SUCOHANS Two-Jaws Flask Clamp, PVC Coated Prongs LB-SPJ 1

works for what i need

The clamping end is made of light sheet metal and some arrived slightly bent. Once I worked on them, I was happy with their performance. They should work for most laboratory needs.

They worked for me, but I’m only doing essential oils. If somebody needed them for classroom work or industrial, I would tell them proceed with caution. Everything would probably work out just fine but that’s what went through my head when I started using them. For me , I will probably order a second time if need be.

These are extremely flimsy and suitable for occasional small scale lab work. If you wish to use them for holding anything beyond a 14/20 miniature scale apparatus, they will not work for you. They can hold maybe 3-4 lbs. If you have a condenser with tubes coming out of it, it simply can't support this kind of weight.
