Shanxi's external power supply reached more than 60 billion kWh, a record high

According to the Shanxi Electric Power Company, with the 1000 kV Jindongnan-Nanyang-Jingmen UHV AC test demonstration project officially put into operation, the Shanxi “Nortel South Transmission” high-speed channel was opened. In 2009, Shanxi delivered 60.127 billion kilowatts of electricity. At the time, it increased by 16.87% over the previous year, a record high.
Affected by UHV transmission, Shanxi's power transmission capacity has achieved a historic breakthrough, and Shanxi Electric Power Grid has become one of the nation's highest level of technology, transportation capacity and operation capacity, and further expands the power market and expands transmission scale in Shanxi. Accelerate the construction of national new energy and industrial bases and provide a more solid grid support.
The realization of “Nortel Power Transmission” through UHV power grid not only effectively alleviated the situation of power shortage in the south, but also opened up a new way of energy transportation in Shanxi, which provided an opportunity for the transformation and development of Shanxi and accelerated the energy-saving province of Shanxi to energy. The transformation and leap of strong provinces. At the same time, the UHV grid has further optimized the resource allocation of Shanxi Province and promoted the development of low-carbon economy.
 

Centrifuge Tube Rack

At present, in the process of isolation and preparation of various stem cells from various tissue sources, Centrifuge Tubes with a volume of 15ml and 50ml are used.
It is one of the low-value consumables with high usage rate. It is generally installed on a dry foam rack with the package or in bulk. When used, it is taken out by the operator and placed on the plastic centrifuge tube rack in the ultra-clean workbench. The common centrifuge tube rack can only make the centrifuge tube stand upright. When transferring liquid or needing centrifugation, the operator should hold the centrifuge tube in the left and the night gun or aspirator in the right. If it is necessary to transfer a large amount of liquid reagents or perform gradient centrifugation operations, such as density gradient centrifugation to separate mononuclear cells, the operator needs to hold the centrifuge tube with the right hand for a long time and tilt the centrifuge tube, which often causes the operator's wrist joint pain. At the same time, it will also affect the liquid superposition effect, which will easily lead to the mixing of liquids of different densities, resulting in the failure of the experiment.
