What diameter are the tubes, and will they stand up in a test tube holder with 16mm holes?

The replacements are the same size as the originals so will go within the holder

Is there a stand to buy for these vials. I can’t see one on Amazon as the holes are too big for the vials.

Don't really know to be honest. Sorry

If i put 1 in the quantity how tubes wi,l i recueve ?

You will get a pack of 24 tubes with caps

fantastic

after trying to take the cap off a test tube and taking most of the tube with it a got this replacement pack and it’s absolutely fab. the caps aren’t as tight (but still a perfect seal) so i’m not as worried about them breaking the test tubes as i try to get them open.

Great find

Am extremely accident-prone, so am forever dropping and mashing these test tubes. The 24-pack is a great find, will hopefully last for a while.

They are what they are, but they arrived on ...

They are what they are, but they arrived on time (as they said), neatly packed with all intact.Going to make testing 5 tanks a whole lot easier from now for sure, with plenty to spare.Being glass should last longer than plastic tubes (which get scratched) & certainly easier to clean than plastic tubes (which in the past have also stained).
