【INTRODUCTION】The filter membrane preservation box is specially designed for the sampling of atmospheric particulates and the separate storage of single filter membrane, so as to avoid the problems such as particulate loss on the filter membrane, deformation of the filter membrane and pollution of the sample caused by the way of storing the sampled filter membrane in aluminum foil paper bags, plastic bags, folding clips, etc.

【MATERIAL】The raw material of the filter membrane box is new polystyrene (inert material), which will not pollute the filter membrane with particles collected.

【PURPOSE】It is used for convenient storage, transportation and fixing of filter membrane.
