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.
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.

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.
3.2.6. Safe Operation Measures 3.2.6.1 Electromagnetic Emissions The neMESYS syringe pump system is designed for usage in any facility directly connected to a public supply network that also supplies buildings used for residential purposes.
The devices left our facilities in perfect condition and may only be opened by cetoni GmbH. If a device is opened by an unauthorized person, all warranty and liability claims shall be void, in particular those referring to personal injury.

There is a danger of damaging the housing or sealing material. Before using the valve for the first time, please check the chemical compatibility of the media you want to use with the PEEK housing material and the FFKM (perfluoroelastomer) sealing material. neMESYS Manual – Technical Data...
When used properly the device is maintenance-free. Should you encounter problems that you cannot fix yourself or which require opening the device, please contact cetoni GmbH to discuss further actions. The device may only be opened by cetoni GmbH or authorized service staff. Violating this rule will void the warranty.
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.

The syringe position can be varied somewhat by shifting the piston holder. To do that, loosen the screw with a 4mm Allen wrench. neMESYS Manual – Hardware Operation...
Page 24
Put the clamping piece back on and insert the adapter plate matching the piston diameter in such way that the piston head sits between the piston holder and the adapter plate. neMESYS Manual – Hardware Operation...
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.

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...
Please observe the correct placement of the valve plug. The white area should face the valve, while the rocker should point away from the valve. Rocker You can then simply lift the valve to remove it. neMESYS Manual – Hardware Operation...

Activating the coil in the valve for an extended period of time causes the coil to heat up, which, in case of low flow rates, may warm up the medium flowing through the valve. Lowering the valve voltage after switching lessens this heating-up effect. neMESYS Manual – Electrical Interfaces...
