Reducing adhesive and solvent waste by proper labelling

It may be a familiar sight to many of us: a cabinet full of half-used bottles of Paraloid in solutions of various concentration. Yet, due to incomplete labelling you cannot be sure it is what you need.

Adhesive and solvent waste in shared lab space can be reduced by clear labelling with:

- Chemical hazard labels

- Adhesive

- Solvent

- Concentration (w:w, v:v or w:v %)

- Date

- Marking the level

Marking the level of the adhesive in solution with a permanent marker will help your colleagues to see and re-fill any evaporated solvent approximately to the original concentration. After each use of the adhesive-solvent mixture the mark needs to be re-applied.

Note: The rejuvenated adhesive can be used but it may yellow slightly.
