Plate manufacturers often manufacture products based on the market demand. I think most research and diagnostic laboratories choose a 96 or 384 well plates since they are suitable to use most PCR machines, plate readers and multichanal pipets available in the market.

Dear Dr Tekewe,

Then why PCR machines have 96 or 384 wells why not 100 or 400 wells or any other value?

If PCR have 100 well structure (10 x 10) instead of 96 (8 x 12) then manufacturers will make PCR plates of 100 wells. But still my question is what is reason behind manufacturing of 96 well PCR or PCR plate.

Regards,
