Spring Test Tube Holders Walfront Steel Clip Clamp 14.5cm 5-Piece Set

Description

Product Overview

The Walfront Spring Test Tube Holders are engineered to meet the rigorous demands of modern laboratory work. Each holder is forged from high‑grade alloy steel, providing a robust construction that resists bending, cracking, and corrosion even after repeated exposure to chemicals and moisture. With a length of 14.5 cm, the clamps are perfectly sized to accommodate standard test tubes ranging from 15 mm to 25 mm in diameter, ensuring a snug yet gentle grip that prevents slippage or breakage during vigorous shaking or heating. The spring‑loaded mechanism delivers consistent pressure, allowing users to insert and remove tubes quickly without sacrificing stability. Packaged as a five‑piece set, the product offers excellent value for educational institutions, research facilities, and independent laboratories that require multiple clamps for simultaneous experiments. The sleek silver finish not only conveys a professional appearance but also simplifies cleaning—simply wipe with a damp cloth or rinse under running water to remove residues. Detailed specifications include a weight of 3.52 ounces per clamp, overall dimensions of 3.94 x 3.94 x 3.94 inches, and a UPC of 794419690104, ensuring traceability and ease of inventory management.

Usage

These test tube holders excel in a variety of laboratory settings. In academic chemistry labs, instructors can rely on the secure grip to demonstrate titration, reflux, and precipitation reactions without worrying about tube displacement. In industrial research environments, the clamps support precise analytical procedures such as spectrophotometry, chromatography, and sample preparation, where maintaining tube orientation is critical for accurate results. The ergonomic design also benefits field technicians who need portable, reliable equipment for on‑site sample collection and analysis. Because the clamps are made of non‑magnetic steel, they are compatible with magnetic stirrers and other equipment that may generate magnetic fields. The spring‑loaded action reduces hand fatigue during prolonged experiments, making them suitable for high‑throughput workflows where dozens of tubes are handled consecutively. Additionally, the clamps are compatible with standard test tube racks, allowing seamless integration into existing lab setups without the need for additional accessories.

FAQ

Can these clamps hold test tubes of different diameters?

Yes, the spring‑loaded mechanism adapts to a variety of standard tube diameters, typically ranging from 15 mm to 25 mm, providing a secure hold without damaging the glass.

Are the clamps compatible with magnetic stirrers?

Absolutely. The alloy steel used is non‑magnetic, so the clamps can be placed on magnetic stirrers without interfering with the magnetic field or causing attraction.

How do I maintain the clamps to prevent rust?

After each use, simply wipe the clamps with a damp cloth or rinse them under running water, then dry thoroughly. The stainless‑steel alloy resists rust, but regular cleaning ensures optimal performance.

What is the warranty coverage for these test tube holders?

Walfront provides a one‑year limited warranty covering any manufacturing defects. If a clamp fails due to material or workmanship issues within this period, we will replace it at no cost.

Can I purchase additional clamps to expand my set?

Yes, additional single clamps or larger multi‑piece kits are available through our catalog. Contact our sales team for bulk pricing and inventory options.
