Description
Distillation thermometer with red special filling covering the measuring range 0..+250 °C at a scale division of 1,0 °C. The instrument is fitted with a precision ground joint cone NS 14,5/23 and an immersion length of 120 mm, enabling secure insertion into standard laboratory distillation apparatus and reaction vessels. Its mercury-free red filling delivers clear scale readability while removing the handling and disposal concerns linked to traditional mercury thermometers. Designed for accurate temperature monitoring during higher-temperature distillation, boiling-point determination and solvent recovery, the thermometer integrates readily into organic-chemistry glassware trains. Produced by manufacturer Rettberg, the unit is supplied as a single piece with a net weight of 0,037 kg and is well suited to research, quality-control and teaching laboratories that require reliable, non-mercury thermometry. The robust construction and standard NS joint ensure repeated use across synthesis and purification workflows without compromising measurement clarity over the full operating span.

Questions about Thermometer, 0...+250°C:1°C, cone size 14,5/23, installed
What is this article?
Thermometer, 0...+250°C:1°C, cone size 14,5/23, installed is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
