The biggest threats to the quality of your goods are exposure to the air, water and sunlight.

All our goods are supplied in air tight, amber containers with secure taped necks. When you get your goods you should refrigerate them or re-freeze for longer storage periods.

Always minimise the reagents exposure to the air and water. Practically this means using the reagent as soon as it leaves the bottle,  not storing it in solution, not leaving the bottle tops off and taping the tops back on after use (with electrical tape or something similar). Your goods should not be stored where they will be exposed to light.

Having said that the reagent is relatively stable for short periods so you can calmly and carefully handle your sample in your lab without any quality degradation!
