Use lead cuffs and lead donuts, not lead rings. The "cuffs" and "donuts" were developed by I2R Company in suburban Philadelphia. They are now available from Glas-Col. These are "C" shaped and can be adjusted to fit various types of glassware, including
beakers. Being made of a plastic coated lead, they are heavy. They are a little pricey, but safety shouldn't be limited by price.

Subject: Re: [DCHAS-L] lab help for student with prosthetic hand
What about lead rings for water baths? Obviously, they would be more effective with Erlenmeyers and graduated cylinders than with beakers,
for instance, but they should be better than nothingÉat least in the interim.

Subject: [DCHAS-L] lab help for student with prosthetic hand
A student's prosthetic hand has been damaged (not lab related) and unfortunately they now have very limited ability to grasp/steady items such as graduated cylinders, flasks, etc. Does anyone know of some sort of countertop item that could
help stabilize graduated cylinders and other "tippy" items? I can imagine a few creative designs but I would rather have a commercial ADA-type product if possible. I've done a small bit of online searching but no luck so far; I'm probably not using the correct
search words.
