Recently, as a non-renewable strategic scarce resource, copper's market price will continue to grow with the large amount of demand caused by the rapid development of a large number of developing countries. Therefore, the recycling and fine application of copper has increasingly become the basis of modern industry. A focus of attention. The recent two years of changes in copper prices have fully demonstrated this trend.
At present, the price of non-ferrous metals has skyrocketed, and the cost of copper conductors has accounted for the large cost of busbars for distribution equipment. In order to ensure that the technical specifications of the conductor can be met and the cost of the conductor can be significantly reduced, our company adopts a copper-clad aluminum row product produced by hydrostatic extrusion technology to completely replace the conductivity of pure copper. Of course, this kind of material has been applied in Europe for several decades. The large international companies such as ABB Siemens, etc., have used it extensively as a strategic reserve for technology and have included it in their product specification books as early as possible.
1. Good corrosion resistance: Under normal conditions, aluminum is more easily corrosive than copper, but due to the aluminum in the copper-clad aluminum row, it is completely covered with copper, which improves the oxidizing properties of the aluminum conductor.
2. Aluminum in the contact point is prone to potential corrosion, contact resistance is large, copper clad aluminum row through the composite technology to solve the potential corrosion, with copper-like surface contact performance.
3. Copper clad aluminum conductive strips are lightweight, easy to process, and easy to install and transport. Copper-clad aluminum conductive strip has the advantages of relatively low cost and relatively stable price, which overcomes the disadvantages of high cost and large price fluctuations of copper strips. It is assumed that the original conductive row is 100×10. The inspection manual can know that its current carrying capacity is 1860A. The data copper conductive aluminum conductivity is 90% IACS. In order to be safe, the cross-sectional area of ​​the copper-clad aluminum conductive row can be increased by about 15%, and a 100×12 copper-clad aluminum conductive row can be used.
Eppendorf tip refill is designed, developed and produced to perfectly match most brands of pipettes. The refill tower tip is suitable for most brands of pipetting systems to ensure pipetting accuracy. The sterile refill tower Pipette tip uses medical-grade plastic packaging to protect the Pipette Tips from contamination. The pipette tip refill is sterile, free of DNA, DNase, RNase, endotoxin or ATP. It can be autoclaved at 121 °C/250 °F (2bar) and sterilized by heat and humidity, in accordance with DIN EN 285. Environmentally friendly packaging. According to the IVD Directive 98/79, it has the European Union CE mark.
Compared with ordinary carton packaging, the refill tips system can save 60% of laboratory space and 70% of plastic. Without touching the tips, you can refill the shelf with one hand. Refill Pipette Tips can be used with universal carrier boxes.
