Eisco Labs Burette/Test Tube Clamp, PVC Coated Round Jaws, Opens up to 45mm in Dia.

There wasn't anything remarkable about this clamp - it is exactly as described. It is sturdy, adjustable with the little wing nuts and clamp, and stayed in place when clamped. If you just need a sturdy clamp to hold a little beaker or vial bottle, this is a great choice. I have to fill a week's worth of single-use needles for my husband with medication that takes a while to enter the needles, and using this clamp (clamped onto a dowel rod inserted into a base that I made) allows me to fill the needles a little easier. It's like a third hand!

The screws on it are very cheap in the plating on the metals kind of cheap but the clamps all aluminum and holds everything in firm does the trick for 10 bucks you can't complain. But I've noticed a lot cheaper items on other websites of far better quality through West labs Check them out that's where you going to get good quality stuff this extra shipping like Risco labs and prime you end up paying through the ice in the end that's all right if you like getting bent over the barrel

This is a solid clamp. I would trust this to hold my separatory funnel without needing an additional, superfluous ring clamp.

Decent product for the price. Works fine.

It does the job and is reasonably well made. I didn't have any problems with stripped threads or anything else. This may not be the cheapest offering of this product here but the vendor ships fast and is reportedly easy to work with unlike some of the other vendors that offer this same product at a cheaper price here on Amazon. Just make sure you READ the specs so you know what you're buying and what it's capabilities are before you click buy and you won't be disappointed. I use this particular unit for loosely holding 10ml fill syringes so that they drain into another container. works perfectly.
