665 647
Gas generator after MAEY
Used to prepare gases from solids (granulates)
and liquids. The MAEY-type gas generator is
economical, requires only small amounts of
substances and is easy to clean.
In addition, it is universal in its application
(e. g. with dropper funnel > 665 649).
- Hydrogen: H 2 from Zn and HCl
- Carbon dioxide: CO 2 from CaCO 3 and HCl
- Nitrogen oxides: NO x from Cu and HNO 3
- Hydrogen sulfide: H 2 S from FeS and HCl
- Sulfur dioxide: SO 2 from Cu and H 2 SO 4

Dropper funnel
With pressure equalization, 75 ml , ST stopper
and 2 ST 29/32 fittings, with stopper. The ideal
accessory for the MAEY-type gas generator.
Combining these two units makes it possible to
also produce gases from mixtures of liquids
or powders with liquids:
- Oxygen: O 2 from MnO 2 and H 2 O 2
- Chlorine: Cl 2 from KMnO 4 and HCl
- Hydrogen chloride:
HCl from NaCl and H 2 SO 4
- Ammonia gas:
NH 3 from NaOH and NH 3 solution
- Carbon monoxide:
CO from H 2 SO 4 and HCOOH
- Acethylene:
Acethylen (Ethin): C 2 H 2 from CaC 2 and H 2 O
- Methane: CH 4 from Al 4 C 3 and H 2 O
