JN Sciencetech brand PTFE Test Tubes are manufactured from pure virgin PTFE for maximum consistency and homogeneity which results in a “super-smooth” internal surface finish. The PTFE test tubes are inert and usable up to 280°C.
Simply put, contaminants can leach out of glass and may then be detected in one’s samples even in many of today’s modern instruments of analysis. Leaching has occurred from time immemorial, of course, but it is only in the recent past that these trace impurities began to be detected. However, if PTFE test tubes are used, one can completely avoid this potential problem. Three versions of the product are available: a.) Screw cap b.) With Rim Round Bottom C.) Without Rim. No screw caps in round or conical shape bottomed test tubes.
