Description
The Class A Amber Trapezoidal Base Volumetric Flask from Osmosis Scientific is a premium laboratory flask engineered for ultra-accurate solution preparation, dilution, and quantitative analysis. Manufactured from high-grade Boro 3.3 borosilicate glass, this flask offers exceptional resistance to chemical attack and thermal shock — making it ideal for analytical laboratories, research facilities, pharmaceutical QC, and educational environments.
The trapezoidal base design improves stability, minimizing the risk of tipping during routine lab use while providing a secure, flat surface during measurement and handling. The amber tint shields light-sensitive solutions from harmful UV and visible light exposure, preserving sample integrity and analytical reliability.
Calibrated to Class A accuracy, this volumetric flask meets rigorous laboratory standards, ensuring precision when preparing standard solutions or performing volumetric analyses. Each flask includes an individual calibration certificate that demonstrates traceability and quality assurance.
The etched calibration line and included PE stopper support accurate filling and secure sealing during preparation and storage. Available in capacities from 10 ml up to 2000 ml, this flask accommodates a broad spectrum of laboratory requirements — from small-volume analytical workflows to larger solution batching.

Frequently Asked Questions (FAQs)
Amber glass blocks approximately 90% of UV light and visible light wavelengths below 500 nm. This protects photosensitive reagents, pharmaceuticals, and analytical stapromoting solution stability and accuracy over extended storage periods.
Osmosis Scientific amber volumetric flasks are available from 5 mL to 2000 mL in standard capacities, with corresponding NS ground-glass joints (10/19, 12/21, 14/23, 19/26, 24/29, 29/32).
No. Amber volumetric flasks are designed for room-temperature solution preparation and storage. Do not heat above 60–80 °C, as this can affect glass properties and alter calibration. For heating, use standard volumetric glassware or reaction flasks.
