Description
Diagonal condenser, plastic-coated, with stopcock socket NS 19/38 and spherical joint ball KS 35/20 is a laboratory cooler intended for rotary evaporators. It is manufactured from borosilicate glass 3.3 and carries a protective plastic coating over the glass body. The unit incorporates a stopcock socket NS 19/38 together with a spherical ground-joint ball KS 35/20, matching the connection geometry required by the target evaporator platform. This diagonal condenser from manufacturer Rettberg is specified for Heidolph rotary evaporators and belongs to the product group of laboratory coolers for rotary evaporation. The combination of borosilicate glass 3.3 and plastic coating provides the chemical resistance and mechanical protection expected in routine solvent-condensation work. Supplied as a single piece, the condenser is ready for direct installation on compatible Heidolph systems that accept the KS 35/20 spherical joint and NS 19/38 stopcock socket. Its diagonal layout follows the classic configuration used on many laboratory rotary evaporators, ensuring straightforward integration into existing glassware assemblies without alteration of joint standards.

Questions about Diagonal condenser, plastic-coated, stopcock socket size 19/38, spherical
What is this article?
Diagonal condenser, plastic-coated, stopcock socket size 19/38, spherical is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
