The Wincom Two Finger Clamp (commonly known as a Double-Prong Round Clamp) is a precision-engineered laboratory holding tool designed to secure straight cylindrical glassware, test tubes, burettes, and distillation necks. Featuring a classic two-jaw rounded profile lined with premium protective insulation, it delivers a uniform, encircling grip that distributes holding pressure evenly around delicate glass walls. This clamp is an essential hardware component specified for chemistry labs, academic science rooms, titration benches, and pharmaceutical research stations.

Technical Specifications

• Equipment Type: Two-Finger (Double Prong) Round Laboratory Clamp

• Material Composition: Heavy-duty die-cast zinc alloy body with a rigid chrome-plated steel extension rod

• Jaw Geometry: Symmetrical rounded two-finger design optimized for circular and cylindrical objects

• Jaw Coating/Lining: High-friction, heat-resistant cork lining or premium non-slip vinyl sleeves

• Clamping Opening Range: Adjustable jaw expansion accommodating diameters from 10mm up to 50mm

• Extension Rod Dimensions: Industry-standard mounting shaft (approximately 150mm length x 10mm diameter)

• Adjustment Screw: Single high-precision threaded metal screw with a wide ergonomic thumbscrew

• Compatibility: Connects seamlessly to any standard laboratory support frame using a standard bosshead holder

Key Features

• Optimized Rounded Grip Profile: The curved, concentric design of the two jaws mimics the natural shape of test tubes and flask necks, providing maximum surface contact and eliminating pinpoint structural stress.

• Anti-Fracture Protective Liners: Outfitted with premium cork insulation or heavy-gauge vinyl pads that cushion the glass against mechanical shocks and prevent micro-cracks or accidental structural breakage.

• Rapid Single-Screw Adjustment: Features a single, heavy-duty central threaded screw mechanism, allowing lab technicians to rapidly tighten, loosen, or release glassware with one hand during busy workflows.

• Industrial-Grade Thermal Defense: Built with high-purity alloys and heat-hardened coatings that resist direct flame proximity from Bunsen burners, aggressive solvent vapors, and accidental chemical splashes.

• Rigid Extension Shaft: The unyielding solid steel rod extends outward cleanly without bending or flexing, maintaining a completely level and horizontal orientation under heavy fluid loads.

Primary Applications

• Burette & Titration Setups: Gripping single or parallel burette tubes firmly at fixed vertical heights for precise volumetric drops and liquid readings.

• Test Tube and Boiling Experiments: Safely holding larger test tubes, culture containers, and sampling vials directly over open flames or inside heated water baths.

• Distillation & Reflux Matrix: Supporting vertical fractionating columns, extraction tubes, and round-bottom flask necks within complex glass manifolds.

• Probe and Sensor Mounting: Securing heavy thermometers, digital pH electrodes, and gas delivery tubes perfectly steady inside reaction beakers.
