Caution
Strong acids and prolonged heating may cause the agar molecules to break down into oligosaccharides and lose their physical properties.
For the preparation of plant media with high water retention requirements and for bacteria culture media with multiple suspension spreading or bumpy incubation/storage conditions, we recommend the use of
Premium grade agar strength ~1400 g/cm2, 137KPa
Carrageenan strength ~1400 g/cm2, 137KPa (FOR Plant culturing only)
Gellan gel (Phytagel) strength ~1700 g/cm2, 166KPa
1~2% gellan & pullulan composite hydrogel strength 2000~2500 g/cm2, 198~245KPa
