Just recently the lab ran out of the cleanroom wipes and it takes too long to get from the supplier we usually buy. So I bought the cleanroom wipes from Best Buy which has Prime logo. Surprisingly I got excellent prices for single unit and lightning speed delivery of these cleanroom wipes. The 12X12 large wipes are highly absorbent with excellent wiping efficiency for any liquid or powder residues on the lab bench. Fantastic job and I will absolutely buy again.
