NITROGEN OR SCHLENK TUBES

Nitrogen or Schlenk Tubes

Nitrogen tubes, also known as Schlenk tubes, are essential components in laboratories specializing in organic, organometallic, or coordination chemistry, where handling air- or moisture-sensitive compounds is required. Their design allows safe and controlled work under inert or vacuum atmospheres.

At Pobel, we offer high-quality Schlenk tubes made of borosilicate glass, with ground joints and high-performance valves—ideal for procedures requiring anhydrous and oxygen-free conditions.

What Are Schlenk Tubes and What Is Their Purpose?

Schlenk tubes are designed to hold substances in the absence of air and moisture by using an atmosphere of nitrogen, argon, or vacuum. They are widely used in sensitive syntheses where exposure to oxygen can alter or destroy the compound.

These tubes typically feature:

• A side valve (Schlenk tap or stopcock) for connection to vacuum/inert gas lines

• A standard ground glass joint for sealing with a stopper or connecting to other apparatus

• A heat-resistant glass body for reactions or thermal processes

Common Applications of Schlenk Tubes

• Oxygen- and moisture-sensitive reactions

• Handling of pyrophoric or air-unstable reagents

• Assembly with Schlenk lines or inert gas manifolds

• Transfer of liquids or solids in controlled atmospheres

• Crystallizations or storage under nitrogen

They are indispensable in academic research labs, advanced chemical synthesis, catalysis, materials development, and more.

Technical Features of Pobel’s Schlenk Tubes

• High-purity borosilicate glass, resistant to thermal and chemical stress

Frequently Asked Questions

Why is it called a Schlenk line?
The Schlenk line (also known as a vacuum gas manifold) is a common chemical apparatus developed by Wilhelm Schlenk.

What is a Schlenk flask used for?
This flask is used for air-sensitive substances. It is part of the Schlenk system, which is designed for working with compounds prone to oxidation.
