0.2ml Microcentrifuge Tubes with Snap Cap 1000 Pcs, Disposable Micro Centrifuge Tubes Mini Microcentrifuge Tube Test Vials Plastic Sample Storage Container for Lab

Works good

Not 1000 in the bag. Probably weight counted and 40 under. Not a big deal but I needed to buy another to get the 995 that I need with the first order coming in short.

These are great! But i couldn't help, but giggle a little bit at just how many I got! Which is fine! Will last a very long time! I have a couple uses for these tiny containers..... I'll be using them to hold/display very small gemstones and beads that are considered unique or more fancy. I also plan to use them to hold samples of different scents that I use to make candles, soaps, etc! Containers are very nice and close perfect, with a little "snap" you hear upon pushing shut! They do wash up easy if need be, but use a little cotton swab to dry the inside!

Good

This review will be short and sweet: these little 200 microliter microcentrifuge tubes work just the same as those from any more familiar brand name, but they cost a fraction as much. I've been a life sciences researcher for nearly 40 years, and mainstream scientific suppliers outrageously overprice expendables like these. I've used Annhua tubes in a variety of non-critical applications, especially in instructional settings, with no issues whatsoever.
