Earlier, it was reported that Apple had invested nearly $500 million to purchase a large number of sapphire-making boilers for the new plant in Arizona. At the same time, cooperation with GT Advanced began.
The previous news also revealed that Apple and GT have signed a cooperation agreement for many years. Today, Canonical CEO Mark Shuttleworth reveals that Apple has purchased enough sapphire screens for three years. Shuttleworth said in an interview: "Apple recently purchased a sapphire screen that is available for three years, which is the screen we intend to use on the Edge of the first Ubuntu system phone."
At the beginning of the month, Apple reported that the material purchased for the Mesa plant was enough to produce hundreds of millions of 5-inch sapphire screens. Both Bloomberg and The Wall Street Journal reported that Apple will launch two screen-sized iPhones this year, 4.7 inches and 5.5 inches, each with sapphire glass.
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.
