InLab® Glossary

Type of membrane glass

• A41 glass

  Particularly resistant to chemicals; suitable for high temperatures up to 130 °C; ideal for biological media.

• HA glass

  High alkali glass for use at high pH values and high temperatures; extremely low alkali errors; extremely robust membrane.

• HF glass

  Especially suitable for media containing hydrofluoric acid; up to a HF concentration of 1 g/L.

• LoT glass

  Low resistance glass for use at low temperatures (LoT = low temperature); also suitable for low ion concentrations (ultra-pure water); the glass of choice for thick membranes (puncture or surface electrodes).

• U glass

  Universal glass, tried and tested in standard applications; especially suitable for small membranes (microelectrodes).

Type of junction

• Click & Clear™

  Thanks to the press mechanism, the sleeve junction is easy to open with combined perfectION™ ISE; quick cleaning and stable measurement values are ensured even in difficult samples.

• Movable glass or PTFE sleeve

  Movable sleeve junctions that can be easily and thoroughly cleaned.

• Immovable glass sleeve

  Fixed sleeve junctions for large contact area between reference electrolyte and measurement solution.

• Ceramic

  Conventional ceramic junctions for liquid electrolytes or in combination with SteadyForce™.

• Ceramic ring

  Large ring-shaped ceramic junctions for flat membranes.

• Open junction

  Open connections without junctions together with XEROLYT ® polymer electrolyte.

• Porous PTFE

  Large contact surface polytetrafluoroethylene (PTFE) junctions.

Technologies, reference systems and reference electrolytes

• ARGENTHAL™

  AgCl granulate-filled cartridge, which supplies the silver ions for the chemical reaction on the conducting wire. The silver ion trap stops the Ag+ ions from discharging into the electrolyte solution, thus preventing contamination of the junction when using sulfides and proteins.

• DPA-Gel

  Gel electrolyte for electrodes with SteadyForce™.

• driTEK

  Reference system for ISFET electrodes.

• Equithal ®

  Reference system for ISFET electrodes.

• FRISCOLYT™

  Symmetrically structured conducting elements guarantee minimum response times and highly stable potentials when fluctuating temperatures are involved.

• ISM ® (Intelligent Sensor Management)

  In sensors with ISM ® , important information, such as calibration data, is stored on a chip directly in the sensor and automatically detected by the meter. Only with SevenExcellence™, SevenCompact™ and SevenGo Duo™ meters.

• SteadyForce™

  Reference system in which the electrolyte is pressurized (3 bar) to ensure discharge of electrolyte even in viscous samples.

• XEROLYT ®

  Solid polymer electrolyte in combination with open connections.

Shaft materials

• Stainless steel

  316L (V4A) grade stainless steel.

• Epoxy

  Very strong plastic with excellent chemical and mechanical resistance. For very robust sensors.

• PEEK

  Polyetheretherketone: Highly temperature-resistant plastic with excellent chemical and mechanical resistance. For professional and heavy-duty sensors.

• Polysulfone

  Plastic with good chemical and mechanical resistance.

• PPS

  Polyphenylene sulfide: Partly crystalline, highly temperature-resistant plastic with excellent chemical and mechanical resistance. For robust dissolved oxygen sensors.
