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.

A centrifuga hè una fonte di aerosols. Una larga gamma di attività - cumprese u riempimentu di tubi di centrifuga, a rimozione di tappi o coperchi da i tubi dopu a centrifugazione, è a rimozione di u liquidu supernatante è poi a risospensione di pellets - pò purtà à a liberazione di aerosol in l'ambiente di u laboratoriu.
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.
Se un tubu rottu o fuga, ùn apre micca a centrifuga per almenu 30 minuti dopu a corsa. Siccomu questu ùn pò micca sempre esse rilevatu prima di apre i buckets o u rotore (un sbilanciamentu bruscu pò esse un primu signu di rottura di tubu), ricumandemu d'aspittà almenu 10 minuti in ogni mumentu prima di apre i cuntenituri.
Inoltre, duvete carricà è scaricate i buckets o rotor in un cabinet di biosegurità (in particulare in virologia è micobacteriologia) per minimizzà u risicu di scappà aerosols.
