Withdrawing Sample Devices TRIZ Cases
- Concave Top Plate for Gloved Microbial Air Sampling
Concave sidewalls give gloved operators a positive grip and make the top plate easier to lift during clean-room sampling.
- Flared Specimen Collection Tube With Adhesive Seal
A flared member guides specimens into a tubular body, then folds and adheres over the opening to limit contamination and fluid permeation.
- Depth-Resolved Sequestered Carbon Estimation From Soil Cores
Soil cores collected near root systems are analyzed across depth to improve the precision, repeatability, and affordability of carbon estimates.
- Continuous Soil Fluid Concentration Mapping During Implement Movement
Continuous pumping and GPS-linked sensing map soil-fluid concentrations beyond limited point-based core sampling.
- Controlled-Chamber Odor Detection for Temperature and Humidity Stability
A controlled chamber regulates target-gas temperature, humidity, and flow to improve odor detection accuracy and reliability.
- Hydrophilic Ionic Liquid Formulation for Deformation-Free Tissue Clearing
See how a hydrophilic ionic liquid matches tissue refractive index to clear samples without deformation while preserving fluorescence.
- Food Quality Indicator With Porous Ink For VOC Detection
A porous substrate carries reactive ink while gas-permeable, liquid-blocking layers enable low-cost VOC freshness monitoring.
- Syringe-Shaped Sample Preparation With Binding-Matrix Purification
A syringe-like device uses a sample-binding matrix for binding, washing, and eluting analytes without centrifugation.
- Odor Detection Chamber with Temperature and Humidity Control
A controlled chamber stabilizes target-gas temperature, humidity, and flow for more accurate, stable odor sensing.
- Wick-Based Perfume Atomizer for Controlled Volatility Testing
A defined wick-to-volume ratio and airtight mixing compartment control perfume delivery, limiting volatility and alcohol saturation.
- Elastic-Contact Liquid Collector for Complete Small-Volume Capture
An elastic contact member and multiple flow passages help capture small liquid volumes completely before transfer to a visible container.
- Tissue Section Transfer With Hydrogel Force Mediation
A hydrogel intermediary reduces direct contact forces during tissue-section transfer, helping preserve sample integrity across repeated handling.
- Single-Plane Sampling System for Lower Mechanical Complexity
Multiple-axis specimen tube analysis is simplified with a single-plane traverse that lowers cost, failures, and footprint.
- Integrated Blood Collection Structure for Microliter Testing
A capillary collection rod connects to testing and buffer chambers, reducing sample handling, operator exposure, and blood volume.
- Contactless Filter Collection for Inhalable Dose Dissolution
A contactless quick-release filter unit limits particle agglomeration during transfer, supporting reproducible inhalable-dose dissolution testing.
- Porous Frit Filtration for Rapid Lateral Flow Sample Preparation
Conventional slurry filtration is slow and messy; positive pressure drives samples through a porous frit for clean lateral flow testing.
- Optimized Sorting Gates for Particle Analyzer Measurements
Particle analyzers use preliminary measurements and an analysis layer to generate gating strategies that improve sorting accuracy and data-analysis efficiency.
- Non-Belt Train Sampling System for Moisture-Sensitive Materials
Moisture-driven bulking, sieve blockage, mixing, and moisture loss are addressed with belt-free transport and integrated sample preparation.
- Electrochemical Airborne Pathogen Detection with Collector Airflow
An airflow pump concentrates airborne pathogens on a collector for electrochemical sensing, enabling real-time detection without laboratory analysis.
- Frangible Sample Transfer Device for Contamination Control
A frangible section separates the contaminated collector from the handle, reducing operator exposure and transfer contamination.
