Multiport Rotary Valves: Multiple-Source and Destination Selection
In multi-source fixed fluidics, connect the reagent for the current construction task in coordination with metering and resource interlocks. Record source, destination well and valve position together, with defined flushing after shared-path switching.
MRV3 selects sources or destinations and requires a port-state diagram and shared-volume budget. Port count indicates routing options; confirm pressure in each state and independent simultaneous supply requirements separately.
Define connections using the instrument's port-state diagram
This page covers multiport rotary valves. Mark every port, current source, receiving destination and branch requiring isolation, and check connections during aspiration, delivery, cleaning, maintenance and power loss. Valve selection must correspond to conditions permitting the drive action.
Include renewal of shared segments after switching in the sequence
After source switching, shared tubing may retain the previous composition. Record volume and arrival delay from the new source to the receiver, and measure residue and recovery for the actual worst-case switching combination. Confirm port positioning and arrival of new liquid separately.
Translate actual branch conditions into configuration requirements
| Condition | To confirm |
|---|---|
| Connections and pressure | Provide port diagrams and pressure conditions for all operating, cleaning and shutdown states. |
| Shared volume | Identify residue locations after source changes, flushing volumes and discharge destinations. |
| Control and isolation | Check valve-position feedback, pump actions, shutoff leakage and permitted power-off states. |
| Operation | Specific operating conditions |
|---|---|
| Path scheduling | Task state, sample or vessel identity, concurrent resources, interlocks and restart |
Compare product configurations by the roles on this page
| Product | Configuration option | Conditions to verify |
|---|---|---|
| MRV3 multiport rotary valve | Multiple-source selection | Compare 10-, 16- and 24-port options and port diagrams; verify high-pressure suitability separately |
Explore specific operating and validation tasks
Path scheduling
Confirm valve position together with reagent source and target well. Restart programs should preserve sample identity and completed-step records to prevent duplicate additions.
Confirm product roles in actual operation
| Operation | Measurements and observations | Priority checks |
|---|---|---|
| Path scheduling | Test concurrent operation, limiting states and complete fault recovery; verify that identities, cumulative quantities and records match actual actions | Resource conflicts, communication loss or mismatched identities can cause delivery to the wrong destination or repeated dosing. |
Assess per-well delivery, identity traceability and construct-development or screening results together.
Do more valve ports mean more channels can supply liquid simultaneously?
Check port connection structure and drive configuration. The number of selectable sources, independent paths and simultaneous-operation capability are different conditions, determined by actual connections in each state.
High throughput and multiple channels do not establish valid experimental results. See laboratory automation for shared workstation architecture.
