Product Information

For measurement of gas permeable and soft (hydrophilic) contact lenses. Working with a leading manufacturer of contact lenses, Index Instruments have developed the CLR 12-70 fully automatic refractometer. This instrument will allow you to measure refractive index, water, or solids content of gas permeable and soft contact lenses. The CLR 12-70 measures clear or colored iris lenses with equal ease and accuracy. It also has built-in user programmable, water content scales for up to 10 different polymer materials. Gone are the problems of slow, inaccurate, manual refractometers. With the CLR 12-70, you can measure up to 60 samples in an hour with ease. The instrument has been designed for use by even unskilled staff and allows you to move quality control out of the laboratory and into production area.
