Standard Infusion Only PHD 22/2000 Syringe Pumps

Note: The Harvard Apparatus PHD 22/2000 Advance Syringe Pump family will be discontinued in 2020. Our PHD ULTRA™ series of syringe pumps offer a superior touch-screen replacement for the PHD 22/2000 with improved accuracy and precision. The PHD ULTRA™ LCD color touch screen display and intuitive icon interface provide unparalleled ease of use so you can efficiently program simple to complex pumping methods without a PC. Please follow this link to see the comparable PHD ULTRA™ models.

The PHD 22/2000 syringe pump series gives you the lowest flow rates ever, the highest accuracy, the smoothest flow, advanced programmability from the keypad and yet, is very easy to use. 

• High accuracy and precision 
• Low flow rate 
• Ultimate flexibility and versatility 
• 2-year warranty 

Highest Accuracy and Precision
A welded steel chassis, machined Delrin™ components, upgraded guide rods, and advanced electronics give accuracy within 0.35% and reproducibility within 0.05%.

Lowest Flow Rates
A new micro stepping motor and control software give the lowest flow rates ever, down to 0.0001 µl/hour. It is also incredibly quiet so it won’t disturb your experimental subjects.

Versatility
There is a PHD 22/2000 syringe pump to meet every need, whether it be simple infusion, infusion and withdrawal, or programming capabilities. This page lists the infuse only version of this dynamic syringe pump family.This pump is suitable for applications that require high accuracy and low rates but, do not need to withdraw fluid and do not need programmability. Should you need withdrawal or program capabilities later on, the infusion only pump can be upgraded

Easy to Use
A bright, easy to read, two-line fluorescent display can be easily read from across the lab. A target volume key makes it easy to dispense a set volume. An ergonomic ‘Autolock’ release mechanism is easy for even small hands to operate and can never be left unlocked. The numerical keys utilize the familiar ‘telephone’ layout.

Upgrade
We offer pumps that can be upgraded. If you buy an infuse only pump and later decide you want programmability you can upgrade it. You pay a lot less than buying a whole new pump.

High Pressure Syringe Pumps
Every version of the PHD 22/2000 Pump is now available with a stronger motor that can provide more force. These pumps are ideal when working with viscous fluid or when driving multiple syringes. The standard force PHD 22/2000 series syringe pump delivers an average nominal force of 50 lbs. while the high power version delivers 66 lbs. If you require even greater force see the PHD 22/2000 HPSI or the Pump 4400 HPSI.
