Product description

Physan 20 15ml bottle. Physan 20 is used when cleaning tissue cultures during deflasking. The baseline to know: the standard general-purpose rate is about 1 teaspoon per gallon, and 1 teaspoon ≈ 80–90 drops, so the numbers below scale from there. Tool & surface sanitizing (blades, scissors, pots, trays, benches — general rate) 1 cup water → 5–6 drops 1 quart → 20–22 drops 1 gallon → about 1 tsp (80–90 drops) Wipe or dip, let it sit wet a minute or two, then use. Great between every cut so you're not spreading anything plant to plant. Incoming-plant general plant soak (algae, mold, surface fungalbacterial on established plants) 1 quart → 20–22 drops 1 gallon → ~1 tsp Dip or spray, don't leave established roots soaking long. Deflasking tissue-culture soak — go gentler here, TC plantlets are fragile and have no cuticledefenses yet Use a weak rate: roughly 1 quart water → 8–10 drops (about half the normal strength, ~½ tsp per gallon) Quick dipswish only — 30 seconds to a couple minutes, just to knock back agar residue and contamination, then rinse in clean water before potting into your sterile mix. The goal at deflasking is gentle decontamination, not a hard sterilize — too strong will burn those tender plantlets faster than anything.
