stonylab 5pk Test Tube Clamps, Laboratory Chrome Plated Iron Test Tube Holders Stoddard Clamps with Finger Grips, 6.5 inch Length

Description

Product Overview

StonyLab presents a professional-grade set of test tube clamps designed for the demanding environment of modern laboratories. Each clamp in this five‑piece package is constructed from high‑quality iron that has been meticulously chrome‑plated to provide a smooth, corrosion‑resistant surface. The chrome finish not only enhances durability but also offers an easy‑to‑clean exterior that resists the buildup of chemicals and residues commonly encountered in scientific work.

The clamps measure 6.5 inches (16.5 cm) in overall length, a dimension that balances reach and control. This length allows users to comfortably manipulate test tubes that range up to 50 mm in diameter, making the clamps suitable for a wide variety of glassware, from small analytical tubes to larger reaction vessels. The ergonomic finger grips are strategically positioned to give the user a secure hold without excessive force, reducing hand fatigue during extended procedures.

One of the standout features of the StonyLab clamps is the self‑closing mechanism. When released, the spring‑loaded arms automatically return to a closed position, ensuring that the test tube remains securely clamped even if the user momentarily loses grip. This safety feature minimizes the risk of accidental spills or breakage, which is especially important when handling volatile or hazardous substances.

Beyond functionality, the clamps are engineered for longevity. The anti‑rust treatment combined with the robust iron core means the clamps can withstand frequent cleaning cycles, exposure to solvents, and the rigors of daily laboratory use without compromising performance. StonyLab backs each set with a one‑year limited warranty, underscoring confidence in the product’s quality and providing peace of mind for purchasers.

Overall, the StonyLab 5‑pack test tube clamps deliver a blend of precision engineering, user‑centric design, and reliable durability, making them an essential addition to any lab’s toolkit.

Usage

These clamps are ideally suited for a broad spectrum of laboratory activities. In chemistry labs, they are frequently employed to secure test tubes during titration, heating, or filtration processes, where stable positioning is critical for accurate results. The finger grips allow technicians to quickly adjust the clamp’s position, facilitating rapid changes between experimental steps.

Biology researchers benefit from the clamps when handling delicate samples that require gentle yet firm support. The self‑closing feature ensures that once a tube is clamped, it remains in place even when the operator needs to free both hands for pipetting or microscope work. This hands‑free capability improves workflow efficiency and reduces the likelihood of sample contamination.

Educational settings, such as high school and university labs, also find these clamps valuable. Their intuitive design makes them easy for students to learn proper handling techniques, while the sturdy construction can endure the frequent misuse typical of teaching environments. Instructors appreciate the safety aspect, as the clamps help prevent accidental breakage of glassware during student experiments.

Beyond traditional laboratory benches, the clamps can be integrated into portable field kits for environmental testing, where reliable equipment is essential under variable conditions. Their compact packaging and lightweight nature (approximately 90 grams per clamp) make them convenient to transport without sacrificing performance.

Regardless of the specific application, the clamps support a range of glassware beyond test tubes, including small beakers, vials, and reaction tubes, provided the diameter does not exceed the 50 mm limit. This versatility ensures that a single set can serve multiple purposes across different experimental protocols.

FAQ

Can the clamps be used with glassware other than test tubes?

Yes, the clamps are compatible with any cylindrical glassware that does not exceed a 50 mm diameter, such as small beakers, vials, and reaction tubes. The adjustable jaws and self‑closing feature allow for secure handling of a variety of laboratory containers.

How do I clean the clamps after exposure to chemicals?

Cleaning is straightforward: rinse the clamps with warm water and a mild detergent, then dry them with a lint‑free cloth. The chrome plating resists most solvents, but for aggressive acids or bases, a quick dip in a neutralizing solution followed by thorough rinsing is recommended.

What is the warranty coverage for these clamps?

StonyLab offers a one‑year limited warranty that covers any manufacturing defects. If a clamp arrives damaged or develops a fault within the warranty period, contact our support team for a replacement or repair. The warranty does not cover damage caused by misuse or improper handling.

Are the clamps suitable for high‑temperature applications?

The iron core can tolerate moderate heat, but prolonged exposure to temperatures above 200 °C may affect the chrome coating. For high‑temperature processes, it is advisable to use heat‑resistant clamps specifically designed for such conditions.

How many clamps are included in the package and what are their dimensions?

The package contains five individual clamps, each measuring 6.5 inches (16.5 cm) in length. The overall dimensions of the set are 29.53 × 3.94 × 5.91 inches, and each clamp weighs approximately 90 grams, making the set lightweight yet robust.
