Review on Laboratory Electronics for Pharmaceutical and Semiconductor Industries by Jason Rogness

I am very pleased to see a product at this price and bought it for the lab. If the descriptions are trustworthy I think I will continue to buy them. But I realized I had made a huge mistake: I used it to clean sample waffles (see picture) and then found that these towels were not of the quality I expected. It's a lot harder. Also, they are much lighter. The scale confirmed the huge difference: the weight of half a bag of Microcare is 918 grams / 150 pieces. In comparison, the other common brands I have weigh around 1150 grams / 150 pieces (luckily I was able to get them from another lab next door). Close observation of the placement of a Microcare wipe next to (left) another conventional wipe (right) shows that the woven structures of Mcirocare wipes are not as dense as the others. The range is not that high! Much more difficult (I think it's because the polyester percentage isn't as high as advertised, or at least the distribution of the polyester isn't as even) it's not safe to clean delicate surfaces like my sample panels, and besides, they absolutely are lint free. Due to the lower density, the absorbency does not meet the requirements for cleanroom wipes either. These poor quality towels completely ruined my rehearsals. They don't have to weigh 68 grams like other cleanroom wipes if they are durable. I doubt these wipes can be used in an ISO 5+ class environment unless further evidence is provided by a third party independent testing facility. Descriptions are misleading, be careful.
