Description
RINGCAPS 44,7 µl NA-hep are micro disposable capillary pipettes manufactured from DURAN® glass for precise small-volume handling. Each pipette carries a ring mark and is supplied with a declaration of conformity according to DIN 12600, aligned with ISO 7550 and CE marking under IVD 98/79 EG. The sodium-heparinised (NA-hep) finish supports blood and related clinical or analytical sampling workflows where defined microlitre aliquots are required. The nominal volume of 44,7 µl enables reproducible capillary uptake for routine laboratory use. Offered under the ringcaps® brand from manufacturer Hirschmann, the units are intended as single-use pipettes and are packed for convenient bench supply; note the stated minimum order quantity of four boxes. Typical applications include haematology, clinical chemistry and other micro-volume procedures that demand calibrated glass capillaries with clear volume indication. Storage and transport conditions are specified in the product data for controlled laboratory environments.

Questions about RINGCAPS 44,7 µl, NA-HEP, CC, BOX = 250 PIECES
What is this article?
RINGCAPS 44,7 µl, NA-HEP, CC, BOX = 250 PIECES is the article on this page. Luminix Health distributes Hirschmann for laboratory use. It sits in Sample containers & jars, inside Bottles & containers, in Labware.
A sample container or jar is the vessel the sample travels in, with a closure that survives the trip. The volume and the liner decide whether the sample that arrives is the sample that was taken.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
