ULAB Scientific Glass Test Tubes with Autoclavable Caps, Vol.16ml, 16x150mm, Medium Borosilicate Glass Material, Pack of 20, UTT1010

quite handy to have as I use mine for water testing purposes...

I bought these tubes to make ant starter nests and they are excellent. They don’t break easily and can be sterilised.

They feel very sturdy, came well packaged and are a perfect 20mm all the way from top to bottom and just needed a wash before use.

just what i needed for single stem roses

Turned up broken

I use these to store fuel additives in my car. They work great for that

Very well packed and protected. Only detail is that the lip of the test tube is very small (only protruding about 0.2mm) but works as intended

Items ate up to spec, packed securely. It's test tubes so hard to elaborate more 😀
