中文名稱: 美國KIMAX比重瓶 50ml
英文名稱:Specific Gravity Bottles, Pycnometer, Serialized
規格:Weight 47g, H 186mm
•錐形瓶身可保持量測時的最大穩定度
•附一支水銀溫度計，溫度範圍攝氏14-38度，刻度0.2 度
•側管蓋子近上方處有一個小出氣孔
•使用方法請參考下面說明
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 ± 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---
•Thoroughly clean, dry, assemble, and weigh the empty pycnometer and record.
•Fill with recently boiled, distilled water at a temperature a degree or two below the determination temperature.
•Insert thermometer into the bottle, forcing water through the overflow tube.
•Place in a constant temperature bath and when the desired
temperature is reached, wipe off excess water from the overflow tube tip and cap.
•Remove from bath, wipe dry, reweigh and record.
•Weight difference is that of the water in the flask — the volume of the pycnometer may be calculated.
•Repeat 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)
