Essential Wooden Nessler Tube Rack – Single Layer & Double Layer – for Colorimetric Tubes
Product Overview
The wooden Nessler tube rack—also referred to as the Nessler tube stand, colorimetric tube rack, Nessler cylinder rack, or tube support for Nessler color tubes—is a specialized piece of laboratory equipment designed to securely hold Nessler tubes (also known as color comparison tubes or Nessler cylinders) during colorimetric analysis, water quality testing, and various analytical procedures.
Crafted from high-quality natural wood with a polished clear varnish finish, these racks offer a durable, chemical-resistant, and aesthetically pleasing alternative to plastic or metal racks. Unlike domestic versions that may have strong paint odors and visible wood knots, our export-grade wooden racks feature carefully selected timber with minimal imperfections and a clean, low-odor finish.
EduSupports offers a comprehensive range of wooden Nessler tube racks in both single-layer and double-layer configurations, designed to accommodate 10ml, 25ml, 50ml, and 100ml Nessler tubes with precisely matched hole diameters.
Whether you need a compact 6-hole rack for a student workstation or a high-capacity 12-hole double-layer rack for a busy water testing laboratory, EduSupports has the right solution for your application.

Why Choose Our Wooden Nessler Tube Racks?
The wooden Nessler tube rack offers several distinct advantages over plastic or metal alternatives for colorimetric tube storage and organization.
First, its premium natural wood construction provides excellent strength, stability, and long service life. Unlike plastic racks that may warp or become brittle over time, wooden racks maintain their structural integrity for years.
Second, the polished clear varnish finish with low odor is specifically formulated for export markets. Unlike domestic versions that may have strong paint smells and visible wood knots, our export-grade racks feature carefully selected timber with minimal imperfections and a clean, professional appearance.
Third, the precision-matched hole diameters ensure a secure fit for specific Nessler tube sizes—17.6mm for 10ml tubes, 22mm for 25ml tubes, 27mm for 50ml tubes, and 32mm for 100ml tubes—preventing tipping or wobbling during use.
Fourth, the double-layer configuration provides enhanced stability for larger tubes (50ml and 100ml), with the upper and lower shelves working together to securely hold tall Nessler cylinders in place.
Fifth, the stable, heavy base prevents tipping, ensuring safety for valuable samples and glassware during color comparison procedures.
