  10. PENGUKURANpH • PengukuranpH dalambioreaktor • Secara kualitatif • Secara kuantitatif VIDEO

  11. Metode Pengukuran pH • pH meter • Litmus Paper

  12. pH Meter Bilas probe dengan air sebelum memasukkannya ke dalam samppel Siapkan sampel yang akan diukur Kalibrasi alat (pH 7 & pH 10) Masukkan probe dalam sample, tunggu hingga hasil seimbang Catat hasil

  13. Litmus paper Celupkan kertas lakmus ke dalam sample selama 3s Lihat perubahan warna pada kertas lakmus Cocokkan dengan tabel warna yang ada dalam kemasan

  14. KALIBRASI • Siapkanalat pH-meter besertaelektrodedanlarutan buffer • Nyalakanalatdanpilih mode kalibrasi • Bilaselektrodedenganaquadestdancelupkandalamlarutan buffer yang pertama (pH buffer 4) • Catat slope danbandingkandengan range slope pada manual alat, pH meter dapatdigunakanbilaberadadalam range yang terdapatpada manual alat • Bilaselektrodedenganaquadestdancelupkandalamlarutan buffer yang ketiga (pH buffer 10) • Bilaselektrodedenganaquadestdancelupkandalamlarutan buffer yang kedua (pH buffer 7) VIDEO
