Description
Rotilabo® capillary tubes are slender glass capillaries open on one side for laboratory work such as melting-point determination and related physical-property tests. Each tube has an outer diameter of 1,35 mm and a length of 80 mm, dimensions chosen for straightforward sample loading and use in standard melting-point apparatus and sample holders. The pack contains 100 pc(s) under the Rotilabo® line from manufacturer ROTH SELECTION, giving a practical stock quantity for teaching labs, quality control and routine organic characterisation. Open-ended construction on one side supports capillary action when taking up powdered or molten samples. Pack weight is 0,035 kg. These tubes are grouped with devices for melting-point determination and fit everyday workflows where uniform outer diameter and length matter for reproducible packing of the sample column. The 1,35 mm outer diameter and 80 mm length allow clear observation of the melt transition in typical heating blocks or oil-bath setups. Laboratories can keep the 100-piece unit at the bench for repeated determinations without frequent replenishment, maintaining consistent capillary geometry across successive measurements.

Questions about Rotilabo®-capillary tubes, open on one side, outer-Ø 1.35mm, L 80mm, 100 unit(s)
What is this article?
Rotilabo®-capillary tubes, open on one side, outer-Ø 1.35mm, L 80mm, 100 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Temperature measurement accessories, inside Temperature measurement, in Lab instruments.
These are the connectors, the wells and the spare probes that complete a thermometer or a logger. A thermocouple connector of the wrong type silently adds an error. The accessory has to be the same sensor family as the meter.
A thermometer reports a temperature. A liquid-in-glass thermometer is a calibrated column. A digital thermometer is a sensor and a display, and the sensor, not the display, is what is calibrated. An infrared thermometer reads a surface and depends on emissivity. A data logger stores the reading over time. Without a stated uncertainty and a calibration point, the number is only an indication. The scale is maintained by the BIPM and compared by EURAMET. Accreditation is BELAC.
