One liquid is more viscous than the other hence it is hard to dispense equal amounts of both liquids with the attached syringe system. I had to disconnect the two syringes to get equal amounts of both.

Response from Chris at Thorlabs: The liquids themselves do have differing viscosity, so a small amount of one may pour out before the other when you initially push in the plunger. But this will balance out quickly as you push in the plunger. Both sides are identical, so movement of the plunger should dispense an equal volume.
