BIOCHROM WPA Biowave II UV/Visible Spectrophotometer

• Quantification of nucleic acids (DNA, RNA) and proteins in molecular biology and biochemistry.
• Measurement of cell density in microbiology and cell culture laboratories.
• Kinetic assays to monitor enzyme activity or reaction rates.
• General UV/Visible absorbance and transmission measurements for various chemical and biological samples.
• Purity assessment of biological samples by measuring absorbance ratios.

Wavelength Range

Typically 190–1100 nm, covering both UV and visible spectra.

Sample Volume

Units of this type commonly accommodate sample volumes as low as 10 µL, particularly with appropriate cuvettes.

Light Source

Often features a long-life Xenon lamp for extended performance and energy efficiency.

Detector Type

Commonly employs a high-resolution CCD array for rapid and accurate data acquisition.

Optical Design

Typically uses a monochromator with a holographic grating, providing robust and stable measurements.

Power Supply

For this class of equipment, a standard laboratory power supply, typically 100-240V AC, 50/60 Hz, is required.

Data Output

Commonly includes USB for data export and may feature an integrated printer or PC connectivity.
