Product Description
The round-bottom cylinder is the most traditional and widely used
liquid volume measuring instrument in the laboratory. Featuring a
classic rounded base design, the body is manufactured from high-quality
borosilicate glass 3.3 with clear, accurate graduations. Suitable for
solution preparation, sample measurement, and quantitative analysis.
Three Series · Flexible Selection
RichTech offers cylinders in round-bottom,
hexagonal-bottom, and plastic-base series:
1. Round-Bottom Cylinders
- Traditional round-bottom design.
- Suitable for routine laboratory liquid measurement.
2. Hexagonal-Bottom Cylinders
- Hexagonal base for stable, tip-resistant placement.
- Ideal for high-frequency use and applications requiring extra stability.
3. Plastic-Base Cylinders
- Glass body with plastic base and protective ring.
- Impact-resistant and breakage-reducing — especially suitable for teaching and frequent-use environments.
Graduation Options · Three Choices
RichTech offers three graduation technologies to meet different durability and precision requirements:
- White/Blue Printed Graduations (Standard): Fired with high-quality
ceramic ink at high temperature, clear and legible. Meets routine laboratory needs
with excellent cost-effectiveness.
- Copper-Red Printed Graduations (Premium Option): Fired with special
ceramic ink featuring a distinctive copper-red color. Resistant to acids, alkalis,
organic solvents, and chemical corrosion — does not fade or peel. Ideal for laboratories
handling corrosive reagents on a regular basis.
- Laser-Engraved Graduations (Premium Option): Permanently etched
into the glass surface using precision laser technology. Sharp, clear, and completely
wear-resistant — impervious to any chemical reagent. Perfect for high-frequency use,
long-term applications, and high-purity environments.
Design Features
- Rounded Base: Classic design with a smooth rounded bottom
for easy pouring and cleaning with no dead corners.
- Clear Graduations: White/blue printed, copper-red printed,
or laser-engraved options for quick and accurate volume reading.
- High Transparency: Pure, clear glass for easy observation
of liquid levels and color changes.
- Uniform Wall Thickness: Even thickness provides strength
and reduces breakage risk.
Material Advantage
Manufactured from Borosilicate Glass 3.3 in accordance with ISO 3585 standards.
The ultra-low coefficient of thermal expansion (3.3×10⁻⁶/K) ensures resistance
to thermal shock up to 280°C.
Quality Assurance
Every piece undergoes rigorous dimensional inspection, accuracy verification,
and visual inspection to meet high laboratory standards, providing reliable
performance for your experiments.
Note: Round-bottom cylinders have a rounded base and are
not designed for direct heating. Place on a level surface for accurate reading.
White/blue printed graduations are standard; copper-red printed and laser-engraved
graduations are premium options available upon request.
