SYRINGE PUMPS
PHD 22/2000 Advanced Syringe Pumps
32
Over forty years ago Harvard Apparatus perfected the leadscrew
principle and created the first syringe pump. Since that time, tens
of thousands of Harvard Apparatus pumps have earned a reputation
as the most reliable research pumps in every major laboratory in the
World. The PHD 22/2000 syringe pump series gives you the lowest
flow rates, the highest accuracy, the smoothest flow, advanced
programmability from the keypad and yet, is very easy to use. It is
also incredibly quiet so it won't disturb your experimental subjects.
Configurations
This pump is available as a
standard, push/pull, remote, high
pressure, or with multi-racks.
Upgrade
We offer pumps that can be upgraded. If you buy an infusion/
withdrawal pump and later decide you want programmability you
can upgrade it, see page 33.
