Syringe Selection Guide - Harvard Apparatus

1 11,000 Specialty Products to Enhance Your Bioresearch1 Syringe Selection GuideSpecialized Tools for BioresearchThe following list is a Guide to common syringes and their associateddiameters and surface area. Syringe diameter data, in mm, is listedbelow for each Syringe . All Harvard Apparatus microprocessor syringepumps require the user to input Syringe diameter information. Thepump uses this diameter data to set flow rates. The PHD 22/2000series of Syringe pumps also has this information built into the pumpmemory in a handy Syringe Look Up Table.

2 Surface area informationwas used to calculate PSI (pounds per square inch) data for the pres-sure table on page A93. Average pressures for any Syringe pump andsyringe combination can be calculated by dividing the average (nomi-nal) Syringe pump force by the Syringe diameter (in square inches) toobtain PSI. Example, nominal pressure obtained using a 25 mlHamilton Gastight Syringe on a PHD 22/2000 standard pressuresyringe pump would be: 50 lbs / in2= PSI ( bars).Hamilton Gastight - 4000 and 5000 Glass10 Monoject Plastic1 Glass2 Plastic3 All & Sons Perfectum Syringes and Their DiametersVolumeDia.
