Description
Melting point tubes with an internal diameter of 1,55 mm, an outer diameter of 2,35 mm and a length of 90 mm are clear-glass capillaries closed at one end for melting-point determination. These precision capillaries are intended for sample preparation and visual thermal analysis in research, teaching and quality-control environments. The sealed end keeps powdered or crystalline samples in place during heating, and the transparent glass allows clear observation of melting behaviour in conventional melting-point instruments. Uniform capillary dimensions support consistent packing and comparable heat-transfer conditions across successive measurements. Supplied as a pack of 1000 pieces from manufacturer Hirschmann, the 90 mm length offers comfortable handling when loading samples and placing tubes into heating blocks. They integrate readily into everyday capillary workflows used in organic chemistry and pharmaceutical testing. As a standard laboratory consumable, they provide a reliable option for routine melting-range determination without specialised fittings.
This article is part of Pipetting accessories, in Pipettes & pipette tips.

Questions about MELT.POINT TUBES, ID 1,55 MM, ONE END CLOSED OD 2,35 L 90 MM
What is this article?
MELT.POINT TUBES, ID 1,55 MM, ONE END CLOSED OD 2,35 L 90 MM is the article on this page. Luminix Health distributes Hirschmann for laboratory use. It sits in Pipetting accessories, inside Pipettes & pipette tips, in Lab consumables.
Pipetting accessories are the boxes, the ejectors, the spare seals and the carousel parts around a pipette and its tips. A seal set is model-specific. A tip box that does not match the rack footprint will not sit on the pipette aid.
A pipette moves a measured volume. A volumetric pipette delivers one line. A graduated pipette delivers along a scale. A Pasteur pipette is an uncalibrated transfer. A piston pipette uses a tip, and the tip has to seal on that pipette. A filter tip adds a barrier so aerosol from the sample does not reach the piston. Serological pipettes are the long graduated tubes used with a controller. The volume and the fit are the specification. Piston pipettes are treated under ISO laboratory apparatus. In-vitro work also meets ISO in vitro diagnostic systems.
