Spectrofluorometer

High Sensitivity, Bench-Friendly Spectrofluorometer at an Accessible Price

Measure absorption, transmission, fluorescence emission, and fluorescence excitation

A compact spectrofluorometer that ensures reliable optical measurements with consistent alignment between components. With a total footprint of less than 30cm x 30cm, the Ossila Spectrofluorometer fits on any lab bench or worktop to provide a complete stand-alone fluorescence.

The two integrated light sources support different measurements. The hyperspectral white LED is well-suited for absorption, transmission, and fluorescence excitation measurements, while the UV light provides excitation light for fluorescence emission measurements. Both sources have adjustable output power, short warm-up times, and longer lifetimes than traditional fluorescence spectroscopy light sources. On the detection side, the two integrated single-pixel silicon photomultipliers (SiPMs) with active temperature correction are more sensitive than standard photodiodes and offer a wide dynamic range. The sample holder can be rotated in indexed 22.5-degree increments. The integrated filter holders, meanwhile, allow bandpass filters to be easily inserted into the beam path.

The system is designed as a low cost option for small labs that are otherwised priced out of calibrated, purpose-built systems. With the Ossila Spectrofluorometer, you can get reliable spectroscopy data at an affordable and upfront price, without blowing your research budget or compromising on performance with a DIY set up.

Spectrofluorometer Software

The Ossila Spectrofluorometer software provides a user-friendly interface for setting measurement parameters and acquiring data, allowing for precise control of fluorescence (excitation and emission), absorbance, and transmission measurements.

Control each component individually to identify experimental parameters, take preliminary measurements, and diagnose issues. The results panel makes it easy to plot, display, save, and analyze your data. For absorbance and transmission, the separate measurement tabs mean you just set your parameters and press go. For excitation fluorescence measurements, you can choose the best light source set up for you; use the UV LED or choose an individual wavelength from the tunable light source.

Assign reference measurement and automatically perform necessary calculations for each measurement type.
Automatically perform background calculations which are applied to your measurements.
Perform periodic measurements (also known as kinetic series).
Save data and settings to .csv files and keep your data save with the autosave function.

Standalone Spectrofluorescence System

Consistent Alignment, Confident Measurements

With a system that is both affordable and high quality, you can move away from DIY setups that compromise the reliability of your results. In a standalone, integrated instrument, you can take advantage of the multiple measurement configurations offered by the two integrated light sources: a hyperspectral white LED and a high-power UV light source.

Flexible Setup in One System

Included as standard, the simple software make it convenient to switch between measurements, without having to reconfigure the component setup, using the tab interface. Plus, you can measure the optical properties of both thin films and liquids with the flexible sample chamber and interchangeable holders. For additional customization, adjust your sample rotation and add bandpass filters to the measurement pathway.

Built for Small Spectroscopy Labs

To protect your workflow, it is easy to fit this spectrofluorometer, with a footprint of less than 30 cm x 30 cm, onto your work bench amongst your existing equipment. And this small system comes with a small price tag. Designed to be much more affordable than alternative systems, the Ossila Spectrofluorometer is accessible to smaller research groups.
