“Shelter in Place” order has been playing an important role to slow down the COVID-19 spreads, but COVID-19 testing is still in great demand to identify the infected asymptomatic patients and prevent close contact infection. Regardless of what techniques are used for the testing, safe and correct sample collection is essential. With more and more COVID-testing kits are approved for FDA EUA, getting high-performance sample collection kits due to lack of supply becomes harder and harder.

We provide limited supply of high-quality sample collection kits that meet COVID-19 testing needs:

  • Inactivation of COVID-19 virus (SARS-CoV-2) to reduce health risks for lab technicians during downstream operations
  • Ambient transportation and storage up to one week save shipping cost and provide convenience
  • Virus sample stability in VTM ensures downstream sample processing and testing accuracy by reducing false-negatives
