Description
Replacement stopcock assembly for Nalgene™ acrylic buret is a dedicated spare part for restoring accurate liquid delivery on break-resistant acrylic burets. It is intended for use with 25 mL acrylic Nalgene break-resistant burets and restores the stopcock function required for controlled titration and volumetric work. The assembly type is a stopcock unit, matching the original buret configuration that employs a PMP tip with TFE stopcock and plug.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.
These burets are specified to meet ASTM E287 standards, supporting reliable laboratory volumetric applications when the stopcock is in good condition. Replacing a worn or damaged stopcock helps maintain leak-tight operation and reproducible drop control without exchanging the entire buret body. The part is supplied from manufacturer Thermo Scientific - Laboratory Plastics under the Nalgene™ laboratory plastics line. Pack size is 2 pc(s), suitable for instrument maintenance stocks and teaching or routine analytical labs that keep acrylic burets in service. Select this assembly when servicing compatible 25 mL Nalgene acrylic burets.

Questions about Replacement Stopcock Assembly for Nalgene™ Acrylic Buret
What is this article?
Replacement Stopcock Assembly for Nalgene™ Acrylic Buret is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics 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.
