Our precision cells are manufactured from glass and quartz and possess all the advantages and disadvantages of this material. We generally recommend to clean and dry the cells immediately after use and to return them to their storage case. Do not keep the cells in the open in a corrosive atmosphere and do not leave the polished windows in contact with liquid over long periods of time. Both conditions could lead to formation of deposits or stains and could render the cells useless. To avoid scratches on the precision-polished windows, the cells should never come into contact with objects made of hard materials such as glass or metal.
Care is required when inserting cells into a metal cell holder.
When filling the cells with liquids using a pipette, never touch the polished windows with the pipette. Never use metal tweezers or pliers for carrying or holding the cells. Cleaning of Cells Quartz as well as the other optical glasses used for our cells are highly resistant to chemicals. This means that with a few exceptions all alkaline and acidic solvents, including organic solvents, may be used for cleaning. We recommend that if you know the nature of the contaminating substance, for cleaning use the solvent in which the substance was dissolved.
