Both the features and the syringe capacity of the PHD22/2000 syringe pumps from Harvard Apparatus can be upgraded without purchasing a new pump
The PHD 22/2000 series is available in several models: infusion only, infusion/withdrawal or programmable.
These pumps can accommodate four, six, or ten plastic, glass or stainless steel syringes with the addition of a multi-rack.
The standard rack accommodates two syringes.
Feature upgrades are performed at the Harvard Apparatus factory, but syringe rack upgrades can be performed by the user with the purchase of an upgrade kit.
The PHD 22/2000 series is accurate to +/-0.35% and offers a broad flow rate range from 0.0001ul/hr to 220ml/min.
These units accommodate syringes ranging from 0.5ul to 140ml making it very versatile.
