What is the fluid?

What is the Viscosity (cps)?

What is the Specific Gravity?

What is it comparable to? (i.e., gel, paste, water)

Does the viscosity change in relation to temperature?

Does the fluid contain any suspended particles?
If yes, please answer the following three questions:

What are the particles?

What is the particle size?

Can the fluid be heated to improve the dispensing or metering process?

If yes, to what maximum temperature (°C)?

What is the density of the liquid? (grams/cc)?

Does the fluid have entrapped air or other gas (contain bubbles)?

Can the fluid be degassed under vacuum to eliminate entrapped bubbles?

Are there any handling or environmental concerns? (MSDS required)

Are there any specific materials not compatible with the liquids being dispensed?

If dispensing, what volumes of fluid need to be dosed?

If metering, what is the flow rate range in milliliters per minute?

What is the accuracy requirement (+/- %)?

How many parts per minute do you need to fill?

Onto or into what is the dispense occurring?

How will the dispenser be triggered?
