PYCNOMETERS

Designed for measuring and comparing the densities or specific gravities of liquids and solids.

·         15123N series thermometers are non-mercury spirit-filled; 15123R series thermometers are mercury-filled

·         Supplied with Standard Taper 10/18 thermometer with a range of 14 to 38 degrees C in 0.2 degree increments

·         Thermometer is retested for accuracy within ± 0.2 degrees C

·         Standard Taper 5/12 side tube cap has a small vent near the top

·         Body is conical for maximum stability

·         Capacity is within 10 percent of nominal shown on the flask

·         Each flask body is numbered for ready identification

·         The 50mL size may be used to obtain the specific gravity of pigments (ASTM D153)

• Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements                                                                        

Procedure for Use of 15123R and 15123N  Bottles

1. Thoroughly clean, dry, assemble, and weigh the empty pycnometer and record.

2. Fill with recently boiled, distilled water at a temperature a degree or two below the determination temperature.

3. Insert thermometer into the bottle, forcing water through the overflow tube.

4. Place in a constant temperature bath and when the desired temperature is reached, wipe off excess water from the overflow tube tip and cap.

5. Remove from bath, wipe dry, reweigh and record.

6. Weight difference is that of the water in the flask - the volume of the pycnometer may be calculated.

7. Repeat process with liquid of an unknown specific gravity and record the weight difference.

Calculation:

Specific Gravity = (weight of liquid of unknown S.G.)
