EISCOBurette Clamp with Bosshead/Test Tube Holder - PVC Coated Round Jaws, Opens up to 45mm

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.

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

attractive if on display. we got a set for a displayed experiment and it looked good and functioned well, very adjustable.

This is a very good clamp for the price. it's great for setting up your stand items at any angle or distance from the other fittings to allow for a good strait setup.

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!

Good design.

This is a professional grade product, along with the stand and base. It looks and works great and has awesome functionality and articulation. I can easily place my devices where I want them. I am a very happy camper. Thank you.

I had to replace the hardware on this clamp. The adjusting screw and wingnut were unusable.
