Eisco Volumetric Flask, QR Coded, AMBER

Description

• CALIBRATION QR CODE ON FLASK || Scan the QR code printed directly on the body of the flask to retrieve a PDF of the calibration batch certificate. Works best if you hold the flask over a solid black background.
• INDUSTRIAL STRENGTH || Made of high quality, heavy duty, borosilicate 3.3 glass. It is microwavable and autoclavable, and can withstand high temperatures and thermal shocks.
• 25mL CAPACITY || Flask has a 25mL capacity and features a single white graduation mark. Class A tolerance, ±0.040mL. Mouth has an 8.5mm inner diameter. Flask size: 1.63″ diameter x 4.5″ tall.
