Glass Test Tubes

  • Borosilicate (pyrex) glass: heat resistant/autoclavable
  • 18mm tubes have reinforced rims for stoppers
  • 18x150mm tube is a standard lab test tube
  • 18x150mm= 3/4x6"
  • Fits 2 different test tube racks
Note (1): 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 or stoppers we don't supply.
Note (2): The 55907RP is identical to the 55907R but has "18x150mm" in white ink printed on it. They are fine for science but may not be suitable for decorative use.

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.
