Lasany LI-2900 Double Beam UV-VIS Spectrophotometer for Regulated Laboratories
The Lasany LI-2900 Double Beam Microprocessor UV-VIS Spectrophotometer is an analytical laboratory instrument designed for measuring absorbance, transmittance and concentration across the ultraviolet and visible wavelength regions. It combines double-beam optics, microprocessor control, a colour touchscreen and analytical software to support laboratory research, pharmaceutical testing and quality control workflows.
With a manufacturer-listed wavelength range of 190–1100 nm and a spectral bandwidth of 1 nm, the LI-2900 supports a variety of spectrophotometric measurement applications. Its touchscreen interface and software-assisted analysis can help laboratory personnel operate the instrument, review spectra and manage measurement data.
For laboratories working under regulated quality systems, the instrument may be evaluated for use within a validated analytical workflow. However, 21 CFR Part 11 compliance depends on the supplied software, system configuration, validation and applicable procedures. Buyers should obtain written confirmation of the exact compliance capabilities before purchasing or representing this product as Part 11 compliant.

Software Requirements for Regulated Laboratories
Laboratories evaluating the LI-2900 for regulated use should confirm that the exact supplied software and complete system support the controls required by their procedures and applicable regulations. Relevant capabilities may include:
- Unique user accounts and role-based access permissions
- Secure electronic records and data retention
- Computer-generated, time-stamped audit trails
- Electronic signature functionality where required
- Record review, export and retrieval controls
- System validation documentation and change control
- Data backup, recovery and protection against unauthorised alteration
These are verification requirements, not confirmed standard features of the LI-2900. Confirm them with the manufacturer or authorised supplier before making a compliance claim.
Applications
- Pharmaceutical research and quality control
- Chemical analysis and concentration measurement
- Biotechnology and compatible DNA/protein analysis workflows
- Environmental and water sample testing
- Food and beverage laboratory analysis
- Academic and scientific research
- Industrial testing and quality assurance
- Validated laboratory procedures where the complete system meets applicable requirements
Benefits for Research and Quality Control
The Lasany LI-2900 brings double-beam optics, touchscreen operation and software-supported analysis together in a benchtop UV-VIS instrument. Its broad wavelength range and multiple measurement modes make it suitable for varied analytical workflows in research and quality control laboratories.
For regulated environments, instrument suitability should be determined by evaluating the complete system, including software, computer configuration, data management procedures and validation documentation. Instrument specifications alone do not establish 21 CFR Part 11 compliance.
Ordering and Compliance Verification
Before ordering this model for a regulated laboratory, request written confirmation of the supplied software version, electronic record controls, audit trail functionality, electronic signature support where applicable, validation documents and any additional hardware or licensing requirements.
