Eisco Labs: 5mL Class A Amber Volumetric Flask with Stopper

This 5mL amber volumetric flask is expertly crafted from durable 3.3 borosilicate glass, providing superior chemical resistance and thermal stability for rigorous laboratory applications. Featuring Class A precision and TC (to contain) calibration, it ensures exceptional accuracy with a tight ±0.025mL tolerance, ideal for precise analytical measurements. The amber glass construction effectively minimizes UV and visible light exposure, protecting sensitive chemicals and solutions from degradation. Each flask includes a secure 10/19 polyethylene stopper and a permanent QR code, offering quick digital access to individual calibration certificates and verification data. Compliant with ASTM E1042 standards and autoclavable at 121°C, this flask is perfectly suited for demanding analytical, pharmaceutical, and chemical laboratories requiring reliable volumetric accuracy.

• FLASK AND STOPPER INCLUDED || 5mL amber volumetric flask made from borosilicate 3.3 glass; includes interchangeable polyethylene stopper with 10/19 joint for secure closure. Features a QR Code for checking certifications.

• DARK AMBER GLASS MATERIAL || Amber-colored glass reduces light transmission, suitable for use with photosensitive contents during storage and handling in light-exposed environments.

• CALIBRATION AND TOLERANCE || Class A tolerance of ±0.025mL conforms to ASTM E1042 standards; calibrated to contain (TC) with permanently marked QR code for tracking.

• COMMON LAB APPLICATIONS || Suitable for solution preparation, titration, and volume-sensitive dilution tasks in chemistry, analytical, or pharmaceutical labs.

• AUTOCLAVABLE AND DURABLE || Resistant to thermal stress, chemical exposure, and autoclaving at 121°C; low expansion 3.3 borosilicate supports long-term use.
