Essential Wooden Test Tube Rack – Single Row, Double Row & Double Layer
Product Overview
The wooden test tube rack—also referred to as the test tube holder, wooden tube rack, laboratory test tube stand, or test tube drying rack—is a fundamental piece of laboratory equipment designed to securely hold and organize test tubes during experiments, storage, or drying. Crafted from seasoned hardwood with a smooth, polished finish, this rack offers a durable, chemical-resistant, and non-corrosive alternative to plastic or metal racks.
EduSupports offers a comprehensive range of wooden test tube racks in multiple configurations to suit different laboratory workflows:
Single-row standard racks – 6, 8, 10, 12, and 20 holes with uniform 22mm diameter
Double-row rack – 24 holes (12 × 2 rows) for higher capacity
Double-layer rack – 13 holes with mixed diameters (20mm upper / 26mm lower) for different tube sizes
Each rack is constructed from polished hardwood with a protective finish to minimize damage from chemical spills. The 22mm hole diameter accommodates standard test tubes up to 22mm in diameter.
Whether you need a compact 6-hole rack for a student workstation or a high-capacity 24-hole double-row rack for a busy teaching lab, EduSupports has the right solution for your laboratory.

Why Choose Our Wooden Test Tube Racks?
The wooden test tube rack offers several distinct advantages over plastic or metal alternatives.
First, its seasoned hardwood construction provides excellent strength, stability, and long service life in laboratory environments. Unlike plastic racks that may warp or become brittle over time, wooden racks maintain their structural integrity for years.
Second, the polished finish with protective coating resists chemical spills and is easy to clean. The smooth surface prevents damage to test tubes and minimizes contamination risks.
Third, the standard 22mm hole diameter accommodates most common test tube sizes, making these racks versatile for various laboratory applications.
Fourth, the double-layer 13-hole model offers unique versatility with two different hole sizes—20mm for smaller tubes on the upper shelf and 26mm for larger tubes on the lower shelf, plus six drying pins.
Fifth, the stable, heavy base design prevents tipping during use, ensuring safety for valuable samples and glassware.
