Review: Good Quality - 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. Review: Good value - 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. ## Features - DURABLE MATERIAL: Our 15ml falcon tubes are made of the high quality and high purity polypropylene material. These containers may be used as autoclave test tubes and have a max RCF of 12,000 x g - EASY MARKING: 15 ml Plastic centrifuge tubes also have designated white area for easy marking and identification. This little mark tube feature is very convenient for labelings purposes. - PRECISE GRADUATION: 15 ml centrifuge tubes also have graduation printed along side the test tube.
