Bellingham And Stanley Launch New High Precision, Touchscreen Peltier Temperature Controlled Refractometer

Both features are ideally suited for use in applications within the chemical, petrochemical, pharmaceutical, flavours and fragrance industries as well as in academic research.

Bellingham + Stanley has been manufacturing refractometers for over a century and the latest refractometers build on that legacy. The instrument’s new case is ergonomically designed so that any spills are dealt with by the sloping shape of the case or by the PEEK spill barrier that surrounds the shallow, easy-clean stainless steel prism dish. The prism dish is shaped to hold sufficient sample for measurement whilst regaining a large enough surface area for rapid temperature stabilisation to occur.

A Kalrez® gasket has been chosen as the prism seal due to its almost impermeable nature to most chemicals. The sample cover forms a seal to prevent evaporation, particularly important when working with volatile solutions such as aromatic oils, and is interchangeable so that a presser type can be fitted for more viscous samples.

Inherent to the new design is the new high definition, capacitive touch-screen display that not only facilities operation in factory environments, even when operated whilst wearing certain types of protective gloves, but also serves as the centrepiece for the new software. Combined, the touchscreen and GUI help the operator quickly manoeuvre through the user and configuration menus.

On-screen graphical prompts support simple operation such as method loading, calibration and routine maintenance.
