Contact Lens Refractometer J457CLR
Manufacturer: Rudolph Research Analytical
SKU: Refractometer J457CLR
Description
The J457CLR from Rudolph Research Analytical is a benchtop digital refractometer tailored for the ophthalmic and contact lens industry. Its primary function is the accurate determination of the refractive index for both rigid and soft contact lens materials, as well as for testing the concentration of associated saline and cleaning solutions. The instrument provides a wide refractive index measurement span from 1.26 to 1.72, with a precise resolution of ±0.00001 RI. It operates within a temperature range of 10°C to 110°C and supports additional measurement scales including Brix percentage and urine specific gravity. This capability makes it a versatile tool for quality assurance in manufacturing processes and for verifying the specifications of lens-care products.
