Product description

In a distillation or reflux train, the DWK Life Sciences DURAN® Liebig Condenser, 2 Screw-On Plastic Hose Connections, NS 24/29, 400 mm Jacket Length returns vapour to the flask (or collects distillate) by way of a straight inner tube inside a water jacket, giving steady in-line condensation for distillation. The extended jacket provides more cooling surface for higher distillation and reflux rates. DURAN® borosilicate glass 3.3 construction tolerates the thermal stress of repeated heating and cooling.

Key Features:

  • Brand: DWK Life Sciences
  • Range: DURAN®
  • Product Type: Liebig condenser
  • Jacket Length: 400 mm
  • Ground Joint: NS 24/29
  • Hose Connections: 2 screw-on plastic hose connections
  • Material: DURAN® borosilicate glass 3.3
  • Application: Distillation and reflux cooling

For labs that distil or reflux regularly, it offers steady heat exchange and simple tubing changeovers. Make sure your hoses fit the connectors and the NS 24/29 matches your flask.

Burette vs Pipette: Key Differences and Which to Use

This guide explains the practical difference between a burette and a pipette, two instruments that are often confused because both dispense measured volumes of liquid, but that are built for genuinely different jobs. It breaks down how a burette's stopcock and full-length graduated scale let an operator dispense a variable, watched volume and stop the instant a reaction reaches its endpoint, versus how a pipette (volumetric, graduated or micropipette) is built to transfer one known or pre-set volume in a single action. Rather than presenting the two as competing options, the piece frames them as complementary tools tied to different steps in a procedure: burettes for titration and any reaction where the target volume isn't known in advance, pipettes for sample preparation, dilutions and any step where the volume is already fixed.

Top 5 Brands for Graduated Cylinders in 2026

This guide compares the five graduated cylinder brands most commonly used across Australian laboratories: Hirschmann Laborgeräte (DURAN® glass), Kartell (PMP plastic), ISOLAB Laborgeräte, BRAND (BLAUBRAND®) and VITLAB. Rather than treating graduated cylinders as interchangeable, it breaks down what actually separates them, Class A versus Class B accuracy tolerances, glass versus plastic construction, base stability and certification standards such as USP conformity, and explains which of these differences genuinely matter depending on the work.

This guide compares the five Erlenmeyer flask brands most commonly used across Australian laboratories today: DWK Life Sciences (DURAN®), ISOLAB Laborgeräte, LLG Labware, BRAND and Kartell. Rather than treating all Erlenmeyer flasks as interchangeable, it breaks down what actually separates them in practice, wall thickness consistency, thermal shock resistance, neck and closure compatibility, and material choice between borosilicate glass and polypropylene, and explains which of these differences matter for which kind of lab work.
