From: Water bath is more efficient than hot air oven at thermal inactivation of coronavirus
Efficiency of pathogen inactivation by water bath and air oven. TGEV in 1 mL was precooled to 8 ℃ and placed into 56 ℃ water bath or air oven respectively, removed at the indicated time intervals, and quenched on ice. Virus titers were assessed and expressed as TCID50. The dot line in blue and red showed the best-fit pattern of water and air oven inactivation by linear regression analysis respectively. The gray line represents the lower limit of detection at 10e1TCID50 /mL. Data are representative of 3 independent experiments and presented as mean ± SD. The low limit of detection for viral cytopathic effect was 10e1 TCID50 /mL
