Products
Microcathode Oxygen Electrode (SI1302)
Clark-type polarographic microcathode oxygen electrode with platinum cathode and silver/silver chloride anode, compatible with PP or FEP membranes and designed for low oxygen consumption and stable output.
Dual Channel Oxygen Meter (SI782)
Oxygen meter that operates with one or two oxygen electrodes; can function stand-alone or connect to PC software for recording and automatic respiration rate calculations.
Six-Channel Oxygen Meter (SI928)
Multi-channel oxygen meter capable of operating up to six microcathode electrodes simultaneously for parallel dissolved oxygen and respiration measurements.
Multi-Cell Respirometer (RC650)
Six-cell respirometer for replicate small-volume respiration measurements (1–3 mL) with integrated magnetic stirring and compatibility with multi-channel oxygen meters.
Respiration Cell (RC300 / RC350)
Water-jacketed respiration cells for small-volume oxygen uptake measurements with adjustable sample volumes (RC300: 0.3–1.0 mL; RC350: 1.0–3.0 mL) and parking chamber for electrode thermal stability.
Mitocell Respirometer (MT200 / MT200A)
Micro-volume respirometer system for mitochondrial and cell preparations with interchangeable glass chambers for volumes from 50 µL to 1 mL and automatic calculation of respiration parameters when used with compatible meters/software.
