Biochrom’s Libra S4+ visible spectrophotometer is ideal instrument for education and QC laboratories. It is compact, lightweight and ergonomically designed for simpler applications. There is a large display for ease of reading, simple user interface for rapid set up and analysis.
It measures absorbance, % transmission and concentration as well as simple kinetics. The large display allows the user to view results in numerical value as well as a graphical view. The user can view the peak, zoom in and out all on the unit.
Up to 72 methods can be stored providing the user a quick and easy way to recall frequently used methods. These methods can also be locked using a pin protected password, as well as unlocked and deleted.
The S4+ provides the ability to label your sample for easy identification. Your sample can be measured in a test tube using the optional test tube cell holder accommodating test tubes that are 10 to 18 mm in diameter. A heated cell holder is also available for thermostatted measurements at 37°C.
Data Output
PVC (Print Via Computer) software is included with the instrument providing the user with the option to transfer data directly to a PC. Data can be easily stored on a USB memory stick and analyzed at a later date
