Wash probes support external washing, internal flushing, waste aspiration and residual-liquid removal to reduce carryover, droplet retention and cross-contamination risk.
Custom Wash Probes for Automated Analyzers
FOREACH custom wash probes integrate into automated analyzer wash stations for external probe washing, internal flushing, waste aspiration and residual-liquid removal. The configuration is developed around the wash-fluid and waste-fluid paths.
Single-head, dual-head, multi-head, side-port and bent configurations are matched to the available space and cleaning sequence. Hole position, size and direction are coordinated with the target wash area, waste outlet and aspiration direction.
Provide wash-station drawings, wash and waste-fluid compositions, flow, cycle timing and service-life requirements to review welding, polishing, coatings and surface treatments. Validate wash coverage, residual liquid and carryover control in the complete cleaning process.
Typical Applications:
External probe washing, Internal probe flushing, Waste aspiration, Residual-liquid removal, Wash-station integration, Carryover reduction
Customization requirements
Share the fluid, interfaces, available installation space and operating requirements so we can help define a suitable custom solution.
Product information
For internal/external probe washing, waste aspiration or residual-liquid removal. Separate wash-fluid supply from waste recovery before defining ports, channels and installation space.
Single-, dual- and multi-head, side-port and bent designs are customized for the wash station. Supply, spray washing and aspiration functions must be assigned to the correct channels.
Customization checklist
| Item to confirm | Details to check |
|---|---|
| Drawings or samples | Provide the wash-station drawing, probe installation space, wash-fluid path and waste-path description. |
| Washing task | Confirm whether the task is sample-/reagent-probe washing, external washing, internal flushing or waste aspiration. |
| Spray-port geometry | Confirm side-port count, diameter, position, jet direction and target area with the wash motion. |
| Waste-removal design | Confirm waste outlets, residual-liquid recovery, aspiration direction and waste-tray position against the station design. |
| Probe arrangement | Customize single-, dual- or multi-head arrangements, bends and mounting ends for the wash-station space. |
| Residue-reduction processing | Confirm welding, polishing, coatings and droplet-reduction treatments against wash/waste fluids and service-life requirements. |
This page outlines customization options and the details to confirm. Materials, dimensions, tolerances, surface treatments and operating conditions are governed by the agreed drawings, samples and inspection requirements.
Drawings and supporting documents
- Design drawings or samples
- Show the surface to be washed, wash-station space, supply and waste channels, port orientation, required coverage, mounting datum and motion clearances. Provide 2D drawings, 3D files or physical samples. If the information is incomplete, start with the installation space and a description of the task.
- Operating and acceptance requirements
- Specify the actual fluids, wash procedure, instrument motions and acceptance method. Confirming dimensions and validating operation in the instrument are separate checks.
- Design revision and delivery documents
- Drawings, inspection requirements and accompanying documents are agreed for each project. Dimensions, labels or accessories shown in example photos do not define the supply scope for every version.
