How to Order Custom Quartz Cuvettes

How to Order a Custom Cuvette?

Sometimes standard cuvettes don’t meet experimental needs. That’s where custom fabrication comes in. Qvarz has extensive experience producing custom quartz cuvettes for research labs and OEM instrument manufacturers.

1.1 Information to Provide

When requesting a custom cuvette, include:

• Path length (mm)
• Internal width and chamber volume
• Number of optical windows (2 or 4)
• Sealing requirements (open, screw-cap, septa, ports)
• Port specifications (e.g., M6-1 thread, custom connectors)
• Special coatings (anti-reflective, hydrophobic)
• Temperature or pressure requirements

1.2 Customization Process

1. Inquiry Submission
   • Researcher provides specifications, sketches, or CAD drawings.
2. Technical Review
   • Our engineers assess feasibility and suggest improvements.
3. Design Proposal
   • We provide drawings and dimensional tolerances for approval.
4. Fabrication
   • High-purity quartz is cut, polished, and assembled under precision conditions.
5. Quality Control
   • Path length and parallelism are measured, optical quality verified.
6. Delivery
   • Cuvettes shipped in secure, foam-lined packaging with QC documentation.

1.3 Typical Applications for Custom Cuvettes

• Pharmaceutical flow systems (continuous monitoring)
• Specialized fluorescence assays requiring unique geometries
• High-pressure studies (reinforced walls)
• OEM integration into analytical instruments

1.4 Lead Times & Costs

• Standard custom builds: 3–6 weeks
• Complex designs: longer, depending on fabrication steps
• Costs scale with precision requirements and number of units

2. Why Choose Qvarz Cuvettes?

There are many suppliers of cuvettes worldwide, but not all are equal. At Qvarz, we specialize exclusively in precision quartz fabrication for research-grade performance. Our cuvettes are trusted by universities, biotech firms, and industrial R&D labs that require uncompromising accuracy and reproducibility.

2.1 Manufacturing Precision

Every Qvarz cuvette is engineered with strict dimensional and optical controls:

• Path length tolerances as tight as ±0.01 mm, ensuring quantitative assays follow the Beer–Lambert law without hidden errors.
• Optical polish of λ/4 or better, which minimizes scattering and delivers high transmission across UV, visible, and near-IR ranges.
• Verified window parallelism to reduce baseline drift, eliminate refraction artifacts, and guarantee reproducible results between runs.

2.2 Materials & Quality

Qvarz cuvettes are made only from high-purity fused silica quartz, processed under clean manufacturing conditions to maximize clarity and consistency.

• Low-autofluorescence options are available for fluorescence spectroscopy, where sensitivity to weak signals is critical.
• Resistant to most solvents and acids, enabling use across diverse chemical and biological applications.
• Each batch undergoes quality checks for transmission spectra, parallelism, and polish before shipping.

2.3 Range & Customization

We provide a full range of quartz cuvettes to cover all laboratory needs:

• Standard models: 10 mm path length, available in 2-window and 4-window formats.
• Specialized designs: semi-micro, micro-volume, flow-through, long-path cuvettes for advanced applications.
• Custom fabrication: including threaded ports, temperature-control jackets, specialized coatings, and reinforced designs for high-pressure optical studies.

2.4 Support & Trust

Qvarz is not just a supplier—we are a partner for researchers and engineers.

• Trusted by top universities, biotech startups, and Fortune 500 R&D departments.
• Engineering support is available for custom projects, from prototyping to OEM integration.
• Clear quality control documentation is provided with every order, giving confidence in reproducibility.

Customer feedback highlights:

• “The consistency of Qvarz cuvettes made our DNA quantification reproducible across multiple labs.”
• “Our team needed a custom flow-through cell with threaded ports—Qvarz delivered within four weeks and integrated perfectly into our HPLC system.”

2.5 Speed & Reliability

We understand that research timelines are tight and experiments cannot wait.

• Fast lead times for both standard stock models and custom designs.
• Global shipping with protective packaging ensures safe arrival, even for fragile long-path cuvettes.
• Competitive pricing without compromising optical quality or material standards.

Conclusion: Choosing Qvarz means choosing precision, reliability, and long-term value. Whether you need standard 10 mm cuvettes, micro-volume cells for nucleic acids, or custom-engineered solutions for cutting-edge spectroscopy, Qvarz ensures that your data is built on the foundation of optical excellence.
