverse structures that cannot be effectively controlled. Medical institutions are responsible for the dumping of waste liquids, and the maintenance system of the equipment is perfect. Many civilian products only need to consider dust prevention, and the use of personnel is relatively simple, and it is easy to observe the liquid level of the waste liquid bottle. Therefore, the general civilian suction device only matches the dust-proof filter. Once the instrument inhales the liquid, the maintenance time and money cost are very high. Can not meet the needs of the laboratory. The full range of Sciencetool laboratory waste suction devices are equipped with water-blocking filters. The built-in PTFE hydrophobic membrane can block 100% liquid filtration membrane and completely solve the problem of back suction.
