Optimal Design for Precision Testing

With its laboratory-grade, chemical-resistant borosilicate glass construction and stainless steel fittings, the Vacuum Pycnometer is engineered for accuracy and durability. The oil-less diaphragm vacuum pump and analog vacuum gauge ensure precise pressure monitoring and easy operation, allowing for consistent and reproducible test results while maintaining a safe and reliable working environment.

Easy Operation & Maintenance

The manual control system simplifies operation, requiring no direct speed specification. Setup and cleaning are straightforward thanks to the smooth glass surfaces and robust construction. Accessoriesincluding vacuum tubing, pump, and pycnometer flasksare included, supporting convenient, leak-proof operation. Its bench-top mount and manageable weight suit any well-equipped laboratory.

Versatile Applications in Bitumen Testing

The Vacuum Pycnometer is specifically designed for bitumen laboratory testing, determining maximum specific gravity in uncompacted paving mixtures. Its capacity to handle up to four specimens simultaneously increases productivity and repeatability for research facilities, manufacturers, and quality control labs concerned with road construction and paving material analysis.

FAQs of VACUUM PYCNOMETER:

Q: How does the Vacuum Pycnometer determine the specific gravity of bituminous mixtures?

A: The Vacuum Pycnometer uses a controlled vacuum environment to measure the volume and mass of bituminous paving mixtures. By creating a near-perfect vacuum (up to 30 mm Hg), air is removed from the sample, enabling accurate measurement of its theoretical maximum specific gravity using the 1-liter volumetric flask.

Q: What are the primary benefits of using borosilicate glass and stainless steel fittings in this equipment?

A: Borosilicate glass offers excellent chemical resistance and durability for laboratory use, while the stainless steel fittings provide corrosion resistance and robust leak-proof operation. This combination ensures longevity, safety, and easy maintenance of the pycnometer even with frequent chemical exposure.

Q: When and where is the Vacuum Pycnometer typically used?

A: This equipment is commonly used in civil engineering laboratories, paving material research facilities, and quality control departments during the evaluation of bituminous mixtures. It is especially relevant before the construction phase, ensuring materials comply with standards for maximum specific gravity.

Q: What process is involved in using the Vacuum Pycnometer?

A: To operate, the sample is placed into the pycnometer, which is sealed with its rubber gasket and connected to the oil-less diaphragm vacuum pump. The operator manually applies a vacuum, monitors the pressure with the analog gauge, and after equilibrium, takes measurements to calculate specific gravity.

Q: What sample size and throughput does the pycnometer support?

A: Each pycnometer flask holds up to 1 liter of sample, and the system can handle up to four specimens at once, allowing the testing of up to 4000 grams per cycle. This design increases laboratory throughput and efficiency.

Q: How is the equipment maintained and cleaned?

A: Maintenance is straightforward: after testing, the borosilicate glass containers and stainless steel fittings can be easily cleaned using standard laboratory detergents. Ensure all rubber gaskets and hose connections are checked regularly for wear to maintain leak-proof operation.

Q: What are the usage advantages of this Vacuum Pycnometer for bitumen testing?

A: The advantages include quick response time (under 5 seconds to reach vacuum), high accuracy (0.01 gm/cm), simultaneous specimen testing, robust chemical resistance, and reliable manual operation, making it a valuable tool for consistent and accurate bitumen analysis in any quality-focused lab.
