These 25x200mm (1x8") glass test tubes, have a nominal outside diameter of 25mm. If you have a hole that is slightly wider than the OD of the tube, an o-ring or elastic band, etc. placed under the rim may fix the problem. You can also see how the o-rings were used to position the test tube in this wall mounted spice rack. Rubber o-rings are generally available in hardware or plumbing supply stores.

Save even more with tube & stopper combos. No one beats our quality & price even with "free" shipping.

Exactly what I was looking for, and cheaper than my regular ( not anymore) supplier! Shopping on their website is very easy and fast delivery! Claude

Thanks for the feedback. We don't pad our prices so we can offer "free" shipping-it's the delivered cost to your door that counts!

Great products and even better customer service. This company is awesome. When you call, there is always someone picking up the phone and that person can solve your issue. No need to be transferred here and there. It's so refreshing and time efficient when you too have a business to run. Thank you and great job everyone at Indigo Instruments.
