The Burkle StopCock PA, electroconductive is a specialised liquid dispensing tap designed for solvent handling and applications where an electrically conductive dispensing system is required. The tap is manufactured from electrically conductive polyamide (PA) with PTFE media-contacting components.
Model 0525-1100 connects to containers with a G 3/4" external thread and is supplied with a conductive PA adapter for containers with a G 3/4" internal thread. Its angled discharge and rotatable spout help position the outlet for controlled dispensing, while the tapered 6 mm spout is designed for filling bottles with narrow openings.
Designed for:
Unlike conventional polyethylene or polypropylene dispensing taps, the StopCock PA is manufactured from electrically conductive polyamide. Burkle specifically identifies this construction for solvent applications where conventional PE or PP spigots are not suitable.
The media-contacting components are made from conductive PA and PTFE. This material combination provides a dispensing solution for compatible solvents while allowing the tap to be incorporated into an appropriately grounded electroconductive system.
Always check the manufacturer's chemical-resistance information before using the tap with a particular solvent or process liquid.
The StopCock PA fits containers with G 3/4" external threads. A supplied conductive PA adapter allows connection to G 3/4" internal threads, making the tap suitable for a wide range of compatible canisters and barrels with a bottom discharge connection.
The angled discharge can be freely positioned, while the rotatable spout is designed to help prevent dripping. The tapered outlet is suitable for filling bottles with narrow openings approximately 6–8 mm in diameter.

Important safety information
When handling flammable or highly flammable liquids, Burkle states that all parts must be grounded and recommends use of the appropriate anti-static kit. Follow applicable explosion-protection requirements and your facility's safety procedures.
The electroconductive construction of the StopCock PA is intended to help control electrostatic charge when it is incorporated into a properly grounded system. The tap should therefore be considered as one component of the complete liquid-handling and grounding system, rather than as a standalone safety device.
Burkle identifies the StopCock PA for use in Ex zones 0, 1 and 2 and explosion groups IIA and IIB. Application suitability depends on the complete system, the liquid being handled and applicable safety requirements.
The StopCock PA is designed for compatible containers with G 3/4" discharge connections.
The tap connects directly to G 3/4" external threads and includes a conductive PA adapter for G 3/4" internal threads. Burkle states that this allows the StopCock PA to be used with nearly all commercially available canisters and barrels where the discharge thread is located at the bottom.
| Application | Product Benefit |
|---|---|
| Laboratory solvent dispensing | Electrically conductive PA and PTFE construction is designed for compatible solvent applications. |
| Flammable liquid handling | Can be incorporated into a properly grounded electroconductive dispensing system. |
| Chemical storage containers | G 3/4" connection system is designed for compatible canisters and barrels. |
| Controlled liquid dispensing | Rotatable discharge spout helps direct the outlet during dispensing and filling. |
Burkle Anti-Static Set — 5602-1000
Burkle identifies the anti-static set as the required accessory for properly grounding the system. The set consists of three colour-coded connecting copper cables with clamps in a carrying case.
When dispensing flammable liquids, proper grounding of the container and equipment is essential. The anti-static set should be used in accordance with Burkle's instructions and the safety requirements of the application.
Although the StopCock PA is specifically designed for solvent applications, compatibility must be confirmed for the particular chemical being dispensed. Chemical resistance depends on the liquid, concentration, temperature and exposure conditions.
Burkle specifically directs users to its chemical-resistance information when selecting materials for a particular application. Do not assume compatibility with every solvent based solely on the product's general solvent designation.
Burkle 0525-1100 is the StopCock PA, electroconductive liquid dispensing tap. It is made from electrically conductive polyamide with PTFE as a further material.
The StopCock PA uses electrically conductive polyamide rather than conventional PE or PP. Burkle specifically describes it for solvent applications where commercially available PE or PP spigots cannot be used.
The inflow side uses a G 3/4" internal thread with a cap nut. The supplied conductive adapter provides a connection for G 3/4" internal-thread containers.
Yes. The StopCock PA is supplied with a conductive PA adapter for connection to G 3/4" internal threads.
Yes. Burkle specifically identifies the electrically conductive PA StopCock as suitable for solvents. The chemical resistance of the specific solvent should still be verified before use.
The manufacturer specifies a maximum operating pressure of 20 bar at +20 °C. Actual application suitability should be evaluated based on the complete system and operating conditions.
The outlet has an outer diameter of 6 mm and a nominal diameter of 5 mm. The tapered spout is designed for narrow bottle openings approximately 6–8 mm in diameter.
Yes. The discharge angle and spout can be positioned to help direct liquid during dispensing and reduce dripping.
When handling flammable or highly flammable liquids, Burkle states that all parts must be grounded and recommends use of the anti-static kit. Appropriate explosion-protection and site safety procedures must also be followed.
Burkle specifies the StopCock PA for Ex zones 0, 1 and 2 and explosion groups IIA and IIB. Suitability must be considered within the complete grounded system and the requirements of the specific application.
Cambridge Environmental Products supplies Burkle laboratory and fluid-handling equipment to Canadian laboratories, research facilities, industrial QA/QC operations and other professional users.
