Neutral Oil and Loss Columns Apparatus for the determination of total neutral oil of natural fats and oils consisting of triglycerides and unsaponifiable matter.
•
Unique design of the flask allows the transfer of the weighed sample directly onto the column
•
Supplied complete, as shown
• Stopcocks have PTFE plugs, and the column has a 40-60 micron porosity fritted disc • Joints are Standard Taper 19/22 except for the extension tube, which is Standard Taper 7/25 • Ref: OACS Official Method Ca9f-57, JAOCS Vol. 46, No. 5, Pages 252-255 • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements Free fatty acids and miscellaneous non-fat substances are removed by passing the sample through a column of activated alumina. Losses are then calculated.
A short length of glass tubing aids in filling the buret through the tip by vacuum if desired. Stopper and tubing are not supplied.
