Volumetric flask AVF series

with flat-bottompear-shapedamber glass

Short description
A volumetric flask is a precise laboratory container used to prepare solutions of known concentrations. Featuring a flat bottom, pear-shaped body, and a long, narrow neck, these flasks are calibrated 'to contain' (TC) at 20°C. Manufactured in Amber Class A from Borosilicate 3.3 glass for superior chemical resistance and UV protection. Each flask includes a durable PE stopper for a secure, leak-proof seal.

Technical compliance

• Glass Standards: Manufactured using high-quality Borosilicate 3.3 glass for superior thermal shock resistance and chemical durability.
• Metrology Standards: Designed to comply with applicable standards such as ISO 1042, ASTM E288 and USP.
• UV Protection: Produced with a controlled iron-sulfur composition to shield light-sensitive reagents from radiation in the 200–450 nm range.
• Traceability: Available with a Batch Certificate or a serialized Individual Work Certificate for strict laboratory documentation.

Precision and Protection
Specialized amber coating with controlled iron-sulfur composition protects samples from UV radiation between 200 nm and 450 nm. This protection is essential for pharmaceutical testing and photochemical reactions.

Material and Accuracy
Crafted from premium Boro 3.3 borosilicate glass to ensure thermal shock resistance and chemical durability. Class A calibration provides the precision required for analytical chemistry. Graduations remain accurate and legible across the available sizes.

Usage and technique

• Preparation: Ideal for making standard solutions by dissolving a solute and bringing the volume up to the mark with a solvent.
• Dilution: Used to accurately dilute a concentrated solution to a specific volume.
• Technique: Align the meniscus with the etched graduation mark; use a pipette for the final, critical drops to maximise precision.
