Questions about Inner centering ring/PTFE DN 25, with FEP-coated Silicone O-Ring
What is this article?
Inner centering ring/PTFE DN 25, with FEP-coated Silicone O-Ring is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Other instruments & spare parts, in Präzisionsinstrumente.
Some instruments do not sit cleanly in one measuring principle, and every instrument eventually needs a spare: a lamp, a fuse, a seal, a knob. The spare has to be the part for that model. A near match is a different part. Calibration of the instrument, once it measures, belongs with EURAMET, BELAC and the BIPM.
