- dose adjustment means makes it possible in particular to change the dose depending on the animal. For example, if the tests involve fifteen mice, the dose remains the same from one mouse to another. But if the tests involve fifteen mice and fifteen rats, then there is no need to change devices when changing animals, thanks to the dose adjustment means.
- the dose adjustment means also make it possible to adjust the dose as a function of the drug, for example if the tests relate to fifteen mice to be treated with a drug A dosed at 5 ⁇ L, and fifteen mice to be treated with a drug B dosed at 10 ⁇ L.
- such dose adjustment means allow fine adjustments within a small dose, for example between 5 and 20 ⁇ L.
- an interchangeable hollow sleeve 23 to define the metering chamber 21 also makes it possible to modify the volume of the dose. Typically, this type of dose adjustment makes it possible to go from a dose of 5 to 20 pL to a dose of 40 to 60 pL. Of course, these values are not limiting and are given only by way of example.
