ZLG Embedded Solutions for Medical Detection and Protection Equipment

Abstract: Detection kits are currently the key method for diagnosing suspected patients. This article introduces the solutions provided by ZLG in key instruments during the development of kits.

The development of virus kits is inseparable from the analysis of medical instruments such as gene amplification instruments (PCR) and fluorescence analyzers. After the successful development of the reagents, three kinds of nasopharyngeal swabs, sputum, and bronchoalveolar lavage fluid of suspected patients are required. sample for testing. The detection of the kit also requires corresponding instruments, including specific protein analyzers, hand-held fluorescence analysis and other medical equipment. Under the needs of a wide range of detection groups, there will be a need for miniaturization of such equipment. In the best case Is to achieve handheld analysis, to achieve point-of-care testing (PCOT).

ZLG’s mature application solutions have been widely used in such equipment. This article will introduce ZLG’s solution in equipment and instruments.

1. Gene Amplifier

Gene Amplifier (PCR) is actually a programmable controllable temperature cycler with rapid temperature change and precise temperature control. It is mainly used for researches such as gene isolation, cloning and nucleic acid sequence analysis. The features of simple operation and time saving play a crucial role in the acquisition of the whole genome sequence of the new coronavirus.
