A few years ago, Hyundai used RFID technology in the field of car theft. Now, Hyundai Motor Company no longer uses the traditional bar code management mode, and continues to apply RFID to the logistics supply chain, using passive ultra-high The frequency RFID tag (Class 1 Gen 2, manufacturer - UPM Raflatac) manages the supply chain services of the logistics company Glovis (headquartered in Seoul, South Korea).
In the first phase of the RFID implementation project, Glovis will attach UPM Raflatac's UHF RFID tag "DogBone" to the corrugated cardboard boxes and boxes that package auto parts, with a total of 130,000 labels. Glovis will ship RFID-tagged boxes to the modern car assembly plant in Alabama.
In the second phase, Glovis will track the labeled boxes and containers that are shipped from headquarters to the world. The RFID tags will be used in 20 million units annually.
With the help of RFID tags, modern logistics companies can track and monitor the operation of all links and steps in the logistics supply chain, and collect data in real time: including transportation to the Glovis distribution center, re-packing, and delivery from the distribution center. The link to the distribution center in Costa Mesa, California, and Montgomery, Alabama, and finally to the Montgomery assembly plant (HMMA, which produces Sonata and Hyundai-Santa Fe models). The annual output value is more than 1.1 billion US dollars).
Research firm ABI Research believes that automakers can benefit from RFID technology applications, particularly in logistics supply chain tracking and assembly lines. At present, several major automakers have applied RFID technology. For example, HUM's Honda Automotive Manufacturing Headquarters (Honda) applied UHF RFID tags to track auto parts shipped to the Swindon Assembly Center in the UK. In addition, Honda's subsidiaries in Italy have also attached passive high-frequency RFID tags on the chassis and parts of the car (including speed machines and engines) to collect relevant information on the assembly line.
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.
