High pressure notes:

The NE-4000 produces about 15 lbs (7.5 lbs/syringe) of linear force at top speed and about 100 lbs (50 lbs/syringe) at slow speeds. 10 mL/hr is an example of slow speed. The pressure that can be generated is relative to the syringe size. On a 60 mL syringe, this would roughly produce about 30 psi.
