The Set :
You
can select :
-
A
100x50mm pair of 1xMMO in plate + 1Cathode plate
- An
simple mesh Anode of 150x60mm as draw+pictures
Specification
:
-
Anode : MMO made of Ru-Ir coating on Titanium substrate provides
excellent resistance to chemicals, and oxidation.
-
Electrodes
size (as
the pictures):
- 100x50x1mm
of plate working surface + thread connectors,
- 200x60x1,2mm
of
working surface + thread
connectors
-
Cathode : pure titanium plate, same size, Grade 1.
-
The lifetime is very high, but depends on the use conditions (15 000
hours in swiming pool)
- Max current is 200mA/Cm2 for chlorate,
less for hypochlorite.
- The
coating is 12g/m² 50/50 Ir/Ru for the 200x60mm model and 8g/m²
30/70 Ir/Ru for the 100x50mm model (this
point impact the prices).
-
Max working temperature: near
70~80°C
(higher temperature = slightly shorter lifetime but better yield for
chlorate. Hypochlorite must stay under 40°C)
- This anode allow
to electrolyze from chloride to chlorate in one step.
- The lid
is 120x120x2mm in white PVC (more resistant to chlorine gas than PMMA
old version).
- Durable and reliable laboratory equipment.
-
This coating is reliable and is enable to reach 75 % of yield at
65°C during thousands of hours without visible degradation. (with 3
or 4g of persulfate/liter).

Warning:
-
Put the « + » wire on the Anode (the dark one) and the
« – » on the 1 or 2 Cathodes.
- Ru-Ir coating is
quite sensitive : never chock or strike them.
- Avoid fluorine
and all fluorine salt (persulfate works very well).
- Respect
the max current to avoid fast degradation.
- Don’t reverse
polarity, it will rapidly destroyed the electrodes.
- Gas are
dangerous and flammable, the running cell MUST work in appropriate
place.
- Read the manual.
- In some countries, for
non-laboratories, some chlorate and their concentrations are
restricted.
- It is
strongly advised to “brush” the threaded parts of the connectors
with a metallic brush : steel or brass bristles (welding brush works
very well), with protection arround the lower part of the
connector.
This operation is very important if the temperature
seems to rise on the connector, with a gradient above +20°C from the
brine’s temperature.
- On some
older anode models, the connector is covered with a black coating
(which resists corrosion) but it is also a poor electrical
conductor.
It is recommended to brush this coating, although 95%
of my clients have not noticed any particular problems by keeping it.
Package included:
- The
selected pair of MMO (200x60 in mesh or 100x50 in plate) + cathode +
2 PTFE washers
