There are some types of test materials, and there are some samples that are expensive and valuable, and a sample that must be carefully administered through oral and skin. The inhalation experiment of these testing material uses a nose -cracked dewry trial device. This device contains experimental animals in a special holder, and only the nose of the experimental animal is exposed in the chamber.

● The holder is made of transparent acrylic, and the ecology of experimental animals can be observed from the outside. (Practical new plan)
● Because the chamber rotates, it is easy to attach and remove the holder.
● Chamber and holder are completely sealed and can be used for inhalation tests for strong toxic substances.
● Unlike the whole body, the effects of the skin can be ignored.
● Since a conical case is inserted inside, there is no backflow of airflow and the sample is small.
● Guinea pigs and hamsters are also possible.

* The dust feeder (generator) and compressor in the photo are optional. * In -sucker in the draft for radiation substances is also designed and manufactured. * The price is a reference price.
