Review on 📦 Heathrow Scientific HS29022G Assorted Polypropylene Products by Kevin Carr

Bought these from Revain because they were cheaper than my university's lab supplies supplier. The product is durable and the holes for installing various pipes are well-formed. Falcon 50ml, 15ml tubes are well suited. As well as standard microcentrifuge tubes (0.5, 1.5, 2 ml). I've tried assembling individual racks into larger blocks and this is where the racks fail. Only two of the 5 packs could fit together. All others had slide locks that differed 1-2mm and therefore did not match other posts. This applies to both building directions (lengthwise and wide). However, assembling the racks into larger blocks is not a required feature for me and I will use individual blocks as such (which are fine for use in the bio lab). I wanted to mention the inappropriate stands in case anyone buys these stands for this feature.
