Analysis of sterilization method of cell house waste liquid suction vacuum pump

The laboratory cell room waste liquid suction vacuum pump generally needs to be sterilized after use, otherwise it will easily cause cross contamination and eventually affect the experiment. But which parts need to be sterilized, which parts can be sterilized, how to sterilize, and how often each bacterium often makes a lot of customers lack understanding. Some customers even purchased similar products in the field of civil medical use, and finally found that the components of similar products for civilian medical treatment could not be sterilized normally, which affected the overall use and increased the cost of later purchase.
First of all, we need to understand why the cell chamber waste liquid used in the laboratory is required to sterilize the vacuum pump , and the medical products cannot be sterilized, which may not be used in the laboratory field. Because the laboratory aspirate products are most commonly used for the supernatant of the culture medium, if the pipes, tips, etc. are not sterilized, the cultured cells will be polluted and cause more damage, so in the design laboratory cell house waste liquid suction vacuum pump The requirement that each contact liquid component must be sterilized is proposed, and the materials used are more different from the non-sterile materials. In general, civilian products only need ordinary cleaning, medical products need to use disposable products, and there is no need for sterilization.
The most common method of sterilization is autoclaving and disinfecting water soaking. If the customer has purchased a professional product at the laboratory level, then other parts besides the main unit must be autoclaved.
For example, BV235, BV225, BV240 are the main hot-selling models. The waste bottle is made of polycarbonate. This material avoids the disadvantage of heavy weight of the glass. It is easy to handle and has a certain impact resistance. At the same time, this material can also withstand the mainstream 121 degree high temperature and high pressure disinfection method, and will not deform or crack under long-term sterilization conditions. In addition, these types of vacuum pump tubes, pipettes, shampoo adapters, water blocking filters and other accessories are also made of high temperature resistant materials, which can be autoclaved.

In addition to the conventional high temperature and high pressure sterilization, some users in the laboratory will also use the method of immersion in disinfection water. This method of sterilization is more convenient and quick, and it is not necessary to take out parts such as waste bottles out of the cell room, directly in the cell room. Prepare disinfectant water to soak the waste bottle. Of course, this method of waste liquid bottle material puts forward higher requirements, and the raw materials of the waste liquid bottle need to use materials with better chemical corrosion resistance. For example, L400BS is made of polyethersulfone, and BV300EG cell house waste vacuum pump is made of all-glass material. Both of these are suitable for direct disinfection.

Water Test Strips 15 Parameters

Detection method:
visual
Operation method:
1. Visual inspection: Immerse the test area of the test paper into the fully stirred fresh drinking water, and take it out immediately;

2. Put the edge of the strip against the edge of the container to remove excess water samples;

3. Compare the test strip with the colorimetric table on the bottle label, and record the test result in the determination time: 0 ~ 60 seconds. Use visual.

Storage conditions:
The test paper should be stored in room temperature, dry environment, away from a variety of chemical reagent environment, avoid direct sunlight. This product does not need to be refrigerated (if it is stored for a long time, it should be restored to room temperature and opened for use).
