Freezers hold some of the most valuable materials in a research lab, yet they are often managed by habit rather than by plan. A few simple practices protect your samples.

Temperature

Lyophilized peptides are usually stored at -20 C or colder. Keep a temperature log and add an alarm to any unit holding critical stock.

Avoid frost-free units

Frost-free freezers warm up briefly during defrost cycles. Those swings stress sensitive samples over time.

Light and moisture

• Store vials in opaque boxes
• Add desiccant packs to reduce moisture
• Let vials warm to room temperature before opening to prevent condensation

Aliquot early

Repeated freeze-thaw cycles degrade peptides. Divide reconstituted material into single-use aliquots.

Map your freezer

A simple shelf map, updated whenever stock moves, saves time and prevents doors being left open while you search.

Some compounds, such as the small molecule SLU-PP-332 10mg, have their own storage needs, so check the guidance for each product. A supplier of research peptides online that publishes clear storage information makes planning easier.
