Dear Tshewang,
We have had two labs for IPV five dosis per vial, one of them is Bilthoven with a box of 4,01 liters with 280 vials, i.e 1.400 dosis. En each refrigerator you can storage 348,6 dosis per liter. The only thing is the box doesn´t fit inside the basquets of the refrigerator.
The second one is Sinovac with a box of 40 vials with a volume of 0,882 litres. This is 226,7 dosis per liter. This secundary box is more practical to fit inside the basquets of the refrigerator.
I suggest you calculate the capacity per basquet 5, 7 or 9 basquets depends of the refrigerator, or vaccine carrier.
Greetings.
