MACHEREY-NAGEL glass vials are made from 1st hydrolytic class glass. Snap ring vials N 11 are available in broad variety, incl. vials with/without label + scale, in clear or amber glass, plastic ones with different interior shape. Snap ring vials N 11 can be used either with snap ring closures N 11 or alternatively with crimp closures N11. 11.6 x 32 mm vials can be ordered as single components or - along with a closure of your choice - as a Vial Kit in a drawer-like PP-box for safe storage during consumption in the lab. For all vials you can ask for a certificate of conformity (CoC) for your own ISO documentation. Specialty vials, like those with integrated glass insert, are also included.
