Syringe Pumps PHD ULTRA™ Advanced Syringe Pumps SYRINGE PUMPS PHD ULTRA™ Advanced Syringe Pumps Highest Accuracy and Precision The PHD syringe pump family has a superior fluidics drive mechanism which assures ease of use and high performance, for the smoothest, most accurate flow rates of any syringe pump. Flow rates of 1.50 pl/min to 216.0 ml/min are accurate within 0.25% and reproducible within 0.05%. A microprocessor-controlled, small step angle stepper motor drives a lead screw and pusher block. Advanced micro-stepping techniques are employed to further reduce the step angle to eliminate flow pulsation. ULTRA™ Pump Models The PHD ULTRA™ Pumps are available in three configurations designed for different operating environments and varying degrees of operational flexibility. Infusion Only: This model supports infusion operations at userdefined flow rates and with selectable target volume or time values to control the total infusion volume. The Infusion Only models do not include programmable, user-defined Methods. Infusion/Withdrawal: This model supports infuse only, withdraw only, infuse/withdraw and withdraw/infuse operations at user-defined flow rates and with selectable target volume or time. Users can create and store one Method up to 800 steps. Infusion/Withdrawal Programmable: This model supports infuse only, withdraw only, infuse/withdraw and withdraw/ infuse operations. Users can create and store multiple Methods of up to 800 steps on the pump. Maximum Experimental Versatility This pump can be oriented vertically or horizontally for optimum experimental connectivity. This pump comes standard to hold 2 syringes, but can be purchased with 3 other syringe racks: 6/10 syringe rack, 4 x 140 ml syringe rack and 4 x microliter syringe rack. Syringe racks can be ordered separately. Multi-syringe racks provide multi-channel operation or serve as a large capacity reservoir. Syringe Racks • • • • The standard 2-syringe rack holds 2 syringes from 0.5 µl to 140 ml The 4 x 140 multi-rack holds four 60 ml or 140 ml plastic syringes only 6/10 multi-rack will hold up to 10 syringes from 0.5 µl to 20 ml and up to 6 syringes from 30 ml to 60 ml The microliter syringe rack independently holds 4 syringes, from 0.5 µl to 10 ml, enabling syringes of different sizes to run simultaneously. Easy-to-Use Interface The PHD ULTRA™ Syringe Pumps are very easy to use with an LCD color touch screen and icon interface. The Message Area of the touch screen is used to display helpful instructions for the currently displayed screen. It is also used to display error or warning messages to indicate problem conditions in a Method or error conditions during pump operation. The Run Screen shows all of the pump parameters on one screen for easy review. 20 Harvard Apparatus phone 508.893.8999 toll free U.S. 800.272.2775 fax 508.429.5732
