These get the job done. I did have a few explode on me in a 10000g centrifuge, but it may be my fault for leaving a non polar solvent in them for too long. Unless proven otherwise, 5* for good value.

These little plastic test tubes are perfect for pre-measuring coffee. I use them to portion out the right amount for each serving; I then freeze those servings, so you can enjoy premium coffee throughout the year without it going off. Super easy to clean and reuse.

I bought these for long-term storage of mycelium cultures on agar suspended in water. I filled them 1/2 full with water, and they withstood the pressure cooker @15 PSI for 20 minutes just fine. I’d buy them again if I ever need more. I would have preferred orange caps over blue so that sharpie writing would be more visible, but it’s not a flaw of the product.

Use them to hold charge for my 50 cal muzzleloader. Works great
