Since the global outbreak of the COVID-19 pandemic, nucleic acid testing technology, especially the fluorescence quantitative RT-PCR technique, has become a key tool in epidemic prevention and control. This technology accurately captures the unique genetic sequences of viral RNA or DNA, efficiently replicates and labels them in vitro, thereby quickly and accurately determining whether the virus exists in the sample.
PCR testing has not only successfully assisted in the early screening and prevention of COVID-19 but is also widely used in the detection of various infectious viruses such as influenza A, influenza B, and sexually transmitted diseases, highlighting its important position in the global medical field.
In the preparation process of PCR testing reagents, lyophilization technology stands out with its unique advantages. It can effectively ensure the biological activity of reagents, reduce the loss of volatile components during the lyophilization process, and provide higher stability and portability, freeing it from the constraints of cold chain transportation, laying a solid foundation for the widespread application of PCR testing reagents.
Guangzhou Ascend Precision Machinery Co., Ltd., as a pioneer in the industry, has been deeply involved in the research and development of lyophilized bead equipment since 2017. The independently developed and manufactured liquid nitrogen lyophilized bead dispensing system can accurately control the dispensing of a predetermined amount of reagent into liquid nitrogen through a high-precision metering pump, pre-freezing into small beads with very high consistency, laying a solid foundation for subsequent production. Among them, the FSH-DS528 fully automatic liquid nitrogen lyophilized bead dispensing system is equipped with an intelligent high-precision metering pump, fully-automatic liquid nitrogen addition device, temperature control device, nitrogen concentration detector, etc., which can achieve fully automatic unmanned reagent dispensing. It is equipped with 12-channel dispensing devices, capable of achieving a production capacity of up to 25,000 pieces per hour, becoming the preferred choice for the large-scale production of PCR testing reagents.

At present, Guangzhou Ascend's liquid nitrogen lyophilized bead dispensing systems have been sold to countries such as the United Kingdom, Japan, the United States, Canada, Australia, etc., and have successfully helped many medical equipment manufacturers to upgrade their production capacity. Among them, the Japanese genetic technology company K.K. MIRAI GENOMICS has used Guangzhou Ascend's liquid nitrogen lyophilized bead dispensing system to produce stable and storable PCR test kits, launched the GenPad test kit, and realized personal PCR automated virus detection through the automatic detection of the test kit and the query function of the mobile software, helping individuals to prevent the spread of diseases through PCR testing tools in a timely manner.
Guangzhou Ascend Precision Machinery Co., Ltd.'s liquid nitrogen lyophilized bead dispensing system has a dispensing accuracy of up to ±0.5%, providing quality assurance for the production of PCR test kits. Guangzhou Ascend will continue to research and manufacture higher requirements, more intelligent, and more precise liquid nitrogen lyophilized bead dispensing systems and lyophilized bead filling systems.
