In the laboratory, selecting the right glass coefficient is critical for balancing performance and budget. Thousand Peak Glass offers a complete spectrum of Lab Glassware ranging from High Borosilicate 3.3 (for extreme heat) to Neutral Borosilicate 5.0/7.0 (for storage and disposables). Whether you need heavy-duty beakers for heating or millions of disposable culture tubes for automated lines, we provide the exact material grade to meet ISO and ASTM specifications without over-engineering your costs.
High Borosilicate 3.3 (The "Pyrex" Standard): The premium choice. Essential for glassware that will be heated directly (beakers, flasks). It offers the highest thermal shock resistance and chemical inertness.
Neutral Borosilicate 5.0 (USP Type I): The "Workhorse" of the lab. Excellent chemical stability (same acid resistance as 3.3) but at a lower cost. Ideal for Sample Storage Vials, Chromatography, and Reagent Bottles where extreme heating is not required.
Borosilicate 7.0 (Low Expansion): The cost-effective solution for Disposable Test Tubes and Culture Vials. It is far superior to Soda-Lime glass but more affordable than 5.0, making it perfect for single-use biological applications.
