A day before the lockdown began, we were frantically procuring molecular sieves, Oxygen flowmeter. Oxygen flow meter was out of stock everywhere, the simple reason is it has the word oxygen in it. We found one source, and only after coming back to the lab we realized that it is a nitrogen flow meter. We have to recalibrate it. Canisters were machined and brought, with all the flanges and connectors. The valves still did not come. Went to SP road, but it was already locked down at least half-a-day before the rest of the state.
