Highest Accuracy and Precision
The PHD ULTRA
TM
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.
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
TM
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.
Pump Models
The PHD ULTRA
TM
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 user-
defined 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.
