Watchglasses - Discontinued

Watch glasses can be used as beaker lids, to view aquatic invertebrates under a microscope or to dissolve crystals & powders. Or, fill a watchglass with water, freeze & repeat. Then put the 2 halves together & you have a lens!

No Glassware Returns

Glassware cannot be returned for any reason; this is for your safety and ours. It would be prohibitively expensive to test for bacteriological, chemical or radiological agents since there is no way to tell if glass has been contaminated just by looking at it. We would have to throw it away even if you claim to never have opened the package. Call first if you are unsure of what you need.
