Highly Airtight Storage Bottle

This product is a highly airtight storage bottle of our original design. It is suitable for storage of various standard solutions and/or samples, such as volatile solvents, agrichemicals, and dioxins. The airtight seal is acquired by adopting a perfluoro O-ring between the bottle mouth and the cap with a special shape. It prevents shrinkage of the material due to temperature change and does not swell due to the effect of vaporized organic solvents. In addition, by adopting the external thread type cap, the content materials are never attached to the cap. Long-term shelf-life of various solvents is possible in a wide temperature range (room temperature to freezing conditions (-20 °C)). This product is deal for storing various standards and samples.


  • Original design
  • Shrinkage of container and cap due to temperature change does not affect the airtight seal
  • External screw type cap with no contact between sample and cap
  • Top sampling hole allows for collection directly with a micro syringe
  • Maintain an airtight seal of 99% or more for storing organic solvents for 3 months at room temperature to frozen (-20 ° C) storage
  • Available 4 sizes, 1 mL, 2 mL, 5 mL, 10 mL

Airtight test

10 mL of acetone, 10 mL of hexane, 10 mL of diethyl ether were placed in our highly airtight storage bottle (10 mL) and a similar bottle from Company A (10 mL), then sealed tightly. They were left at room temperature and stored frozen (-20°C.). The weight of each was measured from 1 week to 3 months later.

  • Realize higher airtightness than other companies' products (Company A)
  • 99% or more sealability for 3 months storage
