Centrifuges for Nucleic Acid Testing of Coronavirus COVID-19

Time : 2022-01-24 Hits : 46

As the outbreak pneumonia that caused by coronavirus COVID-19 has spread across continents, more and more people begin to worry that the epidemic would upgrade into a pandemic. Scientists and doctors are working together internationally to study further about this new coronavirus and trying to develop the vaccine as soon as possible.

For laboratory diagnosis, centrifuge is one of the essential equipments in laboratory nucleic acid testing of coronavirus COVID-19. As a manufacturer and enterprise of lab centrifuge, we have the responsibility to give our efforts to fight against this disease. Currently we have 3 models suitable for the clinical and diagnostic laboratory.

The above 3 models and rotors are more needed than often due to the increasingly huge needs from laboratory diagnosis on coronavirus COVID-19. Xiangzhi company is trying the best to ensure the production and supply for these models. And on the order hand we consider the biosafety as prior thing for lab workers, we highly appreciate the advices and suggestions of improving our centrifuge designs that’s able to protect lab workers better.

Lastly, please be aware of the following points when handling with hazard hazardous Material in laboratory:
Working in clinical diagnostic laboratories usually means working with potentially infectious samples like blood or other bodily fluids. But handling infectious microorganisms or harmful chemicals is quite common in research laboratories as well. To ensure the safety of laboratory personnel and to prevent laboratory acquired infections (LAIs) or other health hazards, reasonable precautions must be taken throughout the whole workflow.

Centrifuge is one source of aerosols. A broad range of activities – including filling centrifuge tubes, removing caps or lids from tubes after centrifugation, and removing supernatant liquid and then resuspending pellets – can lead to the release of aerosols into the laboratory environment.
Thus, aerosol-tight lid or biocontainment cover is essential for centrifuging hazardous samples, such as blood collection tubes (vacutainers)

Aerosol-tight lids do not prevent formation of aerosols during centrifugation; rather, they ensure aerosols cannot leak from the closed system.
If a tube break or leak, do not open the centrifuge for at least 30 minutes after the run. Since this cannot always be detected before you open the buckets or rotor (a sudden imbalance can be a first sign of tube breakage), we recommend waiting at least 10 minutes at all times before you open the containers.
Also, you should load and unload the buckets or rotor in a biosafety cabinet (especially in virology and mycobacteriology) to minimalize the risk of escaping aerosols.
