 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.
