Overview & Features
Highest Accuracy Class (Class A): Each flask is individually calibrated in accordance with the To Contain (In) volumetric method at the standard reference temperature of 20°C, ensuring maximum reliability with an exceptionally low tolerance of only ±0.40 mL.
Heavy-Duty Borosilicate Glass Construction: The entire flask body is molded from thick-walled, high-clarity borosilicate glass with a low thermal expansion coefficient, providing excellent thermal shock resistance and outstanding chemical resistance against most strong acids and alkalis.
Single White Calibration Mark: The long tapered neck is integrated with a sharp white circular calibration line, enabling technicians to accurately observe and align the bottom meniscus, minimizing parallax errors during volume adjustment.
Large Octagonal PE Stopper: Supplied with an octagonal Polyethylene (PE) stopper fully compatible with the 24/29 ground glass joint. The tight-sealing design ensures complete protection against solvent evaporation and provides excellent leak-proof performance during inversion and mixing operations.
ISO/GLP-Compliant Quality Assurance: Each flask is permanently marked with a durable white enamel Batch Number on the glass body, supporting routine calibration control and full traceability in internationally standardized laboratory environments.
