noack evaporation loss

This method covers the determination of evaporation loss of lubricating oils. An oil sample is heated to 250°C and an air stream is passed over its surface for 1 hour under vacuum. The evaporation loss is calculated from the loss in weight of the samples.
The equipment comprises of…
A well-insulated Aluminum heating block with electric heating and microprocessor based digital temperature controller and digital timer.
1 evaporation crucible of stainless steel with stainless steel lid assembly.
Lifting handle and tools.
2 glass bottles with ground stoppers, set of angular glass pipes, hose connectors, rubber stoppers and 2 meters of silicon hose.
1 Metal rack with inclined manometer of range 0 – 30mm of H2O with bleed valve for manual regulation of air stream.
1 electric vacuum pump with vacuum regulator.
Power supply : 230 ± 10% Volt AC, 1 Phase, 50 Hz.
