40pcs of Glass Serological Test Tubes with Black Bakelite Screw Caps Silicon Liners, Vol.30ml 20x150mm with Marking Area, Borosilicate Glass Material, Flat Bottom, LVH005

I just received a case of 16ml tubes from Labvida. I was actually surprised that all were perfect and intact. This case was packed nicely with cardboard inserts to separate all the tubes.

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.

Pretty reasonable and does what it says it does. Only thing is my daughter dropped one and it broke. Maybe I'm scoring this harshly on that basis, but growing up I seemed to recall at school they would bounce rather than break.

THESE TEST TUBES CAME WELL PACKAGED WITH ZERO BROKEN. THE PERFECT SIZE AND THEY WERE IF A VERY HIGH QUALITY. AND THE PRICE WAS EXCELLENT. I WOULD BUY AGAIN and I WOULD RECOMMEND THESE TO ANYONE.

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.

Just as described.

I broke a few caps by tightening them loosely on the vials. Kind of annoying because the vials themselves are great and I can't buy the caps separately. Otherwise these are good vials.

I used these for a classroom lab. They were very durable and easy to clean. I only wish that waterproof labels came with them.
