EC/pH Precision Control for Plant Tissue Culture

Nutrient delivery at laboratory precision: ±0.05 pH, ±0.1 mS/cm EC. Phase-specific profiles for multiplication, rooting, and hardening.

Why EC/pH Drift Destroys Tissue Culture Batches

Plant tissue culture media must maintain exact electrical conductivity and pH for each growth phase. Manual mixing and periodic sampling creates drift — by the time you catch a deviation, the batch is already stressed.

Multiplication Phase: NH4/NO3 Balance

Shoot multiplication requires precise ammonium-to-nitrate ratios. EC drift of ±0.2 mS/cm above target reduces shoot count by 15-20%. Automated dosing maintains the setpoint within ±0.1 mS/cm across the entire batch cycle.

Rooting Phase: pH-Dependent Auxin Uptake

IAA and IBA auxin availability drops sharply when media pH exceeds 5.8. A 0.3 pH deviation during the first 7 days of rooting reduces root initiation by up to 40%. Continuous pH monitoring with ±0.05 accuracy eliminates this variable.

Hardening Phase: Gradual EC Transition

Transition from in-vitro to ex-vitro conditions requires a controlled reduction in media osmotic potential. Manual step changes shock the plantlets. Automated EC ramping over 5-7 days increases survival rates from 70% to 90%+.
