More important, it will waste your time! Also inspect the condition of the cells. If they are cracked, chipped or scratched it is important to replace the cells with new ones as your time is more valuable than the cost of new cells.

| N.B: For Fluorescence measurements - Clean and store cells in Nitric Acid (5M) use a copious water rinse immediately Before use General Considerations:- Keeping cell clean while in use is the most important element of a long, useful Cell life. During the day, never let your cells dry out. If your keep them in a water or solvent bath between usage, the material that you are using will not have a chance to dry out and stick. Use only lens cleaning paper or fine cloth to wipe the optical surfaces, most paper products contain wood fibres which may scratch or damage the cell face or surface. At the end of the day, ensure all cells are well cleaned and store in a suitable container after drying. |

| N.B: 5M Nitric acid: Do not use this treatment on Anti-reflection or mirror coated cell's Ultrasonic Cleaners: We do not recommend the use of ultrasonic cleaning baths with cells. Each bath generates a different frequency and if your bath operates at the resonant frequency of a cell, the cell will break. We do not warranty that our cells for cleaning in an ultrasonic cleaner. |
