EISCO 48PK Test Tubes, 15ml - Borosilicate 3.3 Glass - 1.2mm Thick Walls, Beaded Rim - Superior Heat & Chemical Durability - 5.25" Tall, 0.6" Diameter

After accidentally detonating a test tube I realized I was running low, and that I should look into getting more. I got these and so far none have detonated. Very useful.

The price is the best.quality i had no complaints about either.

One arrived broken but the rest were in good condition. The diameter seems to be spot on but the length isn’t quite 5.25”. They will work great for what I need them for so all in all I’m happy with them and would purchase again.

Durable and properly shipped, these items were delivered to me without a single chip or defective in any of the test tubes.

Turned out smaller than I needed. A couple were broken in the box.

Really low quality glass and poor packaging. The tubes were literally stacked on each other without any insulation between them. The worst part is that they sent broken tubes in a smashed box. Sizes also seemed to be inconsistent. Made in India garbage.

Good price fast shipping

As soon as I picked up package I could hear glass pieces shaking around. They seem smaller than described. Ordered replacement, hope they arrive in better condition
