Measure Your Chocolate with ATAGO VISCO Digital Viscometer

Measure Your Chocolate with ATAGO VISCO Digital Viscometer

Looking for a reliable and convenient viscometer to measure your chocolate? We got you covered!
 
Let’s go down to tips on measuring chocolate using ATAGO VISCO Digital Viscometer:
 

Tip #1: Selecting the best suitable spindle

Let's imagine how melting chocolate is. It's obviously more viscous than water, but less viscous than honey. 

Let this diagram help you with this:
 

 
VISCO has three spindles A1, A2, A3.
Let's try spindle A2.
 

 
For chocolate, let’s use the disposable paper cup for more convenience. The disposable paper cup is equivalent to the L beaker. So now we’ll set the combination as “A2L” (Spindle A2 and L Beaker combination).
 

Tip #2: Selecting the best suitable speed

Let's try lower speed at first at 12rpm.
 
Don’t forget to jot this all down for your record:
 
Spindle A2
Beaker size L
Speed 12rpm
 
NOW START!
 
Result:
 
Time 60 sec 120 sec 180 sec
Viscosity (mPas) 23,737 23,598 23,555
Torque (%) 75.6 75.2 75.1
Temperature (°C) 38.7 38.1 37.4
 
Tips: Torque % should be within 10-100%.
 
Let’s try using a different spindle, A3.
 
Spindle A3
Beaker size L
Speed 12rpm
 
Result:

 
Time 60 sec 120 sec 180 sec
Viscosity (mPas) 23,386 24,095 23,959
Torque (%) 25.3 25.1 24.9
Temperature (°C) 40.3 39.9 39.5
 
Note: Spindle A1 did not work with chocolate since its viscosity is high. Please refer the first diagram regarding tips to choosing beaker and spindle for your sample.
 
You can try with different speeds and time too! VISCO has the auto stop function where you can set how long you would like to measure at a time. The measurement will automatically stop according to the time you set (e.g., 30 seconds).
 

Tip #3: Recording results every 10 seconds
 
Spindle A3
Beaker size L
Speed 30rpm
 
Result:

 
Time 10 sec 20 sec 30 sec 40 sec 50 sec 60 sec
Viscosity (mPas) 12,933 12,921 12,914 12,902 12,894 12,886
Torque (%) 35.5 33.5 33.5 33.5 33.4 33.4
Temperature (°C) 41.2 41.1 41.1 40.9 40.8 40.7
 

Tip #4: Notes and Small tips for Beginners
  • Viscosity usually goes down as time passes due to frictional heat. If the sample is heated, its viscosity goes down.
  • To prevent drastic decrease of temperature, heat the cup adapter by immersing into hot water.
