The Abbe 5, manufactured by Bellingham and Stanley, is a cost-efficient refractometer which is generally designed for applications requiring a wide refractive index measurement. In relation, these mentioned applications typically involve small contract laboratories or procedures wherein the sample throughput is relatively low.
This refractometer is also suitable for practical demonstrations as well as experiments related to chemistry and physics of academically-inclined laboratories. With that, this device is the best complement to the newly-released optical polarimeter (model: D7).
