Kashi Scientific 15mL Screw Cap Conical Centrifuge Tubes, Sterile Test Tubes with Blue Lids, Lab-Grade Polypropylene Plastic, Printed Graduation and Write-on Spot [15mL, 50]

I like to bring my own Gatorade G2 on half-marathons so I put a little in these; each 15mL tube is good for about 8oz. of water.

Very good product.

I bought these slants for mycology, and they work perfectly.

These are good quality and they come in a sealed bag which keeps them sterile. I purchased them to be used as slants for mycology work but they were too small to work with.

Perfect for using with students in elementary school

Marvelous for storing collected seeds! You can write on the tube or use a label. There they all are, safe and sound till next season.

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.

wrong size shiped, but works well.

Muy buen producto los tapones resisten temperatura
