II. Introduce products related to new coronary pneumonia

1. A disposable virus sampling tube

The current new coronavirus is an RNA virus. After the samples are collected, incorrect storage or transportation may cause some nucleic acids to degrade and affect the test results. In addition, unactivated virus samples are likely to cause operator and indirect infection. For the laboratory, the safety level is high; and use existing nucleic acid detection kits, professional specimen collection tools should be used.

The single-use virus sampling tube is used for the collection and transportation of clinical influenza, new coronavirus, avian influenza (such as H7N9), hand-foot-mouth virus, measles, and other virus specimens, as well as mycoplasma, ureaplasma and chlamydia specimens. With the launch of new coronavirus detection reagents and general screening, the demand for single-use virus sampling tubes has increased significantly. In response to the production of products in short supply during the epidemic period, the company has increased its personnel into production during the holidays, and it can be supplied in large quantities one after another.

2. One-time blood collection tube for nucleic acid detection

Labtub® disposable blood collection tubes for nucleic acid detection (referred to as "nucleic acid detection tubes") are specially designed and manufactured for nucleic acid detection, mainly used in blood collection and supply institutions (blood stations, blood centers) and hospitals for venous blood samples for nucleic acid detection Collection, transportation, and storage, as well as pre-treatment of specimen analysis, to meet the clinical nucleic acid amplification test and clinical molecular diagnostic test methods to quickly prepare undiluted plasma specimens.

  • It is produced under pure purification conditions, and the possible pollution is minimized during the production process, effectively reducing the impact of possible carry-over pollution on the experiment.
  • The inner wall of the vacuum blood collection tube is treated with DEPC, the finished product is sterilized by Co60 irradiation, and the sterility guarantee level can reach 10-6, which can completely eliminate the effect of RNase on the experiment.
  • The application of unique additive technology will not affect the activity of the Taq enzyme in the nucleic acid detection experiment, and can effectively eliminate the interference of the hemoglobin in the red blood cell on the nucleic acid detection experiment.
