Head Nose Only Units   头鼻式单元

Our Head Nose Only exposure units have a modular expandable design which allows them to be continually adapted to the customer's requirements. The basic structure consists of single segments which can be stacked on top of each other.
我们的头鼻式暴露单位采用模块化和可扩展设计这使他们能够不断调整以适应客户的需求。基础结构包括各个单个分层，可以逐层堆叠。

The validation of the equilibrium distribution and directed-flow design was carried out in 1994/2007 by Prof. Pauluhn, and in 2009 by Prof. Phalen.
Pauluhn教授（1994年和2007年）和Phalen教授（2009年）验证了系统的平衡分布和直通气流设计

Each Head Nose Only exposure unit can be equipped with the required aerosol inlet interfaces, appropriate animal cage ports, sampling and environmental sensor connections / adaptors.
每个头鼻式暴露单元可以配备需要的气溶胶入口，适当的动物笼子端口，取样和环境传感器连接/适配器。

Depending on the laboratory requirements, the units are customized for use in fume hoods or as units on casters with brakes.
根据实验室需要，单元可以被定制为在通风橱内使用或可移动的（带刹车的滚轮支架）。
