Hello everyone!

I'm looking for actual dimensions of septum which is usually referred as "Shimadzu Plug" size (generally used in GC). It looks like a thick cylindrical insert with flat cap and tiny guide hole on the flat side of cap (like here: https://www.shimadzu.com/an/gc/column_consumable/feature6.html ).

Does anybody use that type of septa and can measure following parameters for me:

- insert OD

- insert height

- cap OD

- cap thickness

P.S. I'm not trying to copy those septa. I need to do multiple gas sampling over the time and I'm looking for septa with proper geometry and long durability.

Thank you!
