Description
Inlet and aeration valve (Hei-VAP Bench-top) is a laboratory process accessory for precise redosing during an ongoing evaporation or concentration run and for controlled aeration of the system. Designed without a ground joint, the valve enables straightforward connection and operation free from a ground-glass interface, simplifying handling on compatible bench-top rotary evaporators. Operators can add reagents or solvents accurately while the process continues, and the built-in aeration function permits deliberate equilibration or venting of the apparatus atmosphere as experimental conditions require. The article is supplied as one piece and has a net weight of 0,120 kg. This inlet and aeration valve from manufacturer Heidolph is intended for Hei-VAP Bench-top configurations used in chemical synthesis, sample concentration and solvent recovery. By allowing mid-process dosing without full system interruption, it supports efficient workflow continuity in research, preparative and quality-control laboratories. Its compact form factor and dedicated system fit make it a practical spare or upgrade component within rotary evaporator accessory sets.

Questions about Ventilation- and replenishment valve (Hei-VAP Bench-top)
What is this article?
Ventilation- and replenishment valve (Hei-VAP Bench-top) is the article on this page. Luminix Health distributes Heidolph 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.
Which category should I open next?
