Sampling probes focus on aspiration and dispensing. Piercing probes provide liquid access through films, stoppers or sealed consumables, requiring review of tip strength, piercing angle and venting.
Custom Piercing Probes for Sealed Consumables
FOREACH custom piercing probes provide liquid access through films or stoppers in sealed reagent reservoirs, sample containers and consumables. The probe is designed around the target consumable, piercing depth and motion path in the automated instrument.
Design options include tip angle, cutting-edge orientation, side ports, vent holes or grooves, bends and mounting ends. Review the gas and liquid paths together with consumable thickness, penetration force, probe strength and aspiration position.
Provide consumable drawings or samples, fluid details, cycle timing and installation space. Probe materials, welding and surface processes are confirmed for the project. Validate piercing stability, liquid access and venting with the actual consumable and instrument motion.
Typical Applications:
Film piercing, Stopper piercing, Reagent-chamber aspiration, Sample-chamber aspiration, Venting support, Fluid paths for sealed consumables
Customization requirements
Share the fluid, interfaces, available installation space and operating requirements so we can help define a suitable custom solution.
Product information
For accessing liquid through films, stoppers or sealed consumables. Define the material to pierce and the motion before selecting the tip, liquid inlet and venting path.
Tip, side ports, vent holes or grooves, bends and welded features are evaluated for the consumable and motion. Not every version includes all features.
Customization checklist
| Item to confirm | Details to check |
|---|---|
| Drawings or samples | Provide consumable drawings, film/stopper samples, a piercing-position drawing or installation-space information. |
| Material to pierce | Confirm the material, thickness and structural strength of the film, stopper, reagent/sample chamber or sealed consumable. |
| Tip geometry | Confirm the tip, cutting-edge orientation, tip angle, strength and surface treatment against piercing resistance. |
| Venting design | For vent holes, grooves or side ports, confirm the gas/liquid paths, vent direction and aspiration sequence. |
| Mounting and motion | Confirm penetration depth, motion direction, target aspiration position, mounting end and internal instrument space. |
| Manufacturing feasibility | Evaluate side ports, bending, welding, polishing and plating against tube dimensions, tip geometry and piercing stability. |
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 consumable and seal geometry, piercing position, tip orientation, penetration depth, liquid and vent openings, mounting datum and motion envelope. 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.
