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 ® Symmetrically structured conducting elements guarantee minimum response times and highly stable potentials when fluctuating temperatures are involved.
FRISCOLYT™ Special electrolyte for measurements at low temperatures and for media with organic components (e.g. oil, proteins, etc.). Recommended for storage of electrodes with XEROLYT™.
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
