Reagent Bottle Holder

These holders are for 100ml reagent bottles or any bottle with a diameter of approx 42mm. I was tired of the janky tip buckets we were using. Everyone in my lab likes them so much better than the previous option. I made several profiles, 2 of which are specific to the Roche Cobas calibrators for pH and Specific Gravity. They can be resized to your needs. I have included the 2, 3, and 6 bottle holders.
