Bekith200pc Plastic Centrifuge Tubes, 15ml, Conical Bottom, Graduated Marks, Blue Screw Cap, No-Leak

The like very much the product..!! cheap and good quality.!!

I bought these for a health clinic to collect dog urine for a research study. They worked great and were an excellent price

Very reliable product. Quality is nice, and good for regular lab use.

Good product. Several tubes very clearly broken or cleanly cracked. Good buy though

What can I say? They work. No problems and the best price.

I love these containers for geocaching keeps my logs dry even through winter highly recommend

The product description states "All tubes are sterile and certified free from DNase, RNase, DNA, PCR inhibitors & endotoxins", however there is clearly visible debris in the bag where the tubes were packaged in, the bag (which looks used and not new) was torn in multiple spots, and the tubes look like they have been used, as the numbers are faded on some of them, and they look very scuffed up.

How do these get so many good ratings. The caps leak. The markings are no where close accurate.

Los he comprado para almacenamiento de muestras sólidas, me hubiera gustado que tuvieran el fondo plano pero los tubos son correctos. Sí que parece que el rotulado no es muy duradero, pero no me preocupa porque yo etiqueto los tubos, por lo que marcas de graduación o espacio para texto no son importantes para mi. Tengo la duda de si los tapones son estables (que no se suelten), la rosca parece pequeña, pero por el momento aguantan. En general muy bien, pero editaré si me encuentro algún problema.

Provette ben costruite e in plastica di buona qualità. Buona la tenuta del tappo. Prezzo molto conveniente

Tubes are fine, only the white labeling part comes loose after pressure cycle
