New Brunswick Biological Air Sampler STA-204
*Used, includes power supply for vacuum pump only*
Slit-To-Agar (STA) air samplers have become a lab standard
for detecting airborne microbial contamination. New
Brunswick Scientific has improved the original designs with
two new models that provide a dynamic sampling range,
more precise control and easier validation. STA 203 and STA
204 Models have been successfully used in a variety of environments
including pharmaceutical facilities, hospitals, food
and cosmetics labs, and in the detection of terrorist-dispersed
