Perfect for aquarium testing
I bought these for testing aquarium water after having the ones from the kit break in my hands trying to get the cap off. I love that these are screw off caps. Only reason I took off a star is several so far we’re missing the seal gasket inside the lid.

None broken.
They all arrived intact. I used these for a craft project for the garden club. They are plant propagators. I bought them twice and used them for another craft— wildflower vases.

Best culture tubes I've ever used
I've been culturing bacteria for schools to study for many years and these are the best tubes I've ever used. The caps have the best seal I've seen at the best price. I can usually only find tubes at this price (around $.40 per tube) when buying by the thousand.I ran them through the autoclave at 15psi for 20 minutes with the caps half tightened and they all stayed on just fine and the caps didn't melt at all. The seals are just as flexible after autoclaving too. All of the caps will fit on any of the tubes as well. I've had problems with caps at this price only fitting on certain tubes in the set.I'll be buying these for as long as they sell them.Highly recommended!

Great value and quality test tubes
As I anticipated it did arrive with a few broken tubes in shipping on the outer edges of the box, I accounted for this when ordering. The glass is well made and sturdy (damaged tubes are due to light packing), uniform thickness, no signs of uneven internal stress on any tubes (viewed through polar filters). Even down some tubes it is a good value for glassware that will perform consistently tube to tube.

Good vials, bad packaging, shattered glass.
These test tubes are great, the right size for what I need, and reasonably sturdy in general. The problem is that they are not packed well. I have ordered them twice, and both times I have had broken tubes, small shattered glass spread throughout the box they come in. They come in layers of ten, with only thin foam padding in between each layer, not each individual vial, so when thrown around in shipping they tend to shatter.

Great product, poor packaging
The tubes are great, but don’t always arrive in one piece. The exchanges are handled quickly and effortlessly though
