Introducing our in-house tooled NW Glass Flanges series. These flanges are available in sizes ranging from 10mm ID to 160mm and come with mating knuckle clamps and teflon centered oring. These are essentially the glass equivalent to stainless steel KF flanges, and can be used to interface with the metal KF series.  We stock 25, 40 and 50 mm ID flanges, clamps and seals.

NW Glass Flanges
 

These flat flanges have proven to be useful in the fabrication of electrochemical cells and microbial fuel cells; basically any cells requiring sealing a membrane between sides. They are useful for mounting windows as well.

Shown below and on the right is the largest version of this flange, an NW160. It has an ID of 150mm, just under 6", for easy access to the interior.

Shown below is a large 2-part cyclone assembly utilizing NW flanges, both for access to the interior of the cyclone itself, through the NW160 flanges, as well as for porting through the NW50 flanges.
