Essential Wooden & Bamboo Test Tube Clamps – 5 Styles for Safe Lab Heating
Product Overview
The wooden and bamboo test tube clamps—also referred to as test tube holders, test tube clips, spring plate clamps, or peg-style test tube clamps—are essential hand tools for every chemistry laboratory. Designed to securely grip test tubes during heating, transfer, or mixing operations, these clamps provide a safe, heat-insulating barrier between the user’s hand and hot glassware.
EduSupports offers a comprehensive selection of test tube clamps in five distinct styles to suit different laboratory needs:
Wooden Round Hole (15-30mm): Solid wood, 200×22×11mm, spring mechanism
Wooden Diamond Hole (~30mm): Solid wood, 198mm length, flexible grip
Bamboo Round Hole (12-25mm): Eco-friendly bamboo, 180×16×12mm, lightweight

Why Choose Our Test Tube Clamps?
The wooden and bamboo test tube clamps offer several distinct advantages for laboratory test tube handling.
First, their natural wood or bamboo construction provides excellent heat insulation. Unlike metal tongs that conduct heat, these clamps keep your hands safe when heating test tubes over Bunsen burners or alcohol lamps.
Second, the spring mechanism ensures a firm, secure grip on test tubes without slipping. The spring tension is calibrated for easy one-handed operation while maintaining a strong hold.
Third, the multiple styles and sizes allow you to choose the right clamp for your specific tube diameters. Round holes provide a snug fit, while diamond holes offer more flexibility for different tube sizes.
Fourth, the durable construction ensures long service life. Made from stable, high-quality materials, these clamps resist warping and maintain their grip over years of use.
Fifth, the cost-effective design makes these clamps ideal for educational institutions, where budget-friendly yet reliable tools are essential for student labs.

How to Use – Best Practices
Setup Instructions
Select the right clamp – Choose based on your test tube diameter
Open the clamp – Squeeze the handles to open the jaws
Position the tube – Place the test tube into the hole or between the jaws
Release – Allow the spring mechanism to grip the tube securely
For heating – Hold the clamp at a comfortable distance from the flame
Heating Tips
Hold the test tube at a slight angle when heating
Keep the tube moving in the flame for even heating
Never point the test tube opening toward yourself or others
Use the clamp as a handle – the wood/bamboo will stay cool
Maintenance & Care
Wipe clean with a soft, dry cloth after each use
Clean with mild soap and water if exposed to chemical spills
Avoid prolonged exposure to strong solvents
Periodically check spring tension
Store in a dry location when not in use
Safety Precautions
Always use a clamp when heating test tubes – never hold directly
Ensure the tube is securely gripped before heating
Use appropriate personal protective equipment (safety goggles, lab coat)
Inspect the clamp regularly for cracks or damage
Do not overheat the clamp itself
