There are many types of centrifuge tubes for laboratory centrifuges. 1, according to the material can be divided: plastic centrifuge tube, glass centrifuge tube and stainless steel centrifuge tube. 2, according to the speed can be divided: low-speed centrifuge tube and high-speed centrifuge tube. 3, according to the capacity can be divided: microcentrifuge tube, small volume centrifuge tube and large volume centrifuge tube. Generally, a centrifuge tube having a capacity greater than 100 mL is a...
The centrifuge tube is mainly made of plastic and stainless steel. The commonly used materials for plastic centrifuge tubes are polypropylene (PP), polyethylene (PE), polycarbonate (PC) and the like. Among them, the performance of PP tube is good. The advantage of plastic centrifuge tube is transparent (or translucent), the hardness is small, the gradient can be taken by puncture method, the defect is easy to deform, the corrosion resistance to organic solvent is poor, the service life is...
Whole blood is divided into non-coagulation and anticoagulation according to the conditions of collection. At the same time, the upper yellow liquid that is not separated by anticoagulation is called serum; the upper yellow liquid separated by anticoagulation is called plasma. The storage temperature and time of the specimen, as the method steps of serum, plasma, and cell separation are also important factors influencing the test results before analysis. After blood is drawn, blood cells need...
How to use the pipette Method 1: Advance pipetting method (applicable to conventional liquid pipetting) 1. Adjust the scale or reading of the sampling gun to the required amount of liquid to be aspirated, and install a suitable pipette tip. 2. Press the button to the first stop position (with obvious blocking feeling) and keep it to squeeze out the air in the suction head to form a negative pressure in the suction head. 3. Immerse the tip into the depth of 2 to 3 mm below the surface of the...
When conducting research on analysis and testing, a pipette is generally used to measure a small amount or a small amount of liquid. Many people will ignore the correct use of the pipette and some details of its operation. Now it will be described in detail in several aspects. Range adjustment When adjusting the range, if you want to adjust from a large volume to a small volume, you can rotate the knob counterclockwise according to the normal adjustment method; but if you want to adjust from a...
What is the difference between disposable medical protective clothing and medical isolation clothing? Medical isolation garments can be used repeatedly to save costs. The structure of protective clothing is characterized by its anti-permeability function, good strength, high strength, and high hydrostatic pressure resistance. It should be mainly used in industrial, electronic, medical, anti-chemical, and anti-bacterial infections in addition to meeting high strength. In addition to wearing...
Rat blood was taken multiple times: Blood extraction from the orbit is a good method. One of the main points is to fix the rat so that the animal cannot be struggling. It is best to ask an experienced teacher for a few more exercises that should be completed. The following is a continuous puncture of the posterior orbital venous plexus of the rat. The puncture site is the posterior orbital venous plexus between the eyeball and the posterior orbital boundary. A special hard glass straw is used,...
Prefilled syringes are not a new technology. Most of the previous applications are widely used in the application fields of insulin and human growth hormone. It has several outstanding advantages: no cross-infection during use, convenient use by medical staff, full use of some advanced drugs, no residual liquid, and suitable for self-injection on site. Prefilled syringes are used in a wide variety of applications such as multiple sclerosis, infertility, osteoporosis, hepatitis, rheumatoid...

Chinese Academy of Sciences Polyvinyl chloride (PVC) is one of the main varieties of general-purpose plastics. PVC plasticized with phthalic acid (diethyl) hexyl ester (DEHP) is widely used for one-off production. Medical infusion devices, such as disposable infusion sets, blood bags, hemodialysis lines, etc. However, with the extensive and deep clinical application and the development of related medical science and technology, people have found that PVC materials have hidden dangers in safety....
PRP contains fibronectin and fibronectin. Fibronectin is a macromolecular glycoprotein that has a variety of biological activities. It can promote the adhesion growth of cells, and the adhesion of cells is a necessary condition for the maintenance of the body structure and the completion of cell growth. It also facilitates the migration and proliferation of epithelial cells to repair wounds, and can also play a positive role in improving peripheral blood vessels and lung function. Based on...
PRP treatment PRP treatment refers to the surgical procedure of applying or injecting PRP, that is, taking PRP derived from itself and injecting into skin tissue. The abundant growth factors in PRP stimulate muscle cells, increase skin collagen and elastic fibers, repair damaged skin and rejuvenate skin. PRP treatment does not use artificial chemicals, and there is no trace after surgery. Advantages of PRP therapy easy to use It takes only about 10 minutes to complete the entire operation and...

First, identify the five criteria for qualified vacuum blood collection tubes 1. Aspirating volume experiment: the suction volume, that is, the amount of blood drawn, within ±10% of the error, otherwise it is unqualified. The inability to draw blood is the main problem that currently exists. This not only causes inaccurate inspection results, but also causes blockage and damage of the inspection instrument. 2. Container leakage test: The vacuum blood collection tube containing the sodium...
