Volumetric Flask Amber Class-A DIN/ISO

Volumetric flask made of high quality, heavy duty 3.3 borosilicate glass. Amber color for light sensitive compounds. Single, white graduation mark. Class .

A volumetric flask / measuring flask / graduated flask is a kind of laboratory flask, calibrated to hold an accurate specific volume at a specific temperature. Volumetric flasks are used for accurate dilutions and preparation of solutions and any other liquids needed at the laboratory workflow.

One of the main benefits of using amber glass is that it provides the best protection against UV light, blue light, and other light wavelengths under the 450-nanometer range. UV rays can cause what is known as photooxidation

Key Features:

• Compliance: Fully complies with DIN/ISO 1042 standards.
• Material: High-quality Borosilicate 3.3 glass, providing exceptional thermal and chemical resistance.
• Amber Coating: A uniform amber stain is applied to the exterior, ensuring the contents are shielded from light degradation.
• Accuracy: Calibrated "to contain" (TC, In) at 27°C (or 20°C upon request) with tolerances strictly as per Class A limits.
• Stopper: Usually supplied with an interchangeable ground glass stopper (Series 58) or a chemical-resistant PE stopper.
• Printing: Features high-contrast white enamel markings for easy reading against the dark amber background

• Batch Certificate: Documents the mean volume, standard deviation, and date of issue for the entire production lot.
• QR Code Access: Many modern OMSONS amber flasks feature a QR code on the body for instant digital download of the certificate.

• Light-Sensitive Reagents: Preparation of solutions like silver nitrate, potassium permanganate, or iodine which decompose when exposed to light.
• Vitamins & Pharmaceuticals: Handling photosensitive vitamins (e.g., Vitamin A, B12) and light-degradable active pharmaceutical ingredients (APIs).
• Analytical Chemistry: Used in labs requiring high precision (Class A) and protection for sensitive standards.
