Oxygen Measurement Overview

Hansatech Instruments Ltd Oxygen Electrode Measurement Systems are based around the S1 Clark type oxygen electrode disc. The oxygen electrode systems featured on this website are configured to allow studies within a wide range of applications in cellular respiration and photosynthesis research. The systems are divided into 2 categories.

  • Liquid-phase
    Oxygen electrode systems are available for the measurement of oxygen evolution or uptake from chloroplasts and other suspended plant photosynthetic materials (micro-algae etc.) and oxygen consumption by various components including plant roots or various plant or animal cell suspensions including mitochondria respiration studies. These may be effectively monitored using different combinations of modular items that together form compact, user-friendly systems for research applications or teaching.
  • Gas-phase
    Gas-phase oxygen electrode systems allow the measurement of oxygen evolution or uptake within a sealed sample chamber. The sample chamber is designed to accommodate 10cm2 leaf discs which are cut using a special leaf disc cutter. However, any sample type such as root sections, lichens, mosses, conifer needles or small seeds may be used.

To learn more about these systems and to determine which instrument best suits your application, please get in contact with PP Systems to speak to a products specialist.  We look forward to being of assistance.

OxyTherm from Hansatech Instruments

Oxytherm

Oxytherm provides the convenience of the Oxygraph system for the study of respiration by oxygen uptake in liquid suspensions of 200µl – 2.5ml. It additionally features precise solid-state temperature control (+3 to 40 degrees C) without need for a circulating water supply. The electrode unit has an integral small diameter oxygen electrode disc, sample illumination facility and fibre-optic port to suit 8mm diameter fibre-optics such as those from the FMS2 chlorophyll fluorimeters. Windows® software supplied for system/ temperature control and data analysis.
