Stopcock Aspirator Bottle and Carboy

Description

The Stopcock Aspirator Bottle and Carboy, also known as a laboratory dispensing spigot or polypropylene bottle tap, is designed to control the flow of liquids from compatible laboratory storage containers. Manufactured by PolyLab, this replacement stopcock features a polypropylene body designed for routine laboratory use. It provides a convenient dispensing arrangement for aspirator bottles and carboys used to store distilled water and other compatible laboratory solutions. The stopcock incorporates a threaded connection that screws into the dispensing outlet of a compatible container. Its sealing arrangement is designed to help prevent leakage during storage and dispensing when correctly installed.

Its half-turn opening and closing mechanism allows users to control liquid flow through a simple manual adjustment. This feature is particularly useful in laboratories where liquids are dispensed regularly from larger storage bottles or carboys. The stopcock is autoclavable, allowing it to be sterilised using suitable laboratory steam sterilisation procedures. The manufacturer specifies 121°C autoclaving for this component. Follow the manufacturer’s instructions, including opening the stopcock and disengaging threads as required to prevent pressure build-up. The replacement spigot is suitable for compatible PolyLab aspirator bottles and carboys, making it useful when an existing stopcock becomes worn, damaged or requires replacement. It allows users to maintain the dispensing function of an existing container without purchasing a complete replacement bottle.

This polypropylene stopcock is commonly used for laboratory water dispensing, reagent handling and compatible liquid transfer applications. Its manually operated design makes it suitable for routine activities in teaching laboratories, research institutions and industrial testing facilities. Before installation, confirm that the threaded connection and sealing components are compatible with the intended container. Although polypropylene offers chemical resistance to many laboratory solutions, users should verify the chemical compatibility of all wetted components before dispensing specific chemicals.

Safety Precautions: Ensure the stopcock is securely fitted before filling the container. Check for leakage before use, avoid overtightening the threaded connection, and follow approved procedures when handling hazardous liquids or autoclaving the component. The product is supplied as one PolyLab replacement stopcock only. The aspirator bottle, carboy and other laboratory dispensing accessories are not included unless specified separately.
