FOREACH 16-channel ceramic rotary selector valve for reagent selection and wash-path switching
FOREACH MRV3-D16 is a 16-channel ceramic rotary selector valve for integration into automated equipment. It supports reagent selection and wash-path switching in instrument fluidics and laboratory automation systems, working with a pump and the equipment control program to select reagent or wash-fluid connections in sequence.
The valve uses a zirconia stator and sapphire rotor, with motor-driven rotation to switch fluid paths. PEEK or PCTFE valve-head configurations allow wetted materials to be selected for the reagents, cleaning fluids and operating conditions.
For integration, use the flow diagram to establish connection requirements, then check bore size, port threads, internal volume and mounting requirements. Material combinations and specifications depend on the selected ordering model.
Typical Applications:
Reagent selection, Sample preparation, Sequential liquid distribution, Fluid-path flushing

Typical Applications
MRV3-D16 supports instrument workflows that need to switch automatically between liquid connections: selecting reagents, changing sample-processing steps or directing liquid to different destinations. The valve selects the connection, the pump moves the liquid, and the instrument program coordinates the sequence.
Analytical Instruments: Sequential Reagent Selection
An analytical method may require several reagents to be added in sequence. Connect the reagent reservoirs to separate channels so the valve can select the required reagent before the pump delivers it to a reaction vessel or detection unit.
MRV3-D16 provides the switching step so reagent connections can follow the analytical method. Allocate channels for both reagents and cleaning fluid; the paired pump and instrument program control the delivered volume and speed.
Sample Preparation: Switching Between Sampling, Reagents and Washing
Before analysis, a sample-processing sequence may require sample transfer, addition of processing liquids and washing of the connected tubing. Each step uses a different liquid connection and must be coordinated with pump aspiration and delivery.
MRV3-D16 can select sample, processing-liquid or wash connections in the required sequence. When samples pass through the valve, consider particles, material adhesion and the permitted residue between samples when designing the workflow.
Automated Liquid Distribution: One Supply, Multiple Destinations
When several vessels or instrument locations use the same liquid, a distribution valve can select their supply connections in sequence. After the pump completes delivery through one channel, the valve selects the next channel for the following delivery.
MRV3-D16 provides channel switching for this sequential supply arrangement. The instrument controls delivery volume, dwell time and order, while the channel count must accommodate the intended destinations and spare connections.
Repeated Operation: Flushing Between Reagents
When different reagents pass through shared tubing, a wash step can be included between reagent changes. Connect cleaning fluid to a channel, select it after the previous reagent step and use the pump to flush the valve and tubing before selecting the next reagent.
Include this wash step in the automated operating sequence. Set the amount of cleaning fluid and number of flushes according to tubing length, reagent properties and acceptable residue, then check the result using the actual liquids.
