TOQUARTZ® Solving Challenges with Custom-Slot Quartz UV Cuvette
Custom-Slot Quartz UV Cuvettes for Automated Spectrophotometer Systems
Key Advantages
-
Slot width tolerance within ±0.05mm
Ensures seamless insertion into auto-sampler trays with zero jamming or misalignment. -
Optical centerline deviation <0.1mm
Maintains consistent path length across batches, reducing calibration drift in automated systems. -
Dimensional repeatability >98.5% across 500-unit batches
Supports high-throughput workflows with minimal rejection rate and no manual adjustment.
TOQUARTZ® solution
A German spectrophotometer OEM reported a 17.8% rejection rate using generic cuvettes due to slot misalignment in auto-samplers. After switching to TOQUARTZ® Custom-Slot Quartz UV Cuvettes with ±0.05mm slot tolerance and <0.1mm optical deviation, rejection dropped below 1.2%. This improved assembly efficiency and reduced instrument recalibration frequency by 40%.
Custom-Slot Quartz UV Cuvettes for Micro-Volume Sample Analysis
Key Advantages
-
Minimum sample volume down to 45μL
Enables accurate analysis of scarce biological samples without dilution or waste. -
Slot geometry optimized for capillary action
Ensures uniform sample distribution and eliminates air bubble interference in low-volume assays. -
Signal-to-noise ratio improved by 2.7× vs. standard 1mL cuvettes
Enhances detection sensitivity in dilute DNA/protein solutions.
TOQUARTZ® solution
A Canadian biotech startup conducting RNA quantification faced 30% sample loss using standard 1mL cuvettes. TOQUARTZ® delivered custom-slot cuvettes with 0.5mm path length and 45μL capacity. This reduced sample usage by 85% and improved fluorescence signal stability by 2.4×, enabling reliable results from limited-volume clinical samples.
Custom-Slot Quartz UV Cuvettes for Multi-Channel Fluorescence Detection
Key Advantages
-
Dual-beam slot design with 90° emission window alignment
Maximizes excitation-emission efficiency in orthogonal fluorescence setups. -
Optical window flatness <λ/10 at 633nm
Minimizes signal distortion and ensures high-fidelity fluorescence readouts. -
Customizable 4- or 6-window configurations
Supports simultaneous multi-channel detection in high-throughput screening platforms.
TOQUARTZ® solution
A US-based fluorescence plate reader manufacturer required a 4-window cuvette for simultaneous excitation/emission at multiple angles. TOQUARTZ® delivered a custom-slot design with λ/10 flatness and 0.1mm tolerance. Compared to their previous supplier, signal intensity improved by 38%, and integration time per assay was reduced by 22%, accelerating their product launch by 5 weeks.

Usage Guide of Custom-Slot Quartz UV Cuvette
Handling Procedures
- Always handle cuvettes using gloves to prevent fingerprints and contamination
- Hold cuvettes by the frosted or non-optical surfaces to avoid scratching optical windows
- Avoid placing optical surfaces directly on laboratory benches or hard surfaces
Cleaning Instructions
- Clean immediately after use to prevent sample residue from drying
- Use mild detergent solutions followed by ultrapure water rinses
- For organic residues, use appropriate solvents (acetone, ethanol) followed by thorough rinsing
- Optional ultrasonic cleaning for persistent contaminants (2-3 minutes maximum)
- Air dry in a dust-free environment or use filtered compressed air
Storage Recommendations
- Store in original protective packaging or dedicated cuvette holders
- Keep in a clean, dust-free environment
- Avoid contact between optical surfaces during storage
- Maintain at room temperature in low-humidity conditions
Performance Verification
- Periodically verify dimensional stability with precision measurement tools
