Frequently asked questions

Is the cuvette factory new?

Yes, this Unico Black Square Quartz Cuvette is supplied in Factory New condition. This assures you that the cuvette is brand new, guaranteeing optimal performance and measurement integrity for precise photometric analysis, particularly across the wide 170 nm to 2500 nm UV and Visible Light spectrum.

Does the cuvette support a broad wavelength range?

Yes, the Unico Black Square Quartz Cuvette is specifically designed for broad-spectrum analysis, making it highly versatile for laboratory use.

It operates across a wide wavelength range, covering both the Ultraviolet (UV) and Visible Light spectrum:

  • Minimum: 170 nm
  • Maximum: 2500 nm

This expansive range is possible due to the cuvette’s durable Quartz construction, which ensures high optical clarity and is ideal for demanding UV measurements.

What are the available capacity options?

The Unico Black Square Quartz Cuvette is available in two precise capacities designed to accommodate various sample volume requirements:

  • 0.48 ml Capacity: This is the standard option, suitable for typical spectroscopic measurements. The corresponding 10 mm path length variant is often configured as a flowcell.
  • 0.07 ml Capacity: This is a specialized micro-volume option, ideal when the sample material is highly limited or precious, ensuring accurate readings with minimal volume.
Is the cuvette a standard, fixed height?

Yes, this cuvette maintains a fixed exterior height of 48 mm.

This standard dimension is essential as it ensures proper alignment and compatibility when used with designated spectrophotometer mounts for UV/Visible light analysis.

Does this cuvette offer a wide wavelength range?

Yes, the Unico Black Square Quartz Cuvette is engineered for exceptional optical performance across a wide spectrum, covering both UV and Visible Light ranges.

Key compatibility details:

  • Broad Wavelength Range: This cuvette is effective for measurements from 170 nm up to 2500 nm, providing versatility for various spectroscopic applications.
  • Optimal Material: Its Quartz construction is crucial for high-precision optical analysis, ensuring high transmission and clarity, especially in the demanding UV region.

This makes it an ideal component for laboratory or research environments requiring high-precision spectrophotometry.

Does the cuvette support a broad wavelength range?

Yes, the cuvette is engineered from high-quality Quartz to ensure exceptional performance across a wide spectral range, providing great versatility for analytical requirements. This range covers both Ultraviolet (UV) and Visible Light spectrophotometry.

  • Operational Wavelength Range: 170 nm to 2500 nm
Is the high-quality quartz construction durable?

Yes, the Unico cuvette is built using precision-grade quartz, offering reliable performance and high durability essential for accurate spectroscopic analysis. Its construction ensures longevity even in demanding laboratory environments.

  • Material Resilience: Quartz provides inherent chemical resistance and physical resilience, making it suitable for continuous laboratory use and compatibility with various reagents.
  • Quality Assurance: The cuvette is guaranteed to be Factory New and is backed by a 1 Year Warranty, ensuring it meets strict technical specifications right out of the package.
Is high-quality quartz used?

Yes, the Unico Black Square Cuvette is constructed from high-quality quartz material, which provides optimal optical performance crucial for sensitive measurements.

Key benefits of using quartz include:

  • Broad Spectral Range: Quartz enables measurements across the full UV and Visible spectrum, supporting wavelengths from 170 nm up to 2500 nm.
  • Optical Integrity: It offers the high clarity and durability needed for precise quantitative analysis.
  • Stray Light Shielding: The transparent quartz optical pathway is paired with an opaque black base designed to block lateral light and ensure measurement accuracy.
What are the interior dimensions for the 0.48 ml cuvette?

The Unico Black Square Quartz Cuvette with a 0.48 ml capacity features precise internal dimensions of 10 mm x 4 mm x 12 mm. This size is generally recommended for standard spectrophotometry applications.

What are the available volume sizes?

The Unico Black Square Quartz Cuvette is offered in two distinct volume sizes, both made from durable Quartz and optimized for the broad spectral range of 170 nm to 2500 nm (UV and Visible Light).These capacities cater to different sample handling requirements:

  • 0.48 ml Capacity: This larger option is suitable for standard sample volumes. The detailed interior dimensions are specified as 10 mm (width) x 4 mm (depth) x 12 mm.
  • 0.07 ml Capacity: This low-volume variant is ideal for applications that require minimal sample usage, helping to conserve precious reagents or samples.
