SAMPLE VIALS, 20ML, 28 x 57MM, 33 EXPANSION BOROSILICATE GLASS

Packaged in a clear PETG tray complete with a slide or lift off dust cover. Vials are separated by a SBS partition to eliminate glass to glass contact. Caps are supplied compete in the package, not attached. Entire package is recyclable.

Vials are made from 33 expansion borosilicate glass which conforms to ASTM E-438 Type 1-Class A, USP Type 1 and ISO 3585. The high resistance to thermal shock along with its maximum chemical resistance makes this the glass of choice for vials along with most all laboratory glassware.

Polypropylene caps have a septa bonded to the cap, using the Chemglass SURE-LINK™ process. This inert process bonds the .125” PTFE Faced Silicone septa directly to the cap without adhesives, making the caps autoclavable and able to withstand multiple injections.

All vials are manufactured with the larger 24-400 thread, providing easier access for sampling or automation work.

Available with a choice of caps: green open top caps or white solid top caps with SURE-LINK™ PTFE faced septa. The white caps are ideal for storage purposes.
