Glass Tubes with Caps

Sealed Design Keeps Samples Clean with Glass Tubes with Caps

 

We have 12 years of professional experience in lab glassware production, and product are designed for high-standard sample storage needs. The integrated cap design saves you the trouble of purchasing additional sealing stoppers, and it effectively isolates air and dust to prevent sample volatilization and pollution. These tubes are perfect for biological sample storage, reagent subpackaging and microbial culture, and they are the ideal choice for labs with high cleanliness requirements for long-term sample preservation.

We select non-toxic and tasteless borosilicate 3.3 glass as the raw material for these tubes. The material has super stable chemical properties and can withstand temperature changes from -20℃ to 150℃, suitable for both high-temperature sterilization and low-temperature refrigeration. We adopt integrated firing technology to ensure the cap and tube body match precisely without loosening or liquid leakage. The tube mouth is finely polished and smooth without burrs, and we conduct strict full inspection in all production links with a size error of ≤0.2mm for each tube.

The capacity scale on the tube body has a reading error of ≤0.5%, which allows you to measure reagents accurately for various experiments. The round bottom design enables the tubes to be placed directly on test tube racks for easy storage and operation. You can clean the tubes repeatedly and conduct 121℃ high-pressure sterilization, and they have strong corrosion resistance to strong acid, strong alkali and organic solvents. We provide a three-year warranty, support customized specifications for bulk orders, and ensure timely delivery and stable quality to meet your large-scale lab use needs.
