[product advantage] Purity: 98% (HPLC), good water solubility, stable process, small batch difference.

There are a few points to pay attention to when using ECL luminescent liquid: 1. When using ECL, the previous steps can be carried out in sunlight, but the sensitivity may be slightly reduced when exposed to strong light for too long. Wearing gloves can avoid leaving fingerprints on the film. 2. If the exposure is too long or the protein is too much, the background will deepen and the band strength will lose the linear relationship, while the underexposure will blur the band. 3. The strips on the membrane glow after incubating for about 1 minute in the luminescent working solution. The strong band luminescence is visible to the naked eye in the darkroom, and the low-abundance protein band luminescence is weak or even invisible to the naked eye, but it can be exposed to X-ray film. The light emission time of the strip cannot be judged by visual observation alone. 4. Too high antibody concentration will cause high background or no bands, which will lead to failure! ECL luminescent fluid is mainly made of luminol, isoluminol or isoluminol derivatives, sodium hydroxide and hydrogen peroxide. Desheng produces luminol and isoluminol raw materials, which need to be matched Lye, hydrogen peroxide, and peroxidase can complete the chemiluminescence experiment.

The foam product is odourless, tasteless, non-pollution and colourstay, so it is very suitable for the foam products which are without smell and with light colour. 2.The product can apply to natural rubber (e.g. EPDM, SBR, CR, FKM, IIR, NBR), synthetic rubber (e.g. PVC, PE, PS, ABS) and thermoplastic products. Its also used for making rubber-resin mixture. 3.The product has fine insulativity and can be used for making wire and cable. 4.In certain situations, it can be used as foaming agent as well as corss-lingking agent in curing mechanism 5.This product is the most commonly used foaming agent. It can play its role with other foaming agent. As its wide use, OBSH is also known as universal foaming agent.   Check-Point Unit Specifications Appearance -- White Powder Purity % min 98 Water % max 0.5 Dec.Temp (5°C/min In Air) °C 152-162 Gas Volume In Air ml/g 125

The Use of EDTA Performance of EDTA anticoagulant tube Steady roof EDTA anticoagulant tube vacuum blood vessel collection, blood vessel collection, disposable vacuum blood vessel collection, EDTA anticoagulant tube 1. Use of EDTA anticoagulant tube for vacuum blood vessel collection: It is used for clinical hematology test and suitable for various types of blood cell analysis. The inner wall of the blood vessel was sprayed with anti-hanging agents, and anticoagulant was added at the same time. EDTA anticoagulant has little effect on the agglutination of blood cells and cell morphology, and can inhibit platelet aggregation. Vascular harvesting is widely used in clinical hematology examination and suitable for various blood cell analyzers. It provides a comprehensive and meticulous protection scheme for blood cells, especially the use of biomimetic membrane treatment technology to effectively prevent platelet aggregation and activation, prevent coagulation, and protect the shape and volume of blood cells in a longer period of time. EDTA anticoagulant tube 2. Specification and characteristics of disposable vacuum blood collection: color standard: purple specification: 12 *75 mm 12 *100 mm routine blood collection: 2 ml 3 ml 4 ml 5 ml additives: EDTA-K2, EDTA-K3 operating environment temperature: 0-37 C material: glass maximum vacuum error (+10%). 3. Notices for vacuum blood vessel harvesting: 1. Immediately after blood collection, 180 degrees were gently inverted and blended for 5-6 times. 2. When collecting blood, please take enough blood to ensure the accuracy of the test results. 3. Remaining vacuum in the tube should be cleared if the blood collection can not reach the prescribed amount.
