    II A has been issued. 3.2. Intended Use 3.2.1. General Description of the Component neMESYS devices are syringe pumps. They enable emptying and filling of syringes through a linear relative movement between a syringe holder and a piston holder.

  • Page 11: Proper Use

    3.2.2. Proper Use The neMESYS syringe pump system is intended for high-precision and pulsation- free dosing of fluids in a range from nanoliters to milliliters per second. Depending on the device being used, pressures in excess of several hundred bar may be reached.
  • Page 12 The information provided in the “Technical Data” section with respect to the maximum operating temperature must be observed. cetoni GmbH is not liable for potential impacts caused by the user extending the system with peripheral devices in a way that causes one or both of these values to be exceeded.

    6. Hardware Operation 6.1. Installing a Syringe The syringe holder on neMESYS modules allows the use of syringes with outside diameters of 6 to 30 mm and a maximum piston stroke of 65 mm. IMPORTANT Use high-quality glass syringes with outside diameters of 6 to 30 mm to guarantee precise flow rates.

  • Page 25: Fluidic / Valve

    6.2. Fluidic / Valve The neMESYS module can be fitted with an optional valve. This valve allows you to switch the syringe connector between your application (outlet) and a reservoir (intake), thereby enabling automatic refilling of the syringe.
  • Page 26 A FFKM membrane (shaded green area) connected to the rocker seals off the fluidic flow. The membrane also limits the valve’s operating pressure to 3 bar. CAUTION Please observe the maximum operating pressure of 3 bar to avoid damage to the standard valve. neMESYS Manual – Hardware Operation...
