Although non-contact (e.g. ultrasonic) cleaning is essential for final critical cleaning processes, mechanical cleaning methods such as sponge and brush cleaning may be more efficient for removal of “macro” contamination, or very tenacious contaminants like waxes and polishing compound.

Unfortunately, mechanical cleaning processes are typically performed manually, and tend to be both time consuming and inconsistent. Moreover, they can put operators at risk of repetitive stress injury.

Interlab’s newest ophthalmic product is an automated brush-washing system that can thoroughly scrub up to 8 lenses/minute. Brushes gently clean BOTH SIDES of each lens, thoroughly preparing it for final cleaning, and subsequent dip or u/v coating. The washing stage of the system uses a mild detergent that is filtered and recirculated for longer life, then automatically rinses and blows lenses virtually dry. The rotary configuration allows the unit to be compact, while performing as an “in-line” processor. A single-sided version is also available for lenses that must be cleaned on only one side.
