Vacuum pump application range, purchase and maintenance for cell house
Cell rooms generally need to be equipped with a laboratory vacuum pump as a necessary basic equipment. The vacuum pump used in the cell house mainly has two types of uses: one is to waste the cell culture medium, and the other is to filter the purchased medium with the filter bottle group.
When purchasing a vacuum pump used in a cell house, it should be noted that due to the unique use environment of the cell house, there is a high requirement for cleanliness and no water supply, so the conventional water circulation pump or the oil pump cannot be used. In addition, since it is used in a relatively closed room, it should try to pursue a lower noise value, otherwise the noise in the closed room will be more enlarged, which is easy to cause discomfort. At the same time, due to the use in the cell room, the instrument should try to avoid maintenance, otherwise it is very convenient to take it in and out. Therefore, the use of oil-free design vacuum pump is a good choice for use in the cell room. These products can be used by plugging in, no need to connect water source or add pump oil. At the same time, no maintenance work is required for long-term use. Different products can also be selected for different purposes:
Pumping of cell culture waste liquid: Generally, a vacuum pump is used together with a set of liquid suction bottle, liquid suction head and foot switch. In addition to purchasing the pump, the customer also needs to buy the relevant accessories to perform the aspiration operation. Of course, customers of this type can also choose a fully equipped laboratory cell waste liquid suction device, such as BV240A model, standard 3000ml large capacity liquid suction bottle, which can reduce the number of waste liquid dumping; standard foot switch Customers can avoid the use of gloved hands to control the switch on the host interface to avoid contamination; with a single channel and 8 different suction heads, convenient for 96-well plates, petri dishes or deeper culture bottles It is highly suitable for aspirating in different containers.
Medium sterilization filtration: generally used by an oil-free vacuum pump with a filter bottle set. Special attention should be paid to the selection of filter bottles. The traditional flask type filter bottle set is not suitable for this type of application, because the filtrate needs to be poured out after the end of the filtration, and it is easy to cause pollution due to inconvenient operation. A professional medium sterilization filter device such as the R300-500 model should be selected. In addition to the standard oil-free vacuum pump, it also includes a bottle-top filter funnel that can be directly connected to the blue cap reagent bottle. After the filtration is finished, the filtrate directly enters the reagent bottle, so that the bottle cap can be directly screwed for storage.
When using a vacuum pump for aspiration and filtration in the cell room, special care must be taken to prevent the suction of the waste liquid. The waste liquid is sucked into the vacuum pump, which may cause damage to the instrument and increase unnecessary trouble. Maintenance may also delay normal experimental work. It is recommended to use anti-back suction accessories such as buffer bottles or water-blocking filters, which have excellent effects.
