Welcome to the premier destination for Tomopal Stopcocks, where precision meets reliability in fluid control. This category features two essential packs of 3-way nylon stopcocks with Luer connections, available in quantities of 50 (P/N: 100-1130-X050) or 100 (P/N: 100-1130-X100), designed for seamless integration in laboratory experiments, industrial processes, and medical applications. Whether you're setting up a new workflow or restocking supplies, Tomopal delivers the quality and consistency professionals demand.

Why Tomopal Stands Out in Stopcocks

Tomopal has built a strong reputation for engineering high-performance fittings that prioritize durability and precision. Their nylon stopcocks are crafted from robust, chemical-resistant materials that withstand demanding environments, ensuring leak-free operation even under repeated use. Unlike generic alternatives, Tomopal's design emphasizes smooth rotation for effortless 3-way flow diversion, off, one port, or both, making them a go-to for users in Hydraulics, Pneumatics & Plumbing setups.

What sets Tomopal apart is their commitment to Luer compatibility, which guarantees secure, standardized connections across tubing systems. These stopcocks are lightweight yet tough, ideal for applications requiring frequent adjustments without compromising seal integrity. Shoppers appreciate the brand's focus on user-friendly features, like ergonomic handles for gloved hands and color-coded options for quick identification in busy labs.

Key Features to Consider When Buying

When selecting from this category, prioritize features that align with your workflow:

  • 3-Way Functionality: Easily control flow direction between three ports, perfect for multi-line systems.
  • Nylon Construction: Corrosion-resistant and autoclavable for sterilization in lab settings.
  • Luer Connections: Male and female Luer locks ensure airtight, universal fit with syringes, tubing, and manifolds.
  • Pack Quantities: Choose 50-pack for small-scale projects or 100-pack for bulk needs to optimize value.
  • Industrial-Grade Durability: Handles pressures and temperatures common in scientific and manufacturing environments.

These attributes make Tomopal stopcocks a reliable choice within our Luer Fittings and broader Stopcocks collections.

Comparing Tomopal Pack Options

Both packs offer identical 3-way nylon stopcocks (P/N base: 100-1130), differing only in quantity to suit varying project scales. The 50-pack (100-1130-X050) is perfect for individual researchers, pilot testing, or occasional use in educational labs, providing ample supply without excess inventory. For high-volume operations, like production lines or large-scale experiments, the 100-pack (100-1130-X100) delivers efficiency and convenience, reducing reorder frequency.

Buyers often choose based on usage frequency: smaller teams lean toward the 50-pack for flexibility, while institutional buyers prefer the 100-pack for cost-effective bulk handling. Both maintain Tomopal's exacting standards, so your decision hinges on volume rather than performance differences.

Common Use Cases for Tomopal Stopcocks

Tomopal stopcocks excel in diverse scenarios. In laboratories, they regulate fluid transfer during chromatography, perfusion systems, or sample preparation. Industrial users integrate them into pneumatic circuits, hydraulic test benches, and chemical dosing setups within Tube Fittings assemblies.

For medical and biotech fields, their Luer compatibility supports IV simulations, bioreactor feeds, and diagnostic equipment. Even in educational settings, these stopcocks facilitate hands-on demonstrations of fluid dynamics. If you're exploring alternatives, consider options like MEETOOT Stopcocks or StonyLabScientific Stopcocks for varied material choices, but Tomopal's nylon precision often leads the pack.
