DualSeal

Features of DualSeal

• Do not dispose of the inlaid PTFE sheet! Keep it as it is during use! This PTFE sheet acts as a second layer air seal.
  
• Do not place anything on the septum cap! This will significantly reduce seal quality.
  
• Repeated use can lead to increasing the number of holes or increasing the size of existing holes and will over time lead to an increase in air leakage. To prevent deterioration of the septum, reduce the number of injections as much as possible, or purchase a smaller bottle size.
• In the case of halogenated solvent solutions such as dichloromethane, we recommend a minimum number of injections because the punctured area of septum butyl rubber will be invaded by the vapor of the halogenated solvent, etc. Also, after removing the syringe needle, please be careful of contamination, as the solution on the needle tip may dissolve the butyl rubber.
• Please note that if you remove the needle without withdrawing the reagent from inside the needle, the liquid may adhere to the septum and cause it to deteriorate.

【Example of how to transfer the entire content】

1. Secure reagent bottles before opening.
2. Open only the top lid (blue).
3. ttach a needle to the PTFE tube for liquid delivery connected to the reaction vessel filled with inert gas. Insert the needle into the septum so that the tip of the needle reaches the bottom of the reagent bottle.
4. The liquid is delivered by inserting a syringe filled with inert gas, or a needle connected to an inert gas pump, into the septum and sending inert gas into the gap in the reagent bottle.
5. First remove the needle from the liquid delivery tube, then remove the needle that was delivering the inert gas.

• Do not remove the outer cap when you remove the septum cap.
• Take extra care to avoid any spillage of inner liquid.
• Once the cap has been opened, its airtightness cannot be guaranteed even if it is tightened again using a tool. The same applies when using a DualSeal cap opener.
