Kushandiswa

Polyvinylpyrrolidone inoshandiswa zvakanyanya mukurapa uye ndeimwe yemishonga mitatu mitsva inokurudzirwa pasi rese. Zvinonamira zvinonyanya kushandiswa mapiritsi nemagranules. Inogona zvakare kushandiswa senzira yekubatsira pakuyerera kwemakapisi, kubvisa tsvina mumuviri uye mafuta ekurapa maziso, chinhu chinonyungudutsa mujekiseni, chinonyungudutsa mukugadzirwa kwemvura, uye chinosimbisa ma enzyme nemishonga inonzwa kupisa. Povidone inogona zvakare kugadzirwa ne iodine povidone iodine (PVP-I) disinfectant. Muma lenzi ekuonana, PVP inoshandiswa sechikamu chema lenzi ekuonana kuti iwedzere hydrophilicity yavo. PVP inogona zvakare kushandiswa se cryogenic preservative mukurapa.
