Capillary and Temperature Sensor
Capillaries from PEEK are used to make the bubbles. PEEK can withstand
temperatures and is resistant to highly concentrated alkaline solutions as well
as non-oxidising acids. The resistance against solvents is excellent, too.
PEEK is highly hydrolysis resistant to boiling water.
In order to quickly change the capillaries, they come with a Luer Lock
connector. For attaching the capillary to the sensor head simply plug it onto
the Luer connector and turn to the right. Please, keep the inner seal clean in
order to guaranty a sealed system.
Note that the PEEK capillaries are not resistant against
concentrated sulphuric acid and oxidising chemicals such
as concentrated nitric acid and wet chlorine gas.
Do not immerse the complete capillary into the
ultrasonic cleaning bath and/or any solvent!
For cleaning the capillary refer to chapter 12.4!
The temperature sensor (Pt 100) is from stainless steel
and should be resistant to most chemicals. For critical
cases or if you have doubts, you are asked to use a
protective sheath from PTFE which the manufacturer can
supply on demand.
