Kohlrausch Volumetric Flasks

What is it?

A Kohlrausch Volumetric Flask is a specialized laboratory volumetric flask designed for the accurate preparation and dilution of solutions, particularly where precise measurement of a defined liquid volume is required. It features a distinctive bulb-shaped body with a long, narrow neck and a calibrated graduation mark, providing excellent accuracy and easy observation of the liquid meniscus. Manufactured from high-quality borosilicate glass, it is suitable for analytical chemistry, pharmaceutical, research, and quality-control applications.

Key Features and Benefits

• Premium Borosilicate 3.3 Glass: Manufactured from chemically resistant borosilicate glass, offering excellent transparency, thermal stability, and resistance to commonly used laboratory chemicals.
• Precision Calibration: Accurately calibrated graduation mark enables preparation of solutions to a specific volume for reliable analytical measurements.
• Long Narrow Neck: The extended narrow neck provides improved control when bringing the solution precisely to the calibration mark and helps minimize measurement errors.
• Distinctive Kohlrausch Design: The specially designed bulb and neck provide convenient handling and efficient mixing of prepared solutions while maintaining accurate volumetric measurement.
• Clear Graduation Mark: A clearly defined calibration line allows easy and accurate reading of the liquid meniscus at eye level.
• Ground Glass Stopper: Supplied with a precision ground-glass stopper to help prevent contamination, evaporation, and accidental spillage during storage or mixing.
• Excellent Chemical Resistance: Suitable for preparing aqueous and many commonly used laboratory solutions without significant interaction between the glass and the solution.

Available Capacities

Kohlrausch Volumetric Flasks are available in a range of standard capacities to meet different analytical and solution-preparation requirements. Custom capacities, graduation specifications, and stopper configurations can be provided on request.

Applications

Widely used in analytical chemistry, pharmaceutical laboratories, research institutions, educational laboratories, quality-control facilities, and chemical testing laboratories for accurate solution preparation, dilution, standard solution preparation, and quantitative analytical procedures.

Quality Commitment: Every Kohlrausch Volumetric Flask is manufactured from high-quality borosilicate glass and carefully inspected for calibration accuracy, clear graduation marking, smooth finish, and proper stopper fit to ensure dependable performance in precision laboratory applications.
