The cell waste liquid suction vacuum pump is a basic equipment that the biological laboratory must use in the clean room. The instrument is mainly composed of an oil-free aspiration pump, a waste liquid collection bottle, a liquid suction head and a pipette. composition. In addition, some accessories such as buffer bottles, vacuum regulators, foot switches, 8-channel tips, etc., need to be selected according to different customer requirements and operating habits.
The waste liquid extraction under the St. Stephen's Sciencetool brand is subdivided into more than a dozen models according to the configuration. Customers often choose not to start with many models. Generally speaking, the main differences between different models of cell waste suction devices include the following aspects. :
1. Vacuum and pumping rate: This is the core parameter of this instrument. The vacuum and pumping speed will determine the actual speed of suction and aspiration.
2. Dispensing bottle configuration: The capacity and quantity of the waste bottle will determine the total amount of waste liquid. In addition to the difference in capacity, the amount of waste liquid bottle is also an important parameter. The BV235 model has a dual waste bottle design. The waste bottle near the vacuum pump can be used to hold waste liquid or as a buffer bottle to prevent back suction.
BV240 waste suction device - with foot switch and hand-held operator, 3 suction control modes
3. Control method of suction and stop: Since the cell waste liquid suction pump is used in the clean room cell room, the user needs to wear gloves when operating, and at this time, if the power switch is still controlled by the main panel, the machine starts and stops. It will contaminate the gloves. Therefore, the professional cell waste liquid attracting products will provide different control methods, such as St. Stephen's BV240A. This model can use the foot switch and the handheld operator to control the suction of the liquid.
4. Dispensing head configuration: This requires the user to choose according to the culture vessel used by himself. If it is a deeper culture flask, long-length stainless steel suction needle (order number: BS-K-18) can be used for 96. The 8-well tip (BS-K-8EJ) can be used for the well culture plate, and the basic single-channel tip (BS-K-1) can be used for the general culture dish.
The L100BS is a lightweight, small-sized aspiration pump that can be used directly in a clean bench and biosafety cabinet.
5. The composition of the waste liquid bottle and the main machine: the basic laboratory waste liquid suction device host and the waste liquid bottle are only connected by the vacuum pump tube, the relative structure is simple, and the cost is high; most models are in the host The side has a fixed bracket, and the waste bottle can be loaded into the bracket. This design has obvious advantages for the movement of the whole machine, and the waste bottle is not easy to dump; the most advanced design is the integrated model, that is There is a fixed seat in the middle of the body, and the waste liquid bottle is directly placed in the fixed seat. In addition to being easy to move and the waste liquid bottle is not easy to be dumped, the occupied space of the countertop is greatly reduced, for example, L100BS, with a lightweight design with a weight of only 1.2KG. It can be used directly inside the biosafety cabinet and the clean bench.
6. Configuration of other accessories: The accessories can make the actual operation easier: for example, vacuum gauges and vacuum regulators can observe the working state of the machine during work, and then adjust the pumping speed according to actual needs; The device can block the liquid 100% and completely solve the problem of the waste liquid suction pump. In general, the attachment configuration of high-end models will be more abundant.
