Internal Screw Caps

from $26.00

Designed with a threaded neck on the inside of the tube with a silicone O-Ring. The internal threads ensure a secure and tight seal that prevents any leaks or contamination of the samples inside the tube. Additionally, the use of virgin-grade polypropylene ensures that the tubes are free from any contaminants or impurities that may interfere with the integrity of the sample.

These tubes are designed for short or long-term storage at cryogenic temperatures, making them an ideal choice for scientists working with biological samples, cell lines, and other sensitive materials.

  • Made with FDA medical grade polypropylene. All production, assembly, and packaging links are completed using automated equipment in a 100,000 clean room-level purification workshop, minimizing manual operations and interventions.

    *ISO 14001

    *ISO13485:2016

    *ISO 9001:2015

  • Made using a patented in-mold labeling process, the graphic contrast and clarity of the prefabricated digitally printed labels can easily reach more than 1200dpi, which is more than 4 times the best level of laser etching technology. The labels are placed flat on the product surface, and the protective layer is matte-treated to ensure reliable label reading.
