The types of HPLC vials cap septa,Why should replace the septa. If you are interested, please contact us!
The septum needs to be replaced regularly to prevent: air leakage, decomposition, sample loss, column flow or split flow rate drop, ghost peak, and column efficiency. Different septa have different properties:
Loss and temperature optimized septum (BOT): 5183-4757
Wide temperature range, low loss → suitable for mass spectrometry, inlet temperature up to 400 degrees, reducing stickiness at the inlet
Long life septum 5183-4761
Pre-perforation, prolong service life, reduce nucleation; automatic injection is preferred for septum, suitable for overnight operation; injection up to 400 times and 350 degrees high temperature.
Advanced green septum 5183-4759
Long life, high temperature resistance; many injections; reduce the paste of the inlet; temperature up to 350 degrees HPLC vials
The above three kinds of septa are advanced septa, plasma-treated, non-stick mat universal diaphragm: temperature 350 degrees, the number of times is 200, economical.
This is the end of the introduction of The types of HPLC vials cap septa,Why should replace the septa.I hope it can help you.
