Description

This micro-volume cuvette (Type 51B / 52B) features black walls and two clear optical windows, designed to significantly reduce stray light and improve measurement sensitivity.

Compared to standard cuvettes, this design:

• Minimizes optical interference
• Enhances signal-to-noise ratio
• Improves accuracy in low-concentration measurements

The black-wall structure blocks unwanted light reflections, which is critical for high-precision UV-Vis analysis.

These models offer different internal geometries and volumes, allowing users to select the most suitable configuration for their experimental setup.

Applications

• UV-Vis spectroscopy with ultra-low sample volume
• Trace analysis and low-concentration measurements
• Biological and chemical sample testing
• High-sensitivity analytical applications

Key Features

• Black walls to suppress stray light and improve accuracy
• Two clear optical windows for transmission measurements
• Micro-volume design for precious or limited samples
• Multiple configurations (Type 51B / 52B) for different applications

Available Materials

• Quartz (190–2500 nm)
• IR Quartz (250–3500 nm)
• Optical Glass (340–2500 nm)

Specifications

Typical configurations include 10 mm path length with micro-volume design, suitable for high-sensitivity UV-Vis measurements.

Comparison with Type 50B

• Type 50B: standard ultra-low volume configuration
• Type 51B / 52B:
  
  👉 optimized internal geometry for improved measurement performance
  
  👉 more flexibility in experimental setup

Comparison with Other Micro Cuvettes

• Standard micro cuvette: basic measurement, higher stray light
• Frosted wall cuvette: reduces reflection, moderate stability
• Black wall cuvette : maximum stray light suppression + highest sensitivity
