JSB0802 automatic paraffin light stability tester

This instrument is suitable for the determination of light stability of paraffin wax, fully refined paraffin wax and semi-refined paraffin wax for food, in line with SH/T0404 standard.

1. Method outline

The sample plate filled with melted wax was placed in a constant greenhouse and irradiated for 45 minutes under the conditions of ultraviolet illumination of 12.0± 0.3mW /cm2 and temperature of 90±1℃, then the color of the sample was determined. The color number indicates the light stability of paraffin wax.

II. Main technical parameters

Model specification: JSB0802

Irradiation temperature: 90±1℃
