KIMAX bottle is supplied with a special medium length 10/18 thermometer with a range of 14 to 38 degrees C in 0.2 degrees. Retested for accuracy within ¡Ó 0.2 degrees C. Cap for the side tube is medium length 5/12 and has a small vent near the top. Body is conical for maximum stability, and capacity is within 10 percent of nominal shown on the flask. The 50 mL size is used to obtain the specific gravity of pigments (ASTM D153).
---Procedure for Use of 15123R Bottle---
¡EThoroughly clean, dry, assemble, and weigh the empty pycnometer and record.
¡EFill with recently boiled, distilled water at a temperature a degree or two below the determination temperature.
¡EInsert thermometer into the bottle, forcing water through the overflow tube.
¡EPlace in a constant temperature bath and when the desired
temperature is reached, wipe off excess water from the overflow tube tip and cap.
¡ERemove from bath, wipe dry, reweigh and record.
¡EWeight difference is that of the water in the flask ¡X the volume of the pycnometer may be calculated.
¡ERepeat process with liquid of an unknown specific gravity and record the weight difference.
---Calculation:---
Specific Gravity = (weight of liquid of unknown S.G.) / (weight of water at same temperature)
