The liquefaction of culture fluid in the cell compartment is an operation often performed in many laboratories. The operator needs to use a special cell waste aspirator to push the pipette into the biosafety cabinet or the clean bench to aspirate the cell culture fluid. There are many types of laboratory suction pump products available on the market, and there are many differences in the design, structure, and attachment configuration. Some may be suitable for the suction of residual liquid after general experiment, such as centrifuge tubes or The residual liquid in the 96-well plate is sucked, and some are used for the suction of organic solvents. So what are the differences between the products that need to be used in the cell room clean bench and the biosafety cabinet?
The supernatant in the cell room can only be pumped with oil-free waste liquid without contamination.
(The picture above is from left to right: BV225A, BV24A)
First of all, the product that needs to enter the cell room clean room should be equipped with an oil-free design pump, which can not cause any pollution to the environment or the use place. Traditional water pumps and oil pumps cannot meet this need.
As shown above, the L100BS aspiration pump is small and lightweight, preventing it from being used in a clean bench or a safety cabinet.
Secondly, some customers may prefer to place the entire aspiration pump in a clean bench or a biosafety cabinet when pumping cell waste. This makes it easier to handle. At this time, it is necessary to consider the overall dimensions of the machine. Weight, if the size is too large, there is no way to put it in. If the weight is too heavy, it may exceed the maximum load on the table to cause unnecessary safety risks. Such as L100BS small waste liquid suction device, the outer dimensions are only: 265 × 130 × 210mm, the weight is. 3 kg, light and compact, with a handheld operator, a single-channel retractable tip, 8 tips, can be placed directly in the ultra-clean platform and bio-safety cabinet.
Third, you need to consider the way the machine sucks and stops control. Users who use cell attractor products in clean rooms are required to carry gloves. Many times the instruments are placed on the floor below the clean bench and the biosafety cabinet. The pipettes and tips are extended to the operating area for suction. Liquid, if you use a gloved hand to control the power switch on the surface of the instrument to control the suction, it is neither convenient nor contaminated. At this time, other auxiliary accessories are needed to help the experimenter control the machine to stop. For example, a hand-held operator that connects the tips, or a foot switch that is controlled by the foot.
The handheld operator can directly control the liquid suction and avoid using the switch on the panel.
For some customers who have purchased aspiration pump products, the BS-KH handheld operator can be selected with a suction stop control switch. It can be connected to a pipette and a disposable tip. At the same time, the accessory has a strong adaptability and can be used in conjunction with other brand attractors.
The picture on the left is the BV240, which is controlled using a foot switch;
The picture on the right shows the BV240A, and the foot switch and hand-held operator can be used to control the suction.
Customers who purchase laboratory waste suctioners for the first time can purchase products with foot switches directly, such as the best-selling cell waste pumping system BV240, which comes standard with a foot switch that can be used to control the suction of waste liquid.
As shown in the figure, the sterilization of waste bottles is a basic requirement for aspiration products used in cell houses.
Fourth, the sterilization method. Generally, ordinary liquid absorbing customers do not have special cleaning and sterilizing requirements for the tips, suction nozzles, and waste liquid bottles, but they can be washed with water after use. Products used in cell houses must be sterilized and special attention must be paid to sterilization. The conventional scientifictool cell waste liquid suction system is equipped with a liquid collection bottle that can be autoclaved. Some other customers prefer to use direct disinfection with sterile water, which requires the use of all-glass waste bottles.
