Burettes/Pipettes TRIZ Cases
- Array Plates with Hydrophobic-Hydrophilic Segmentation for Cell Washing
Segmented array plates use hydrophobic sample zones and hydrophilic wash channels to prevent cell loss during solution removal.
- Pipette Capacitive Touch Sensing for Contamination Prevention
A pipette uses a capacitive touch sense array to classify hand contact types and recognize gestures.
- Tapered Microfluidic Pipette Tip for Multi-Stage Bioanalysis
A tapered pipette tip integrates a microfluidic structure to perform sequential bioanalytical reactions using centrifugal forces.
- Microfluidic Cartridge Pneumatic Mixing and Gas Ventilation
A microfluidic cartridge uses a single compressible pump to drive fluid flow for particle resuspension without rotating parts.
- Pipette Tip Family with Integrated Plunger and Sensing System
An integrated plunger in the pipette tip eliminates air cushion errors while a sensing system ensures correct tip-pipette matching.
- Point-of-Care Diagnostic Cartridge Plunger Actuation
Plunger actuator compresses fluid dispenser to dispense precise reagent volumes, resolving diagnostic time versus accuracy trade-off.
- Pipetting Head O-Ring Clamping Mechanism
Deformed elastomer O-rings clamp pipette tips, reducing clamping force and user strain.
- Fluid Delivery Device with Blowing Element for Cross-Contamination Reduction
Segmented pipetting and gas blowing components resolve the contradiction between device complexity and cross-contamination risks in chemical assays.
- Pipette Tip Coupler Segmented Sealing and Axial Stop
Segmented coupling elements and an elastomeric O-ring reduce press force while maintaining an air-tight seal against the tip shoulder.
- Capillary Pipette with Air Bubble Chamber
A pipette uses a capillary tube and chamber to draw liquid by capillary action.
- Pipette Tip Rib Design for Low Ejection Force
Segmented seating ribs undergo partial plastic deformation to reduce ejection force and compensate for dimensional tolerances.
- Biaxially Oriented Pipette Mold Gas Permeable Apertures
Vacuum forming with gas-permeable mold apertures eliminates raised witness features that obscure graduation markings.
- Syringe Mechanical Coupling for Chromatography Purity
Radial locking elements engage a recess on the coupling segment to eliminate adhesive contamination and ensure fluid purity in solvent environments.
- Disposable Frustoconical Flow Cell for Non-Destructive Particle Analysis
A disposable frustoconical flow cell enables non-destructive liquid sample analysis by minimizing internal surface contact.
- Integrated Pipette Display for Microplate Guidance
An integrated pipette display indicates the next target well location code, reducing manual pipetting errors and space requirements.
- Pipette Tip Capillary Tube Small Volume Sample Collection
A pipette tip uses a narrow capillary tube to collect fixed liquid volumes for automated clinical analysis.
- Pipette Tip with Embedded Electrodes for Depth Control
Embedded electrodes on the pipette tip measure fluid resistance to provide real-time feedback, eliminating errors from inconsistent liquid levels.
- Pipette Tip Rack Plate Projections for Vertical Orientation
Internal projections and counter-bores in a pipette tip rack plate restrict lateral displacement, preventing static-induced skewing during shipment.
- Liquid Measuring Piston with Pressure Relief Port
A piston-driven variable-pressure chamber enables self-contained liquid measurement and removal without external tools.
- Superamphiphobic Pipette for Mass Loss Reduction
A pipette with a superamphiphobic surface captures liquid droplets using generated electric charges.
