Description
Melting point capillary tubes are slender glass capillaries open at one side, with an outer diameter of 1,9 mm and a length of 80 mm, prepared for classical melting-point determination. They are used to hold small solid samples during heating so that the melting range can be observed under controlled conditions on dedicated melting-point apparatus. The pack contains 100 pieces, supporting high-throughput teaching labs and routine quality-control workflows. A pack weight of 0,060 kg keeps storage and handling straightforward on the bench. These capillaries from manufacturer Stuart/Cole-Parmer suit laboratory appliances for melting-point measurement where one-sided open tubes of defined outer diameter and length are specified. Consistent geometry helps sample loading and alignment in standard capillary holders. Select this pack when reliable, single-open-end melting point capillaries are required for organic characterisation and identity checks.

What is this article?
Melting point capillary, Open at one side, OD 1.9, L 80 mm, 100 unit(s) is the article on this page. Luminix Health distributes Stuart/Cole-Parmer for laboratory use. It sits in Photometers & spectrophotometers, inside Spectroscopy & photometry, in Lab instruments.
A photometer reads absorbance at one or a few wavelengths. A spectrophotometer scans or selects many. Both send light through a cuvette or a well. The wavelength range, UV or visible, and the bandwidth decide what can be measured. A visible-only instrument cannot read a nucleic acid at 260 nm.
A photometer or spectrophotometer sends light through a sample and reads how much was absorbed. In the range where the Beer–Lambert relation holds, absorbance tracks concentration. A refractometer reads how a liquid bends light, which tracks dissolved solids. A polarimeter reads the rotation of polarised light, the classical measurement for sugars. The lamp, the wavelength and the cuvette path length are the three things that have to be right before the number means anything. The optical quantities trace to NIST and the BIPM.
