Double Burette Clamp Fisher

Product Code : SCL-CL-12021

The Double Burette Clamp Fisher is a spring-loaded, scissor-action metal clamping device used for holding up to two burettes vertically on a standard laboratory retort stand. Designed for analytical chemists, clinical technicians, and science students, this instrument keeps graduation lines completely visible to ensure highly precise fluid tracking during titrations.

Product Description

The Double Burette Clamp Fisher from Science Lab Supplies provides excellent structural stability and operational ease for high-volume liquid handling workflows. Fabricated from premium-grade die-cast zinc-aluminum alloy, this buret holder securely mounts onto vertical support rods without slipping or sagging under load. The specialized scissor jaws act independently, allowing lab operators to attach or release individual glass tubes smoothly with a single-handed squeeze.

This heavy-duty clamp system is engineered to maximize visibility and reduce operational error rates. The contact tips are fitted with thick, non-slip rubber padding that grips the glass gently, absorbing physical shocks and preventing pressure fractures during intensive titrations. As a premium choice within our extensive laboratory hardware inventory, it provides institutional, industrial, and academic labs with a reliable, rust-resistant component built for daily chemical workflows.

Key Features

• Dual Tube Capacity: Anchors two independent glass burettes side-by-side to accelerate comparative chemical testing procedures.
• Unobstructed Scale View: Scissor-action grip profile avoids blocking crucial graduation marks or volumetric numbers on the glass body.
• Spring-Loaded Scissor Jaws: High-tension internal steel springs allow for instant, single-handed clamping and quick height modifications.
• Non-Slip Rubber Cushions: Fitted with resilient rubber jaw liners that absorb structural vibrations and safeguard fragile glass surfaces from scratching.
• Heavy-Duty Die-Cast Metal: Forged from structural zinc-aluminum alloy to prevent mechanical warping, bending, and cracking under heavy torque.
• Universal Rod Mounting: Central hook block safely connects to any standard laboratory retort support rod up to 16 mm in diameter.

Technical Specifications

What's Included in the Kit

• 2 x Double Burette Clamp Fisher Units
• 1 x Center Mounting Bolt and Thumb Screw Assembly
• 1 x Lab Apparatus Alignment and Safety Instruction Sheet

Applications / Uses

• Stabilizing two calibrated glass tubes simultaneously during competitive acid-base titrations and chemical neutralization assays.
• Serving as a high-durability, rigid structural mounting tool within academic chemistry science kits.
• Holding electronic pH electrodes or temperature probes securely beside fluid conduits in research labs.
• Anchoring specialized volumetric instruments plumb and level to minimize meniscus reading errors.
• Mounting narrow glass columns or chromatography tubes securely on a support frame for chemical extraction processes.

How to Use the Double Burette Clamp Fisher

1. Slide the central mounting sleeve of the Fisher clamp over the vertical column of an assembled retort stand at your preferred operational height.
2. Tighten the rear center thumbscrew firmly clockwise until the clamp housing is completely locked to the stand rod.
3. Compress the scissor-action handle on one side of the clamp to open the rubber-lined jaw fingers fully.
4. Place a clean glass burette vertically between the open pads, ensuring the tube sits perpendicular to the base platform.
5. Release your manual compression slowly, letting the spring tension lock the jaw pads securely around the glass body, then repeat for the opposite side if conducting a dual titration.

Handling Note: Always verify the central thumbscrew is anchored tightly to the support shaft before mounting heavy glass instruments filled with reagents. Never attempt to force a buret vertically while the scissor jaws are fully compressed closed on it.

Care & Maintenance

• Immediate Spill Response: Wipe down the alloy body and rubber pads immediately using a damp cloth if corrosive chemical titrants or concentrated acids splash the clamp.
• Spring Mechanism Integrity: Periodically inspect the internal steel springs for corrosion or loss of tension, keeping the joints clean and clear of dust buildup.
• Dry Equipment Storage: Store the clamp units flat in a low-humidity storage locker away from open chemical reagent shelves to protect the structural finish.

Frequently Asked Questions

What is a Double Burette Clamp Fisher used for?

It is a specialized laboratory hardware tool designed to hold up to two glass burettes simultaneously on a single retort stand. Its scissor-action grip keeps the tubes aligned vertically during complex quantitative titrations.

What materials are used to construct this clamp holder?

The main framework is manufactured from heavy-duty die-cast zinc-aluminum alloy with steel spring components, and the internal jaw pads are lined with high-friction vulcanized rubber.

Does this buret holder block the measurement numbers?

No, the unique scissor finger design of the Fisher style clamp grips the sides of the glass tube cleanly, ensuring that all graduation scale markings remain entirely visible to the user.

What sizes of burettes can it accommodate safely?

The self-adjusting spring jaws flex dynamically to accommodate a broad spectrum of standard laboratory glassware, comfortably fitting 10mL, 25mL, 50mL, and 100mL glass tubes.

Can this metal clamp withstand autoclaving?

While the metal components are highly heat-resistant, the integrated vulcanized rubber cushions can degrade under repeated extreme steam exposure. It is highly recommended to sanitize the clamp using standard liquid chemical wipes.
