Product Description
When precision matters in your lab, the right tools make all the difference. The Polylab Stop Cocks (55301) are designed for researchers, students, and educators who need reliable fluid control without compromise. Whether you’re setting up a titration experiment, managing reagent flow, or conducting sensitive chemical reactions, these stop cocks deliver smooth operation and durability you can trust.
Crafted from high-quality borosilicate glass, these stop cocks resist thermal shock and chemical corrosion, making them ideal for both routine and demanding applications. The 2-way and 3-way configurations give you flexibility in directing liquid flow, so you can adapt to different experimental setups without hassle. The ergonomic design ensures easy handling, even with gloves, while the leak-proof seals prevent accidental spills that could ruin your work.
At eqipped, we understand that lab supplies aren’t just tools—they’re the backbone of your discoveries. That’s why we’ve sourced these Polylab stop cocks to meet the exacting standards of Indian labs, from university classrooms to advanced research facilities. Buy stop cocks online today and experience the difference quality makes in your workflow.
Why These Stop Cocks Belong in Your Lab
Not all stop cocks are created equal. Here’s what sets the Polylab 55301 apart:
The borosilicate glass construction isn’t just about durability—it’s about consistency. Unlike plastic alternatives that can degrade over time, these stop cocks maintain their integrity even with repeated exposure to acids, solvents, and high temperatures. This means fewer replacements and more reliable results in your experiments.
The 3-way option is a game-changer for complex setups. Need to divert flow between multiple vessels? No problem. This versatility reduces the need for additional tubing or connectors, streamlining your workflow and minimizing potential contamination points. For simpler applications, the 2-way version offers the same precision in a more compact design.
We’ve also paid attention to the small details. The PTFE plugs provide a tight, smooth seal that won’t seize up over time, while the clear glass body lets you monitor flow visually. This combination of functionality and transparency helps you catch issues before they become problems.

Common Applications in Indian Labs
From undergraduate chemistry labs to pharmaceutical R&D, these stop cocks are a staple in:
Academic Laboratories: Perfect for student experiments in titration, distillation, and chromatography. The durable design stands up to frequent use by multiple students.
Research Facilities: Used in synthesis reactions, solvent purification, and gas flow control. The chemical resistance ensures accurate results in sensitive procedures.
Quality Control Labs: Essential for sample preparation and reagent dispensing in industries like food testing, environmental analysis, and material science.
Medical and Clinical Labs: Employed in fluid handling for diagnostic tests and biochemical assays where precision is non-negotiable.
No matter your field, having reliable lab stop cocks for sale at your fingertips means one less variable to worry about in your experiments.
Choosing Between 2-Way and 3-Way Stop Cocks
Selecting the right configuration depends on your specific needs:
The 2-way stop cock is ideal when you need simple on/off control or to direct flow between two points. It’s perfect for basic filtration setups, burette connections, or when space is limited on your lab bench.
Opt for the 3-way stop cock when your experiment requires more complex flow patterns. This version lets you:
- Divide flow between two outlets
- Switch between different reagent sources
- Create bypass loops in your apparatus
Many researchers keep both types on hand to adapt to different experimental requirements. At eqipped, you can buy stop cocks online in either configuration, so you’re always prepared.
Maintenance Tips for Longevity
To keep your Polylab stop cocks performing like new:
Always lubricate the plug with a suitable grease before first use and after cleaning. This prevents seizing and ensures smooth operation.
Avoid over-tightening the stop cock, as this can crack the glass or damage the seal. A firm but gentle turn is all that’s needed.
Clean thoroughly after each use with appropriate solvents, then rinse with distilled water to prevent residue buildup.
Store with the plug in the open position to prevent the seals from sticking over time.
With proper care, these stop cocks will serve your lab reliably for years, making them a smart investment for any budget.
Safety Considerations
While these stop cocks are designed for safe laboratory use, always follow standard lab practices:
Wear appropriate PPE (gloves, goggles) when handling chemicals with the stop cock in place.
Inspect for cracks or damage before each use—compromised glass can fail under pressure.
Never use with high-pressure systems unless specifically rated for such applications.
Dispose of damaged stop cocks properly to prevent injury.

FAQs
Frequently Asked Questions
What’s the difference between 2-way and 3-way stop cocks?
The 2-way version controls flow between two ports (on/off or divert), while the 3-way allows flow between three ports, enabling more complex fluid direction. Choose based on your experimental setup needs.
Can these stop cocks handle corrosive chemicals?
Yes, the borosilicate glass construction resists most laboratory chemicals, including acids and bases. However, always check compatibility with specific solvents before use.
How do I know if my stop cock needs lubrication?
If the plug feels stiff or doesn’t turn smoothly, it’s time to apply a thin layer of lab-grade grease. Regular lubrication extends the life of your stop cock.
Are these stop cocks autoclavable?
While borosilicate glass can withstand autoclaving, we recommend checking the plug material’s temperature limits. The PTFE plugs in these models are generally autoclavable at standard lab conditions.
What’s the typical delivery time for stop cocks ordered from eqipped?
Most orders are dispatched within 1-2 business days. Delivery times vary by location, but you can expect your Polylab stop cocks within 3-7 days across major Indian cities.
