Double funnel Mark tubes
Double funnel Mark tubes
These special Mark tubes made of borosilicate glass 3.3 are particularly suited to flow measurements.
The measuring range in the center of the capillaries has a wall thickness of only approx. 20 µm. The sides, however, are made from thicker-walled material, making it easier to assemble the tubes in a liquid circulation system.
Thin tubes have proven to be effective for adapting these capillaries. The tubes are secured in the funnels on both sides using liquid Teflon (PTFE).
