Automated microfluidic fluid handling module (SPM) by AMF

AMF’s SPM is suited for microfluidic automation, by design. The optimized space between the rotary valve and the syringe dramatically reduces the internal volume of the module and leads to optimized carryover volumes. AMF SPM offers an optimal flow rate, proficiently diluting samples or reagents from milliliters down to nanoliters. It aspirates or dispenses liquids, controls the flow rate, and prepares complex mixes. This versatile tool can efficiently switch between air and liquid samples, ensuring no leakage due to its superior sealing capabilities.

As an OEM product, the SPM is highly customizable so as to meet the specific needs of your experiments

Wetted Material: The rotary valve’s wettedmaterial is PCTFE (for the valve head), PTFE (valve rotor) and borosilicate glass (for the syringe) ensuring robustness and broad chemical compatibility.
Channel Diameter: 500 µm to 1000 µm. The conjunction of small internal channel size with the unique AMF geometry allows it to reach extremely low internal volumes which can go as low as 600 nL*. This particular attribute optimizes your operation time, saves material (reagents, test materials and samples) and leads ultimately to reduced cost of operations for your final microfluidic application or instrument.
Number of Ports: up to 12 radial ports. The valve’s number of ports will give you the ability to handle multiple fluids (from 6 to 12) within your microfluidic device (or detection chamber) and/or manipulate multiple fluids (sample to be tested, reagents, gases).
Syringe volume: 500 µL to 1000 µL. Our high-precision syringes are made of borosilicate glass while the plunger is made of PTFE, making our device compatible with biological samples and a wide range of chemicals.

Advanced Microfluidics unique microfluidic SPM design:

Integrated sensor: the position sensor is directly integrated into the valve rotor (1) to ensure precise valve positioning and internal channel alignment between the rotor and the stator (1). An automatic procedure at power-up alerts the valve of its precise location.
For your motor, choose between the fast model for a port switching speed as low as 150 ms and the low power model to reduce power consumption for better portable device integration and smaller power supply.
Easy to use: the valve head (stator + rotor (1) + syringe (2)) can be easily removed and exchanged for preventive maintenance services. Our SPM is designed to be compatible with standard connectors widely used in microfluidics and beyond.
High precision syringe pump (2)

*Our unique precise valves exhibit an internal volume (port-to-port) down to 600 nL (for a 4 ports switch valves) due to their exceptionally small 0.25 mm diameter channels.
