Sera Dest is a rinsing solution for electrodes. Before dipping electrodes from one solution into another, they should be thoroughly rinsed with Sera Dest in order to avoid contamination by transferring solution remainders via the electrode tip. The rinsing water must be thrown away and never reused. Test solutions may be ruined after just ONE contamination.
Use with Sera Nitrate and Sera Phosphate Test Kits so that the exact determination of these elements can be established.
