Product Description
Professional-Grade Glassware for Precise Lab Results
Elevate your laboratory standards with our 20-piece set of High-Quality Round Bottom Test Tubes. Expertly crafted from premium borosilicate glass (ASTM E 982 Specification), these tubes are designed to meet the rigorous demands of professional scientific environments, advanced educational settings, and discerning hobbyists.
Why Choose Our Borosilicate Test Tubes?
Standard soda-lime glass often leaches precipitates that alter the pH of sensitive samples. Our tubes utilize high-grade borosilicate glass to significantly reduce pH changes and sample contamination, ensuring the integrity of your critical experiments.
Key Features & Specifications:
- Precise Dimensions: 20mm Outer Diameter x 200mm Height, perfectly sized for standard racks and centrifuges.
- Optimal Capacity: 45ml volume suitable for a wide range of sampling and reaction applications.
- Robust Construction: Features uniform wall thickness (1.0-1.2mm) and a classic round bottom design.
- Thermal Resistant: Superior thermal stability allows for safe use with heating mantles and Bunsen burners without the risk of immediate thermal shock.
- Chemically Inert: Ideal for pH-sensitive samples and culturing due to low alkali content.
Common Applications:
Perfect for chemistry labs, biological culturing, sample storage, mixing solutions, and decorative scientific display. Durable, reliable, and built to last.
