cryo tube with internal cap
If we need to pinch the stopwatch with our eyes and hands one by one, people will soon be slumped, and we can't draw a picture. This step is telling the lab mouse: Don't mess around, it's the last word to get on stage. Water supply and drainage must be considered. Fortunately, the temperature control requirements are not high, otherwise it will be embarrassing.
What is easy to use? To paraphrase Grandpa Deng's famous saying: No matter the white cat or the black cat, a good cat can catch mice. If this step is repeated, the original memory of the experimental mouse will fade and prepare for the next experiment. The smallest diameter for mice is 0. This is not very different from the experimental mice, which are all close-up identifications. Of course, in principle, the ratio of the platform diameter to the water basin diameter affects the difficulty of the experimental task, but usually people are more concerned about the diameter of the water basin.5-2cm), and it needs to be able to change position.2
The requirements for water temperature control are not rigid, because in many cases the water temperature (20-27C) required for the experiment is very close to the room temperature, so just leave a basin of water overnight. In many cases, there are differences in this step, and the speed and quality of acquisition are already a good indicator. Don't underestimate this basin of water, it's just one ton easily. But don't worry, all currently marketed products can easily meet this requirement. For laboratory mice, the smaller the pot, the easier the task, and the bigger and more difficult it is.
In addition to cryo tube with internal cap the position of the experimental mouse into the water, it may need to be repeated for several days. The experience of BB-8 has told us that sometimes this thing is higher than the water surface, sometimes lower than the water surface (usually 0. ), but that鈥too much trouble, so at present, water basins of neutral colors (such as blue, gray) are generally provided to suit various colors of laboratory mice. The more carefully you 'catch', the better! Judging in this regard is actually very easy. The most critical difference is that the position of the station is changed.1 meter large basin, but the depth was only 40 centimeters. This head doesn't open well, so until now there is no certain rule about the size of the basin

When used in a vacuum drying oven, please pay attention: please open the vacuum valve of the vacuum drying oven, start the vacuum pump to vacuum the drying oven, and then start the vacuum drying oven to heat up after reaching the required vacuum. If you really need to pump high-temperature gas for a long time, it is recommended to add a cold trap in front of the vacuum pump to reduce the temperature of the gas drawn into the vacuum pump.

Some customers who need to cryo rack the cell culture supernatant in the clean room of the cell room cannot use this type of product. Whether the use environment needs to ensure that there is no pollution: part Due to the design principles of vacuum pumps, other media are required to assist the operation of the pump, such as oil rotary vane vacuum pumps and water circulation vacuum pumps, which need to pour pump oil and connect water respectively. For example, the vacuum control valve has a very important role for many purposes.How to choose the vacuum pump used in the laboratory is a problem that plagues many users. For example, when matching with a 2000-5000ml filter bottle or a triple filter, you can choose R400, with a pumping speed of 34L/Min; 5L-10L A filter bottle or a six-line filter requires R600 with a pumping speed of 60L/Min or more.
When the pump oil is in use, the oil mist will be emitted into the air, polluting the environment; and the pump must be connected to the water source at the side of the sink. At this time, you should choose an oil-free vacuum pump, which can be used after plugging in. 2. 3. However, when a large-volume vacuum filter bottle or multiple filter is used, such as a filter bottle of 5000ml or more, a triple filter, and a six filter, the filtration speed will be greatly reduced.
It is a very useful accessory, such as BS-02250 water blocking filter with built-in drain With a high-performance filter membrane, air can pass, but 100% liquid cannot pass, which can completely solve the problem of suction. It can be used as long as it has an ordinary 220V power supply. Can meet the needs. When purchasing a vacuum pump, you should pay attention to directly configure the necessary accessories according to different applications. The volume of the matching equipment:
The volume of the equipment is related to the pumping speed parameters of the vacuum pump. It is necessary to investigate the filtrate capacity of the filtration, the content of particulate matter in the liquid, and then choose the appropriate vacuum or pumping speed product according to different situations. The general user may not be able to figure out the relationship between the various parameters of the vacuum pump and the actual use effect. When performing vacuum filtration, the anti-suction accessories set, including buffer bottles and water blocking filters, will effectively avoid the problem of suction damage to the vacuum pump. 4

The configuration of ordinary instruments and equipment is closely related to the division of laboratories. With acid and alkali resistance, impact resistance, heat resistance, economic and durable.
The circuit design must consider the size of the overall power, three-phase power requirements, and the requirements of the stability of special instruments. The focus of the ventilation system is the determination of the location of the air inlet and outlet and the embedding of the air outlet. . There are still many gaps in the construction of modern laboratory in theory and practice. (4) Corrosion-resistant physical and chemical veneer: it is made of kraft paper impregnated with phenolic resin, white and special surface paper with high temperature and high pressure.
At present, there is no national standard to regulate and require laboratory hardware construction in my country. (4) Glassware drying and storage cabinets: Washed off-the-get off work containers are stored on the brackets. (1) Sample cabinet: A sample cabinet for placing various types of experimental samples should have a partition that can be labeled and labeled to facilitate storage of samples and search for samples, because some samples are required according to the physical properties and chemical stability of the samples Put it in a desiccator for storage, so the compartments are large and small to facilitate storage of different samples. Layout Mode The focus of the experiment table layout is safety and convenience.
In addition to the type of ground, pay attention to the 10ul Filter Tip of the upper and lower water pipes., a highly reliable, sterile, and dust-free environment is essential. At the same time, the construction of the suspended ceiling should also be considered in synchronization with the facilities of the ventilation system. Often used in large spaces and rectangular indoor forms. Marble floors cannot be used in laboratories. In the biological laboratory, the special requirements of data processing workflows for inspection, testing, photographing, and washing are generally considered, and a washing station and a drying station can usually be provided at the entrance.
Megosztás a facebookonLaboratory glassware is cleaned by hand. The cleanliness of the cleaning is not repeatable, which may affect the authenticity of the experimental data. 3. The laboratory glassware is cleaned by hand, and the experimenters are in direct contact with various chemical cleaning agents, strong acids, strong bases, chromic acids, etc., which may harm the physical health of the experimenters and physical harm. In particular, the harm of hexavalent chromium to the body is irreversible. 4.
It's not simple, just look at how many injection heads there are. Good production enterprises have more semi-injection baskets and insert racks to meet a wider range of cleaning requirements. 2) Heating method and temperature control system: A: heating method: there are two methods of integrated heating of the circulation pump and the separation of the circulation pump and the heating wire. Different heating methods directly affect the length of cleaning time.
The integrated heating of the circulation pump has high efficiency. Greatly shorten the cleaning time. B: Temperature control: Whether the temperature control is accurate. A good temperature control will be controlled within 1 degree range. A bad temperature control is often extensive, with large fluctuations up and down. Contaminants that are more precise or sensitive to temperature cannot be cleaned. Or if the cleaning is not clean (such as protein, etc.), the effect of different batches of cleaning will not be guaranteed. 3) Operation monitoring system and filtration system: with or without rotating arm operation monitoring system and water pressure monitoring system, without monitoring may result in unclean cleaning when the rotating arm does not rotate or the circulation pump is blocked and the pressure becomes small.
Good products have sophisticated four-layer filtration systems. At the same time, it guarantees the minimum wear on the measuring tool and significantly prolongs the service life of the measuring tool. 4) Waterproof system: Some manufacturers have written on their color pages that they have a waterproof system, but not necessarily a real waterproof system. A good waterproof system is that when there is no one on duty, in case of water leakage, it will automatically close the water inlet line, automatically open the drain valve to drain, and the equipment will stop running.
