Bellingham + Stanley OPTi Digital Range Refractometer – Life Science

Refractometers play small but vital role within the life science sector for both human and veterinary use. Whether the need is to control the sugar content of sports drinks prior to consumption or to track hydration levels of our athletes taking part in a sporting event, the duo scale OPTi-Sport is the right for the job. Similarly in the veterinary field, the OPTi-Vet is used to ascertain sugar levels of animal urine, large and small, as part of a diagnostic procedure.

The OPTi-Aquarium also has two scales expressing seawater concentration in either parts per thousand (PPT) or specific gravity (SG) and is not only used as a means to test the salt content of fish tanks at home or within the fish farming industry (aquaculture) but also in our shipping industries, where seawater is used as an engine coolant, and as an environmental tool to track the stability and degradation of our rare wetlands and salt plains.

The OPTi also plays an important part in horse and rare animal breeding too, where the instrument is used to monitor mares milk colostrum quality to ensure the correct levels of immunoglobin is being delivered during those first few days of life!
