Liquid Density Balance - Digital Liquid Densimeter - 0.001 g/cm3 Resolution, 5 Second Reading

The Master Science Liquid Density Balance joins the Archimedes displacement principle to modern electronics, so the density of a liquid appears directly on the digital display. A reading takes about five seconds, and only around 50 cc of sample is needed.

Compared with the traditional Westphal balance and pycnometer methods, the Master Science Liquid Density Balance needs no fiddly adjustment and is far less affected by outside factors and temperature. It is useful for quality management, cost control and formula research on products such as solvents, adhesives, paints, resins, chemical and edible oils, food additives, drinks and dairy products.

Key Benefits

• Direct density reading:: the Master Science Liquid Density Balance shows the value after one step.
• Fast:: about 5 seconds per measurement.
• Small sample:: roughly 50 cc is enough.
• Handles difficult liquids:: volatile, viscous, corrosive, strong acid and strong alkali.
• Easy cleaning:: open measuring cup with no narrow pycnometer neck.

For the U-tube oscillating method, see the Master Science digital density meter.

Product Features

Measurement

• Density value shown in one procedure, with rapid repeated measurements
• Digital display with high measuring accuracy; simple, stable and durable
• Samples from room temperature up to 100°C can be measured
• Works with a thermostatic bath to measure at a required temperature
• Quick measurement of volatile, corrosive and viscous liquids, strong acids and strong alkalis

Handling

• Convenient sampling: about 50 cc is sufficient
• No cumbersome set-up compared with Westphal balance and pycnometer methods
• Measuring cup is easy to clean and not limited by pycnometer neck size
• One-piece wind and dust cover for convenient, durable assembly
• RS-232C interface for connection to a PC or printer

Measuring Procedure

• Place the beaker with sample on the test board and tare the hook
• Hang the standard weight on the hook fully submerged in the liquid, then press ENTER to store; the density is displayed

Applications

The Master Science Liquid Density Balance is applied in:

• Chemical solutions and reagents
• Modern energy and oil fuels
• Fine chemical engineering
• Chemistry research laboratories
• Food, drink and dairy quality control

Standard Accessories Included

• Main unit
• Measuring frame
• Standard liquid measuring assembly (two stainless steel hooks, one glass weight, one glass beaker)
• Tweezers
• Thermometer
• 100 g weight
• Wind and dust cover

Common Problems This Balance Solves

Traditional liquid density methods are slow and delicate.

• Pycnometers are tedious to fill, weigh and clean:: an open beaker and one key press replace them.
• Viscous samples will not pass a narrow neck:: the displacement method has no such limit.
• Results have to be calculated by hand:: density is displayed directly.
• Aggressive liquids attack the hardware:: an anti-corrosive measuring assembly is available as an option.
