Flask-Cap Biosensor for Glucose and/or Lactate

Monitor glucose and/or lactate concentrations in any type of flask for up to 21 days without interruption. CITSens Flask-cap sensors are supplied pre-sterilized with a built-in sensor. Unique electronics and innovative enzyme stabilization technology make this the best choice for accurate, long-term monitoring. Calibration is automatic once the sensor is paired with the accompanying control software via a compact data transmitter. Simply let us know the manufacturer and cat.# of your flasks when requesting a quote.

CITSens Flask-Cap Biosensors


  • Eliminates tedious and risk-prone manual sampling
  • Provides convenient long term remote monitoring and data recording
  • Reduces the risk of contamination and culture perturbation

Unlike other biochemical sensors these biosensors are designed so that every electron obtained from the enzyme-substrate reaction will contribute directly to the measurement of concentration. This means greater accuracy. It also means that H202 generation is avoided and that undesirable oxidized media components will not accumulate.

Flow Cell, Flask or Reactor Probe Designs

A range of single-use sensor designs is available: 1) flow-through 2) flask-cap 3) reactor probe. Sensors connect remotely via a compact transmitter to the associated data-recording and control software that is provided ready-installed on an industrial mini-PC or tablet. Each system is designed to be “plug-and-play”. The choice of hardware option depends on type of sensor.
