Description
Distillate guide according to Dr. Howorka NS 14/23 is a specialised laboratory glassware component for controlled routing of distillate in distillation assemblies. It features a PTFE valve stopcock with 6 mm opening, a socket NS 14/23, a cone NS 14/23 and a lateral cone NS 14/23, enabling secure ground-joint connections within standard distillation trains. The design supports precise take-off of fractions during simple or fractional distillation under atmospheric or reduced pressure. Supplied as 1 pc with a net weight of 0,063 kg, the unit integrates directly into existing apparatus without adapters. From manufacturer Witeg, this Dr. Howorka-style guide is suited to organic synthesis, solvent recovery and preparative chemistry workflows where clean distillate transfer improves process control. The PTFE stopcock offers chemical resistance and reliable shut-off for common laboratory solvents and reagents. Ideal for research, teaching and quality-control laboratories requiring interchangeable NS 14/23 glassware for efficient vapour and liquid handling.

Questions about DISTILLING LINK, ACC. TO DR. HOWORKA,
What is this article?
DISTILLING LINK, ACC. TO DR. HOWORKA, is the article on this page. Luminix Health distributes Witeg 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.
