9 Dram (1.13 oz.) Clear Polystyrene Plastic Vial - 100 pack

I teach online homeschool classes and I needed a way for students to do an inexpensive, small-scale titration lab. I used 1 mL syringes as the titrators and drilled a hole through the flexible plastic lid of these vials and the tips of the syringes fit perfectly. Students can now gain the experience of a titration without having to use large, fragile, and expensive burettes! These vials are extremely economical and good quality. Also, I can't say enough about Thornton Plastics' customer service. I found these online and emailed to ask a few questions to help me see if these would work for my purpose. They immediately sent me a free sample of several different sizes and emailed some ideas on how to make the hole in the lid. Then, FedEx delivered the vials to an odd location. When I contacted Thornton Plastics they looked up where the shipment was actually dropped off and I was able to locate them. Very responsive and helpful customer service!

They fit perfectly on small insect aspirators. Caps fit great, easy on and off.

Good quality clear vials that come with tight lids. Very Pleased.
