Product Description

Our specific gravity bottles represent precision laboratory glassware designed for accurate density determination and specific gravity measurements. These bottles are manufactured to exacting standards and feature Class 'A' precision specifications, ensuring reliable results in analytical and quality control applications.

Each bottle features a ground standard neck with interchangeable PTFE (polytetrafluoroethylene) stopper, providing excellent chemical compatibility and long-term durability. The PTFE stopper resists a wide range of chemicals and solvents while maintaining an airtight seal essential for accurate density measurements.

Available in two certification variants—with standard calibration certificate and with NABL (National Accreditation Board for Testing and Calibration Laboratories) certification—these bottles accommodate diverse laboratory requirements. The NABL-certified variant ensures compliance with accredited laboratory standards and regulatory requirements.

All bottles include individual tolerance specifications for accurate volume measurement, enabling precise calculations of specific gravity values. The precision construction and quality assurance procedures ensure consistent, reliable results across multiple measurements.
