Description
Pouring spout, cone NS 34,5/35, with Keck clip is a laboratory adapter intended for flasks and bottles. Fabricated from borosilicate glass 3.3, it carries a standard ground joint cone of NS 34,5/35 that delivers a secure, leak-resistant fit for controlled pouring and liquid transfer in chemical, analytical and preparative settings. The supplied Keck clip firmly locks the joint, minimising the chance of accidental separation during handling or tilting. With a net weight of 0,055 kg the component balances solidity and manageable weight for routine bench work. Its borosilicate construction supplies the chemical resistance and thermal stability expected of quality laboratory glassware. Available as a single piece, this adapter from manufacturer Rettberg integrates easily into existing ground-joint assemblies and is suitable for reagent dispensing, sample transfer and general glassware workflows requiring reliable pouring performance.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Pouring spout, cone size 34,5/35, with Keck clamp
What is this article?
Pouring spout, cone size 34,5/35, with Keck clamp is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Ground-joint glassware (other), inside Distillation & extraction glassware, in Labware.
This is ground-joint glassware that is not a head, a condenser or a Soxhlet: receivers, blank joints, odd adapters. A ground joint is named by the wide end and the length, such as 29/32. Mismatched joints do not seal, even with grease.
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.
