Multi-parametric biosensor for glucose, lactate, glutamine & glutamate

Multi-parametric measurements

The IST AG LV5 sensor is a flow-through biosensor and offers multi-parametric measurements. Up to 4 analytes can be measured simultaneously (glucose, lactate, glutamine, glutamate). The sensor features a very small flow cell (1 µL) and therefore requires minimal sample volumes when used as an analyzer.

Further advantages of the LV5 biosensor include:

  • Excellent long-term stability over a month in continuous measurement mode (lifetime varies depending on various factors, including the analyte concentration and buffer system (medium) amongst others)
  • Long shelf life (under appropriate environmental conditions) 
  • Gamma and beta sterilization compatible
  • Suitable for continuous and analyzer measurement modes
  • Fast response time (depends on the buffer system (medium))
  • Reference, counter and blank electrodes on-chip
  • Integrated flow cell (various volumes)

The LV5 biosensor is suitable for sampling systems in laboratories or food and pharmaceutical industries.

IV4 Biosensor for single parametric dip-in measurement

IV4 - Optimal for stable continuous single parameter dip-in applications

The IST AG IV4 biosensor is a flexible stripe with large form factor ideal for direct dipping in the measurement media. It is designed for the detection of a single analyte, glucose as standard. This sensor is ideal for applications that require in-line continuous measurement with high reliability.

Further advantages of the IV4 biosensor include:

  • Excellent long-term stability
  • Long shelf life
  • Gamma and beta sterilization compatible
  • Fast response time and outstanding reliability
  • Reference, counter and blank electrodes on-chip

Given its compatibility with gamma radiation, the IV4 sensor can be used for example in bioreactors or aseptic media.

SIX Biosensor Transmitter - Evaluation Kit for Amperometric Biosensors

The SIX Biosensor Transmitter enables a direct evaluation of LV5 and IV4 biosensors. It can be directly connected to a computer via USB or to any microprocessor via a standard TTL-serial interface. The evaluation software bioMON is also available for the acquisition of measurement data and its analysis in real time.

Further advantages of the SIXBiosensor Transmitter:

  • USB connectivity for easy evaluation
  • OEM version with serial interface for easy integration in custom developments
  • Very high current precision (approx. 20 pA)
  • 6 current channels with common reference and counter terminals
  • Current range can be factory-adjusted to meet specific requirements
  • Very light weight
  • Evaluation software bioMON available
