Advantages

Material USP1, borosilicate glass Mainly used for headspace analysis for gas chromatography. No risk of incorrect sealing as with crimp bottles. Easier to close and open, especially since the magnetic gland is difficult to compress Reduced core withdrawal and needle protection due to thinner septa Can be used for headspace and SPME due to thinner diaphragm. The special pre-cut diaphragm (the silicone layer is cut into slits, but the PTFE layer remains intact) allows safe penetration of the sensitive SPME phase with virtually no coring.
