\u30fb It is a hypoton (piknometer) wedon type referring to JIS R3503.
\n\u30fb Crude oil and petroleum product -How to seek density -suitable for picknometer methods.
\n\u30fb The capacity is about 50ml. <\/p>\n
\u25a0 Measurement method of density using Wordon specific gravity (reference to JIS K2249) 1) The mass (M0) of the specific gravity, plug and cap (M0) is applied to 0.1m digit. 2) Feel the sample in the specific gravity. The specific bottle containing a sample is immersed in a constant temperature tank that keeps it at 15 \u00b1 0.05 \u00b0 C to stabilize the sample temperature. Remove the bubbles to the sample surface and remove them. 3) When the sample temperature in the specific gravity is stable, insert the plug at 15 \u00b0 C in advance in the specific gravity. 4) Wipe off the excess samples attached to the plug, match the mennescas in the sample in the tube of the tube as the top of the plug, and immediately put the cap on the specific gravity. 5) Take the cap with the cap from the constant temperature aquarium, rinse the outside, wipe it with a pure cloth and dry. 6) After leaving the specific gravity bottle until it becomes room temperature, the mass (M \u25bc 15 \u25bd) is applied to the digit of 0.1m, and the density of the sample is calculated in the next equation. d \u25bc 15 \u25bd = \uff5b(m \u25bc 15 \u25bd -m \u25bc \u25bd 0) \u00d7 D \u25b2 15 \u25b3 W\/m \u25bc M \u25bc 15 \u25bd: Materials filled with samples at 15 \u00b0 C (g) m \u25bc 0 \u25bd: Mass bottle of empty, mass bottle of empty and caps (g) D \u25b2 15 \u25b3 W: 15 \u00b0 C.
