DP-PSt6-L2.5-St10-YO

DP-PSt6-L2.5-St10-YO

Oxygen Dipping Probe DP-PSt6

  • Measurement range of 0 - 5 % O2 with 1 ppb detection limit
  • Excellent long-term stability
  • Pressure resistant (max. 5 bar)
  • Polarization-free
  • No membrane clenaing and replacement necessary
  • No electrolyte solution to replenish
  • Long shelf life

The oxygen probe DP-PSt6 for measurement in trace oxygen range basically consists of a polymer optical fiber with an oxygen-sensitive sensor foil attached to one end. It has a measurement range of 0 - 5 % oxygen with a detection limit of 1 ppb.  This end of the fiber is covered in a high grade steel tube to protect both the sensor material and the fiber. The steel tube has an outer diameter of 4 mm and a length of 10 cm. Other lengths are available on request. Due to the use of a polymer optical fiber this probe is compatible to temperatures up to + 70 °C

Specification

DP: Dipping Probe
PSt6: trace oxygen sensitive coating 0 - 5 % oxygen
L2.5: length of optical fiber is 2.5 meter
St10: length of steel tube is 10 cm
YOP: with additional optical isolation

FTC-PSt6-L2.5

Autoclavable O2 Flow-Through Cell FTC-PSt6-YAU

  • Online oxygen measurements in perfusion systems
  • No consumption of oxygen
  • Signal independent of flow velocity
  • Autoclavable

The FTC-PSt6-YAU is a miniaturized trace oxygen sensor integrated in a flow-through cell. A glass tube with an inner diameter of 2 mm is coated with the sensor at its inner wall. The FTC is connected to the oxygen meter with an optical fiber. The volume for liquid inside the FTC is about 100 microliter. The standard flow-through cell can be easily connected via Luer-Lock adapters to external tubings.

Specification

FTC: flow through cell with integrated planar oxygen sensor
PSt6: oxygen sensitive coating 0 - 5 % oxygen
L2.5: length of optical fiber is 2.5 meter

OIM-PSt6-D12/L120-L2.5

OIM-PSt6-D12/L120-L2.5

Oxygen Probe for In-Line Measurement OIM-PSt6

  • Stands autoclaving, SIP (+ 130 °C, 1.5 atm) & CIP (2 % NaOH, + 80 °C)
  • Polarization-free
  • No membrane cleaning and replacement necessary
  • No electrolyte solutions to replenish
  • Pressure resistant
  • Measurement in steel fermenters
  • Trace oxygen measurements in brewing and beverage industries

The OIM-PSt6 has a stainless steel fitting with standardized length and thread, so it is compatible with most bioreactors and port adapters. The optical trace oxygen sensor has a measurement range of 0 - 5 % oxygen and a detection limit of 1 ppb. It is integrated in an Optical Exchange Window, which is screwed to the top of the metal fitting and can be replaced if needed. The probe has excellent long-term stability and can be equipped with a customized fitting for e. g. sight glasses.

Specification

OIM: oxygen probe for inline measurement in fermenter
PSt6: sensor coating type PSt6 0 - 5 % oxygen
D12/L120: steel tube diameter 12 mm / length 120 mm thread PG13.5
L2.5: length of optical fiber is 2.5 meter

SP-PSt6-NAU-D5-YOP

SP-PSt6-NAU-D5-YOP

Oxygen Sensor Spot SP-PSt6-NAU (Minimum Order Quantity: 10)

  • Non-invasive measurements through the vessel wall
  • No consumption of oxygen
  • Signal independent of flow velocity
  • Measures oxygen in liquids as well as in gas phase

Sensor spots are the most versatile version of non-invasive optical oxygen sensors. They can be attached to the inner surface of any transparent glass or plastic vessel like e. g. used for packaging. Oxygen is measured contactless through the transparent vessel wall. The SP-PSt6-NAU has a measurement range of 0 – 5 % oxygen, dissolved or in the gas phase. The oxygen sensitive coating is immobilized on a 125 µm flexible transparent polyester foil, which does not stand autoclaving..

Specification

SP: planar sensor spot
PSt6: oxygen sensitive coating 0 - 5 % oxygen 
NAU: stands CIP but does not stand autoclavation, 
immobilized on 125 µm flexible transparent polyester foil
D5: spot diameter is 5 mm
YOP: with additional optical isolation

SP-PSt6-YAU-D5-YOP

Oxygen Sensor Spot SP-PSt6-YAU (Minimum Order Quantity: 5)

  • Non-invasive measurements in a range of 0 - 5 % oxygen
  • No consumption of oxygen
  • Signal independent of flow velocity
  • Measures oxygen in liquids as well as in gas phase
  • Autoclavable

These sensor spots are the most versatile version of optical trace oxygen sensors. They can be attached to the inner surface of any transparent glass or plastic vessel like e. g. used for packaging. Oxygen is measured contactless and non-destructively through the transparent vessel wall. The SP-PSt6-YAU has a measurement range of 0 – 5 % oxygen in dissolved or gaseous phase. The oxygen sensitive coating is immobilized on a 1 mm glass support, which can be autoclaved.

Specification
