Buffer solution is a type of buffer system dedicated to life science research. In biochemical experiments, buffer solution plays an indispensable role. It can resist the influence of a small amount of strong acid and alkali from the outside, and maintain the system closest to the physiological environment. pH value. Both HEPES and PIPES buffers are commonly used buffers in biological experiments. The pH buffer range of HEPES is 6.8-8.2. It is a zwitterionic biological buffer. It is soluble in water and does not form stable complexes with metal ions. In most cases, it will not interfere with biochemical processes and can be widely used in a variety of Biochemical reactions and used as buffer reagents in certain cell culture media. HEPES is often used in the cell culture medium of various types of organisms; in protein research, PIPES is often used as the component and eluent of the binding buffer in cation exchange chromatography; in DNA research, PIPES is used as calcium phosphate and DNA The buffer for the precipitation formation system, AFM and the buffer for electroporation experiments. In addition, HEPES interferes with the reaction between DNA and restriction enzymes, and is not suitable for Lowry's method to determine protein content. HEPES buffer is often used in the research of organelles and highly variable, pH-sensitive proteins and enzymes, as well as in biochemical diagnostic kits, DNA/RNA extraction kits and PCR diagnostic kits. It is a hydrogen ion buffer that can control a constant pH range for a long time. The final concentration is 10-50mmol/L, and the buffering capacity can be achieved when the culture medium contains 20mmol/L HEPES. The pH buffer range of PIPES is 6.1-7.5, insoluble in water, soluble in NaOH aqueous solution. PIPES is different from buffers containing two (2-hydroxyethyl) amino groups (such as Bis-tris, Bicine), and can not form stable complexes with most metal ions. It is suitable for buffers in solution systems containing metal ions. According to existing research results, PIPES can be used to purify tubulin using phosphocellulose chromatography, to purify recombinant GTP-binding proteins ARF1 and ARF2 by gel filtration, and to use as a buffer to crystallize transketolase from E. coli. In addition, because PIPES can form free radicals, it is not suitable for redox systems. In cation exchange chromatography, a low concentration of PIPES buffer should be used, because PIPES has a relatively large ionic strength and its pKa value is concentration-dependent. We must learn to distinguish between the similarities and differences in these reagents, so as to better promote the development and production of our different products. Desheng unanimously adheres to this kind of subtle difference, so that it can continue to develop and produce better products.
Automotive and mechanical structure pipe is one kind of seamless steel pipe for general structure and mechanical structure. Structural pipe standard is applicable to seamless steel pipe for general structure and mechanical structure, and fluid seamless steel pipe standard is applicable to general seamless steel pipe for conveying fluid. The main difference between fluid seamless steel pipe and structural seamless steel pipe is that the fluid seamless steel pipe carry out hydraulic test or ultrasonic, eddy current and magnetic flux leakage inspection piece by piece. Therefore, in the pressure piping standards, it is not suitable to use fluid seamless steel pipe. Seamless steel structure pipe is mainly used in mechanical processing, coal mine, hydraulic purpose, etc. The applicable standards for seamless structure pipe mainly consist of: GB/T8162---------China National Standard ASTMA519-------American Society for Testing and Materials Standards EN10297-1--------EU standards JISG3445----------Japanese Industrial Standards Purpose: Applicable to the general structure, mechanical structure and car structure. � The main production steel grades: 10, 20, 35, 45, 16Mn, 1020, 1045, 1541, E275, E315, 34CrMo4, 42CrMo4, STKM13A, STKM13B Advantages of us 1.Annual supply order and partial shipment accepted. 2.14years production mill ensure you the high quality and considerate service. 3.Free sample is available for testing of goods quality. 4.Both stocks and production order supply style making sure soonest delivery time.

High quality MILD STEEL OXYGEN LANCE manufactuer,send inquiry to us now freely. Thermal lance also known as burning bar or thermic lance, made by hollow mild steel pipes filled with a number of iron wires, which is a powerful efficient cutting tool by high purity oxygen flow through the interior of the lance to create extraordinarily high temperature from 3,600 to 4,426�°C for cutting through just about anything. Thermal lance can be used whenever some ferrous and non-ferrous materials must be removed or cut into pieces, like sand casting riser cutting or ladle furnace tapping. When molten material is spilled, it can be allowed to solidify and then cleaned up with thermal lance. For coastal buildings, interior concrete sometimes breaks down to produce what is called concrete cancer, but thermal lance can be used to remove this degrading concrete so that replacement material can be packed in. These characteristics of the thermal lance make it a particularly efficient and cost-effective method of cutting steel and cast-iron materials too thick to be cut with a normal oxy-acetylene torch. In the case of thicker materials, during the operation, the lance tube will be consumed by the intense heat at the cut point and should be discarded once it becomes too short to be safely used.
