The OxyProbe 12 mm autoclavable dissolved oxygen sensor offers the most rugged and versatile design for benchtop bioreactor vessels. The compact profile saves space on a crowded headplate. It will fit directly into any 12 mm multipurpose port with standard compression fittings or Pg13.5 threads. The small diameter facilitates DO measurement in small volumes, especially bottles and spinner flasks.

The OxyProbe 12 mm autoclavable Dissolved Oxygen sensor has the same rugged performance as the 19 mm and 25 mm sensors. This polarographic sensor utilises the longer silver anode and small cathode which has become the industry standard. It also uses the same semi-permeable, Silicon/Teflon composite membrane, reinforced with stainless steel mesh.

All OxyProbe dissolved oxygen sensors are also available with a right angle connector. This low profile design provides:

  • Protection against cable fatigue
  • Improved grip for sensor extraction
  • Increased clearance between vessels
  • Reduced random sensor mobility on flat surfaces (won’t roll off the table)

D140 (12mm) Autoclavable Dissolved Oxygen Sensor Specification

  • 316L Stainless Steel
  • Serialised for traceability
  • RA32 finish with electropolish on wetted parts
  • Internal EPDM o-rings
  • Membrane cartridge kits available (see Accessories tab for compatible kits)

Membrane Kits

Broadley-James offer a range of membrane kits to suit all our dissolved oxygen sensors. These include everything required to replace the membrane cartridge and internal o-rings. All kits include:

  • QC Certificate
  • Material Cert

The following membrane kits are suitable for use with the D140 Autoclavable DO Sensor:

Membrane Kit Example Image Kit Contents
Single cartridge kit for 12mm DO Sensors

Part No. KC1201

DO sensor 12mm single membrane kit One 25 ml bottle of electrolyte

One membrane cartridge

One set of internal o-rings

Four cartridge kit for 12mm DO Sensors

Part No. KC1204

DO sensor 12mm 4 membrane kit One 25 ml bottle of electrolyte

Four membrane cartridge

Four set of internal o-rings

25 Piece cartridge kit for 12mm DO Sensors

Part No. KC1225

DO sensor 12mm 25 membrane pack 25 membrane cartridges in one easy-to-store box.

Internal o-rings, gaskets and electrolyte must be ordered separately.

Compatible Cables

The D140 Autoclavable DO Sensor uses a D4 connector. This industry standard connector was the first, and is still, the best choice for DO sensors. We recommend the following cables for use with the D140 Autoclavable Dissolved Oxygen sensor:

Cable Type Sensor connector & Device Connector Device Terminal
D4 plug to Lemo 6 lemo6-d lemo6
DO Cable D4 to Crimped Ferrules crimp-d terminal-block

How to choose a sensor

It is important to regularly maintain the sensors by inspecting and calibrating them. The membrane cartridge should be checked and refilled prior to every use.

The internal seals of an Oxyprobe are all mechanical seals using o-rings. There are no adhesives to leak or fail in process, making this a more rugged and reliable sensor. Replacing the cathode is also much easier and faster since there is no sealant to clean from the threads. No sealant also makes the job of replacing the cathode much faster and cleaner.
