Description
Melting point capillaries, open on both sides are precision glass tubes intended for melting-point determination in analytical and organic chemistry laboratories. Each capillary measures 70 mm in length with an outer diameter of 1,2 mm and an inner diameter of 0,9 mm, manufactured from soda-lime glass and finished with clean right-angled cut edges for consistent sample loading. The open-ended design allows straightforward filling with powdered substances prior to insertion into melting-point apparatus. Supplied as 100 pieces in a convenient dispenser tube and 1 000 pieces per carton, the pack supports high-throughput laboratory use. These capillaries from manufacturer Marienfeld deliver uniform dimensions that promote reproducible results during thermal analysis. They are well suited for educational, research and quality-control settings where reliable melting-point data are required. The soda-lime glass construction provides the necessary clarity and thermal behaviour for standard melting-point methods while remaining economical for routine consumption.

Questions about Melting point determination tubes, both ends open
What is this article?
Melting point determination tubes, both ends open is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Markers & pens, inside Labels, signs & marking, in Lab safety equipment.
A laboratory marker is specified by the surface and the conditions it still reads after: frozen tubes, autoclaved labels, a solvent-splashed bottle. An ordinary whiteboard pen is not that marker. Permanent on paper and permanent on a cold polypropylene tube are different claims.
A label is how the next person knows what is in the bottle. A GHS label carries the pictogram, the signal word and the hazard statements the classification requires. A tape or a marker is only as useful as its survival in the freezer, the autoclave or the solvent it will meet. A safety sign is the instruction that stays on the door. The pictograms come from the CLP Regulation and are explained by ECHA CLP. Workplace signs sit with EU-OSHA.
