Euthanasia Unit

UNO developed the euthanasia unit based on the present views on euthanasia in rats and mice.
As described in the articles published in the Laboratory Animal (1995 - volume 29) and Laboratory
Animal Science (August 97 , volume 47 number 4), euthanasia through a mixure of O2 and CO2
is prefered over euthanasia through CO2 only. This conclusion is based on behaviour studies,
EEG and ECG performed during the euthanasia in rats.
(Articles on request available!) The UNO Euthanasia Unit uses PLC pre-set programs.
The main advantage hereoff is that the procedures for euthanasia can be easily described
in a protocol for the users of the unit. (The PLC controlled programs can be altered by UNO).

The UNO Euthanasia unit consists of:

A polycarbonate box with lid, in which the mouse and rat cages can be placed.
Dimensions: 50 x 75 x 25cm (L xWxH)
(other dimensions custom made available!)
Tube for the gassupply. This tube can be inserted into the cage by putting
it through the bars of the wire lid.
A valve in the polycarbonate box to connect the unit to an exhaust system.
(Optional for laughing-gas).
The s.s. trolley has a tray on which the gas cylinders can be placed.
A switchboard for the supply of the gas (mixure) O2 and CO2, according
a PLC pre-set program. (Optionally we can also enclude a program for the
supply of laughing-gas (N2O).

The switchboard contains:

* 1 red button: to switch the unit ON and OFF.
* 3 green buttons positioned vertically: each button activates a PLC pre-set program:
- 1) 1 minute O2 and 4 minutes CO2 (euthanasia)
- 2) 1 minute O2 and 1 minute CO2 (short intoxication) optional
-3) 1 minute laughing-gas
(A special laughing gas absorber for the gas-exhaust is required.)
* 3 green buttons positioned horizontally. For the manually supply of the different gases.
(Laughing-gas optional.)
