Description
VLMB15 Bubble Free Flow Cell is a high-performance quartz flow cell specifically engineered for fluorescence applications where stable signal, continuous flow, and minimal bubble interference are essential. With a 10 mm optical path length and a 1500 μL sample volume, it is ideally suited for medium-volume flow analysis in spectroscopy, biotechnology, and analytical research.
This model uses molded fabrication, providing outstanding optical clarity, smooth inner surfaces, and dimensional precision. Its bubble-free design effectively eliminates trapped air, improving signal stability and repeatability for high-sensitivity measurements.
Molded Fabrication Features
- Superior optical transmission and highly precise surface finish.
- No adhesives are used — ensuring clean, inert, and stable flow channels over long-term use.
- Excellent chemical resistance — tolerates almost all acids, bases, and organic solvents that do not react with quartz, including toluene and acetone (HF is the only major exception).
- Thermal stability up to 1200 °C for short-term and 600 °C for continuous use.
- Overcomes typical limitations of fused cuvettes, such as seam staining and reduced solvent compatibility.
- Best suited for clean, stable, high-sensitivity analytical environments.
Typical Applications
- Fluorescence spectroscopy with continuous flow
- Liquid chromatography detector flow cells
- Biological and chemical assay systems requiring stable optical signals
- High-precision optical measurements in research and OEM instruments
Key Features
- 10 mm optical path length with 1.5 mL volume capacity
- 4 clear optical windows for fluorescence excitation and detection
- Quartz tubing (OD 5 mm / ID 3 mm) for secure and stable fluid connections
- Bubble-free structure ensures stable and reproducible signal
- UV/VIS compatible (190 – 2500 nm)
