Can I make GelRed®/GelGreen® gels ahead of time and store them for later use?

Ask a question

You can store precast GelRed® gels for up to a week, and GelGreen® gels for up to a month. We recommend storing gels at room temperature in the dark. We no longer recommend storing gels at 4°C, because this can lead to dye precipitation and poor performance.
