Reusable Pyrex Test (Culture) Tubes
Reusable, heat resistant glass test tubes are thick walled to reduce breakage. Suitable for science & non-science applications alike. Note: Test tube diameter is nominal; there can be a variance of as much as +/- 0.5mm. We cannot guarantee they will fit any test tube racks we don't supply. No Labware 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. Please note that all online orders for test tubes require a minimum quantity order of 25. This does not apply to in-store orders.
