Quick answer: This Straight Socket Adapter with an integrated stopcock allows a laboratory glassware assembly to control fluid or gas flow directly at the joint, useful for isolating a system from the atmosphere or introducing a reagent in a controlled way. Socket Adapters, Straight Connection With Stop-cock is priced at approximately ₹370 (indicative market benchmark, incl. GST, August 2026).
This adapter combines a straight socket connection with a built-in stopcock, letting the user open or close the flow path at that point in a glassware assembly without needing a separate valve component. This is useful for isolating a reaction from the atmosphere when needed, controlling the rate at which a reagent or gas is introduced, or shutting off one branch of a multi-component setup while another remains active. Built for vacuum-tight performance, it’s suited to reflux, distillation, and synthesis setups in college and research chemistry laboratories where flow control at a specific point in the assembly matters.

Frequently Asked Questions
What does the integrated stopcock allow?
It lets you open or close the flow path directly at that point in the glassware assembly, useful for isolating a system from the atmosphere or controlling reagent/gas introduction.
What joint and bore size does this adapter use?
Exact joint and bore sizes have not been independently verified for this listing — confirm compatibility with STEMAids before ordering.
Is this suitable for a college organic chemistry lab?
Yes — socket adapters with integrated stopcocks are used in reflux, distillation, and synthesis setups common in organic chemistry coursework.
Does the stopcock need greasing?
Standard glass stopcocks typically need a light film of stopcock grease unless fitted with a PTFE plug — confirm the plug material with STEMAids.
Does STEMAids supply matching glassware for this adapter?
Contact STEMAids to confirm compatible flasks, condensers, and other components for a complete assembly.
Is STEMAids a registered manufacturer of this product?
Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
