1. At this temperature, cell Laboratory Consumables and life activities are almost completely stopped. If the laboratory funds allow, a high-quality phase contrast microscope with a camera system can be configured to photograph and record the situation of cells at any time, which is of great help to the development of scientific research work.
Therefore, it is different from other general experimental work. This environment also needs to be clean and dust-free.8 to 7. (5) The refrigerator cell culture room must be equipped with an ordinary refrigerator or a freezer, and the refrigerator preferably has a low temperature refrigerator (-20 ℃). Prevent frostbite during use. Sterile operation area (1) Sterile operation room: It is only limited to the area of cell culture and other aseptic operations.,
it should be filtered and sterilized on a sterile operating table. In addition, most animal cells need to survive and grow in a slightly alkaline environment, with a pH of 7. (8) The items that the sterilizer directly or indirectly contact with the cells need to be disinfected and sterilized. Special equipment For more efficient, accurate and in-depth research on cell science, qualified (local tyrants) laboratories can add some special, advanced and sophisticated equipment and instruments, such as multifunctional enzyme-linked immunoassay analyzer,

The cell culture laboratory should be able to perform six aspects of work: aseptic operation, incubation, preparation, cleaning, disinfection and sterilization treatment, and storage. Even so, sometimes the temporarily needed items or fragile utensils still need to be sterilized by the cell culture laboratory. It is better for each department to be installed in each connected room, especially the sterile operation room can be set separately; if they are all placed in a large laboratory, the sterile operation area and the cleaning, disinfection and sterilization area should be located at both ends. The size should be appropriate, and the top should not be too high (not more than 2.

In addition, the resistivity value will change with the ionization constant of water, so it will be affected by the temperature of the water. Soluble organic matter: lignin, tannin, humic acid, endotoxin, RNA degrading enzymes, pesticides. are often used to supplement the important parameters of water quality. At present, the most common pure water standards in the world are the following:
International Organization for Standardization (ISO), American Society of Clinical Pathology (CAP) test-grade water standards, American Society for Testing and Materials Experiments (ASTM), International Clinical Test Standards Committee (NCCLS), American Pharmaceutical Association (USP), etc.2MΩ. , Chloroform, environmental hormone substances, surfactants, organic solvents.248MΩ.1μs/cm.
This value is usually called resistivity or specific resistance in water quality analysis, and its unit is expressed in MΩ. These two parameters are the most commonly used parameters indicating the purity of water. Microparticles: rust, colloids, suspended solids, solid particles. Minimalist operation, extreme results, and ultimate experience. For example, the resistance value of ultrapure water at 25°C is 18. It is pre-purified by ion exchange, RO membrane or distillation, and then purified by nuclear-level ion exchange purification. It can be made by a single weakly basic anion exchange resin, reverse osmosis or a single distillation.
and the Plastic Micro Tubes and content of these components determine the taste of the water. Ultrapure water is suitable for a variety of precision analysis experiments, such as high-performance liquid chromatography (HPLC), ion chromatography (IC) and ion trapping-mass spectrometry (ICP-MS). Therefore, the water purity standard is usually comprehensively described and graded by one or several of the above parameters.cm. Because the centers of positive and negative charges are inconsistent, they belong to polar molecules. Ultra-pure water with few heat sources is suitable for biological applications such as eukaryotic cell culture. In the vicinity of 25℃, when the temperature rises by 1℃, its resistance value will drop by 0. Usually the resistivity of ultrapure water can reach 18. Ultra-pure water.

Do not cut and pull the tissue repeatedly, causing tissue compression. 4. Positive expression of cytoplasm and cell membrane, for example, EMA can show membranous and diffuse cytoplasmic positive reactions; CD30 antibody can show both membrane and cytoplasmic spot positive reactions. The antigens we detect are diverse. At this time, a few drops of ethanol can be appropriately added to the water. Soak the detergent powder for 30 minutes, rinse, and dry. With the extension of fixed time, the detection intensity of tissue antigen will gradually decrease. 1)

The failures that may occur in the laboratory ultrapure water machine during use are as follows: Fault 1: The pump of the ultrapure water machine does not start, resulting in inability to make water. The first step: observe whether the alarm indicator on the panel system of the ultrapure water machine will flicker. Yes. Possible cause of failure: low water pressure / abnormal low pressure switch / clogged activated carbon filter. no. Possible cause:
The high-voltage switch is damaged. Fault two: The laboratory ultrapure water machine system has been making water. Possible cause: High pressure switch or check valve failure. Fault three: The water production and water full conversion of the laboratory ultrapure water machine system is too frequent. Possible cause: The pressure bucket switch of the ultrapure water machine is not turned on, and water cannot be stored.
Fault four: The water output of the laboratory products manufacturers is too small. Possible causes of failure: insufficient raw water pressure, blocked PP filter element or reverse osmosis membrane. Fault five: Leakage of the pump head Possible cause: Blockage of the PP filter element or activated carbon filter element / aging of the rubber pad of the pump head or blockage of scale / blockage of wastewater ratio. Fault 6: The pump is running normally but water cannot be generated. Possible cause: The RO membrane is blocked or the waterway is blocked or the pump loses pressure. Seven: The panel water indicator is on and the water cannot be generated. Possible cause: Check whether the pump has 24VDC output to the pump. If yes, the pump is broken or blocked; if no, check whether the line is normal. Fault eight: The power indicator of the booting system does not light up and does not work.
Possible cause: Check the fuse is abnormal or the power switch fails. The choice of laboratory ultrapure water machine, Shanghai Hetai is undoubtedly the first choice. Shanghai Hetai Medium Pilot Series pure water machine / ultrapure water system is an economical choice of primary pure water for daily laboratory, which can meet the routine production process water and experiments. Roomware cleaning water requirements can be used as the water inlet for ultrapure water systems, high-pressure steam sterilizers, environmental test chambers and other instruments.
