Txoj Kev 1 ntawm 5: Kev Npaj Ua Ntej Lyophilization
Kauj Ruam 1. Xaiv hom khoom noj uas koj xav khaws cia
Cov zaub mov uas muaj dej ntau yog qhov tsim nyog rau kev khaws cia los ntawm lyophilization. Tus qauv thiab kev ntxhib los mos ntawm cov txiv hmab txiv ntoo yuav nyob tsis tu tom qab dhau los ntawm cov txheej txheem no. Nov yog qee qhov piv txwv ntawm cov zaub mov uas tsim nyog rau kev khaws cia los ntawm cov txheej txheem no:
