BENTOCHECK (PROTEIN STABILITY TEST)
• Press READ and “----” will blink on the display. After a few seconds the instrument displays
the first reading. The meter continues updating the readings until the “Lamp and Read Status”
indicator turns off.
• The final displayed value is the averaged reading of turbidity in NTU. This is T2. Record the value.
• If “T2<T1+2” the wine can be considered stable. Otherwise the wine needs to be stabilized.
Note: to get more representative results of long term protein stability, HANNA Instruments®
recommends to filter the wine sample first through a 0.45 micron filter disc before analysis.
