Benefits for Laboratory Applications
The Lasany LI-721 provides a practical option for laboratories that require basic visible spectrophotometric measurements without a bundled software package. Its manual wavelength control and multiple photometric modes support straightforward routine testing. It is suitable for laboratories that can perform measurements directly on the instrument and do not require software-based data analysis.
Ordering and Configuration Information
Before ordering, confirm that the quotation specifies the LI-721 without software. Verify the supplied sample cells, power cable, dust cover, operating manual, RS232 cable and warranty. The manufacturer’s published LI-721 page describes the instrument and its specifications but does not clearly document a separate official “without software” SKU, so confirm the exact configuration with the supplier.
