L Series Split Beam UV-VIS Spectrophotometer

* Split beam opbcal system
* automatic wavelength settings
* 8 inch multi color touch screen
* automatic 8 position cuvette holder
* Automatic zero and lull scale adjustment
* Equipped with USB port
* Thermal plotter optional ·Software optional

Common Features
1: Legend series spectrophometers adopt split beam survey optical system, and blazed holographic gratings.They have outstanding test precision and very competitive prices.

2: 8-inch multi color touch screen, cutting-edge user interface, powerful functions, and easy operation.

3: The automated 8 position cuvette holder facilitates the operation under each measurement mode.

4: With powerful functions, the equipment shows great performance in qualitative and quantitative testing, such as:
·Full-spectrum scanning ·Linear regression
·Detailed spectrum scanning ·Concentration direct reading
·Time-based kinetics determination ·Peak/Valley detecting
·GOTO λ ·Multi-wavelength measurement

5: The equipment is designed with sophisticated power protection system.With high capacity of internal memory, it can store testing results, scanned images, regression equations and correction data.Therefore, it follows a fast initialization when power on.

6: The instrument can be connected with the dedicated printer, which can print testing results, or draw a curve from spectral scanning, fixed wavelength time-based scanning, and linear regression.

7: There is a USB port on the device, and UVwin8 software is optional to order.The device can be connected to a PC, which can not only enhance the performance in data testing and spectrum scanning but also expand the memory to save more testing results.
