The Vernier Flash Photolysis Spectrometer is a simple, user-friendly device for demonstrating the fundamental principles of chemical kinetics and photochemistry to undergraduate chemistry students. It measures the absorption and emission changes over time of a photoexcited sample at a single wavelength, which is determined by a filter (600 nm filter included).

Description
Photochemical reactions are very important in many areas of chemistry with applications including photodynamic therapy and solar energy harvesting. These reactions often proceed quickly and, as a result, require fast reaction techniques to analyze. The Vernier Flash Photolysis Spectrometer is a simple, user-friendly transient absorption spectrometer. It is useful for demonstrating the fundamental principles of these types of fast, photo-catalyzed reactions. Some experiment ideas include kinetics of photochemical reactions such as
- Excited-state dynamics
- Triplet-decay analysis
- Time-resolved phosphorescence
- Phosphorescence-quenching kinetics
- Isomerization
- Reactive free radicals
- Photocatalysis

The concept of chirality can be difficult for students to visualise. Go Direct Polarimeter provides a visual representation of this concept by measuring the optical rotation of optical isomers such as sugars, amino acids, and proteins. The Go Direct Polarimeter is simple to use, includes free, downloadable experiments, and is supported by the free Vernier Instrumental Analysis™ app.

The Polarimeter can be used to measure chiral properties of optically active samples without chemically modifying or destroying the sample. This is a vertical polarimeter that uses a 589 nm LED, a fixed polarizer, and a manually rotated polarizer to detect changes in rotation of plane-polarized light in the presence of an optically active compound. Used with Vernier technology, students no longer have to determine the optical maximum with their eye but have a graph that shows a clear change in the light's polarization.
