Safety – Applicable to ALL Syringe Filters Syringe use can result in high pressure. The smaller the syringe, the higher the pressure that can be generated. As a general guide, the following pressures can be obtained by hand with the syringes indicated: • 20 ml-2 bar (30 psi) • 10 ml-3.4 bar (50 psi) • 5 ml-5.2 bar (75 psi) • 3 ml-6.9 bar (100 psi) • 1 ml-10.3 bar (150 psi) Individual users should determine the pressure they generate by hand with a specific size syringe and take appropriate safety precautions not to exceed the recommended rating for the device used. If the limitations are exceeded, the device may burst.
