The following list is a guide to common syringes and their associated
diameters and surface area. Syringe diameter data, in mm, is listed
below for each syringe. All Harvard Apparatus microprocessor syringe
pumps require the user to input syringe diameter information. The
pump uses this diameter data to set flow rates. The PHD 22/2000
series of syringe pumps also has this information built into the pump
memory in a handy Syringe Look Up Table. Surface area information
was used to calculate PSI (pounds per square inch) data for the
pressure on page 111. Average pressures for any syringe pump
and syringe combination can be calculated by dividing the average
(nominal) syringe pump force by the syringe diameter (in square
inches) to obtain PSI. Example, nominal pressure obtained using a 25
ml Hamilton Gastight
®
Syringe on a PHD 22/2000 standard pressure
syringe pump would be: 50 lbs / 0.644 in2 = 77.6 PSI (5.35 bars).
