EISCO Double Burette Clamp Support With Rod
The EISCO Double Burette Clamp Support with Rod provides a sturdy mounting option for burettes up to 100 mL. It features alloy jaws designed to hold glassware securely without marring delicate surfaces. The 12 mm diameter stainless steel support rod runs 24 inches long, enabling flexible stand configurations. This clamp is suitable for labs that require a reliable, fixed support with room for height adjustments during titration or sampling tasks.
EISCO Double Sided Butterfly Style Burette/Tube Clamp
This double clamp provides a secure grip on burettes or tubes with spring-loaded jaws that adapt to various diameters. Made from high-strength alloy and powder-coated for longevity, it offers consistent clamping force and durability in demanding lab environments. The dual-jaw design is ideal for experiments requiring two vessels or tubes at once, keeping lines neat and secure during complex procedures.
EISCO 5PK Burette Clamp with Bosshead
This set includes five clamps featuring PVC-coated round jaws that provide a firm grip without marring glassware. Openings range from 15 mm to 45 mm, controlled by a screw-adjustable jaws mechanism. The adjustable angle and length allow clamping over a 360-degree range, with overall lengths typically between 13 cm and 15 cm. Ideal for kits that need multiple clamps to support several burettes or tubes simultaneously.
EISCO Burette/Tube Clamp, Single
This single clamp uses spring-loaded, high-strength alloy jaws to hold burettes or tubes securely. It supports objects up to 7/8 inch in width or diameter and features a powder-coated finish to extend service life in busy chemistry labs. The combination of robust grip and corrosion-resistant coating makes it a reliable choice for routine titration setups and educational demonstrations alike.
EISCO Burette Clamp with Bosshead
Equipped with a PVC-coated round jaw and a built-in boss head, this clamp offers easy attachment to lab stands and supports. The adjustable angle and length provide a flexible range of motion, enabling precise alignment for burettes up to 45 mm in diameter. Its sturdy construction supports repeated use in classroom labs and research settings where dependable clamping is important.
StonyLab Aluminum Double Burette Clamp
Manufactured from die-cast aluminum with rubber grips to minimize slippage, this double clamp uses loaded springs to secure burettes firmly. The powder-coated finish resists scratches and helps ensure long-term use in busy lab environments. Its lightweight yet sturdy design makes it suitable for portable setups or bench-top experiments where consistent stability matters.
StonyLab Plastic Double Burette Clamp
This ABS-made clamp provides a durable, lightweight option with rubber-grip jaws to prevent slippage. The spring-loaded design ensures a secure hold on burettes and tubes while minimizing the risk of damage to graduation marks. It is a practical choice for teaching labs and hobbyist setups that require dependable but economical equipment.
Buying Guide
- Jaw material and coating: PVC-coated jaws protect delicate glassware from scratches, while alloy and aluminum jaws offer strong gripping force for heavier setups.
- Clamp opening and compatibility: Check the maximum diameter the clamp can secure and ensure it matches your burette size and rod diameter requirements (commonly 7/8″ to 1″ or up to 45 mm openings).
- Spring-loaded vs manual: Spring-loaded clamps provide consistent pressure with less adjustment, ideal for frequent changes, while manual clamps allow fine-tuning of angle and grip.
- Angle and rotation: A 360-degree adjustable clamp increases flexibility for aligning burettes in crowded or multiple-stand systems, especially in complex titration experiments.
- Durability and finish: Powder coating and corrosion-resistant materials extend life in wet or chemical-heavy environments; consider finishes that resist scratches and lab wear.
- Quantity considerations: For classroom kits or research labs, consider sets (like the 5-pack) for efficiency and consistency across multiple burettes and tubes.
- Brand and compatibility: EISCO products dominate this category with a wide range of clamps; ensure your stand hardware (boss heads, rods, and stands) matches the chosen clamp’s mounting options.
- Price-to-performance: While some clamps offer premium materials and adjustability, assess whether the additional features are necessary for your workflow or simply add convenience.
- Safety and handling: Ensure clamps have secure locking mechanisms and avoid harsh materials that could chip or crack glassware during heavy handling.
- Maintenance: Wipe down after use to remove chemical residues; check spring tension periodically and replace worn parts to maintain clamping stability.
