Economical & sturdy. Excellent replacement for the more flimsy API aquaria test tubes. Easy to handle, no lip defects & take regular handling without breakage. Stored & used reliably with the test rack.
Good to know they worked for you. Small, defect free tubes are hard to make & takes proactive monitoring to achieve.
I am well pleased with the test tubes I ordered. Test tubes were economical, packaged well and were shipped quickly. I would order from this company again.
Glad we could help.
As others have stated, delivery was very prompt and as expected. I would order from them again. Prices seem very reasonable. Unfortunately, not being familiar with mm sizing, the test tubes were a bit narrow for the wire flower holder I needed a replacement for, but I am still able to use it.
We should have listed American as well as metric units. The problem is that there is always some tube variance. So, if the specs state +/- 0.5mm, sometimes a batch has many that tend to +0.5mm while another may tend to -0.5mm.?
Some hardware or plumbing stores carry small o-rings/rubber washers that you can slip under the rim to fix this. Or, see if you can get very small rubber bands.
