BRUSH MAS100空气采样器是一款用于微生物监测的设备，它基于安德森撞击法原理，通过高性能的抽吸装置抽取空气，使微生物撞击附着在标准培养皿中琼脂培养基的表面，完成采样周期后，培养皿可以在适宜条件下培养以确定菌落总数。该设备具有多个特点，包括经济性、便携易用性、规范性、稳定性和精确性 。

此外，MAS-100系列中还包括MAS-100 CG Ex®，这是唯一获准在2区爆炸危险区域使用的压缩气体微生物空气采样器，它使用两个传感器来采集样品，确保采样的安全性、简单性和准确性 。

MAS-100 NT是另一个型号的空气浮游菌采样器，它适用于药厂、药检所和卫生防疫区域等行业，具有设计简洁且准确的特点，流量范围为1-2000升，流量测量精度为100升/分钟±2.5% 。

MAS-100 Eco Airsampler是针对食品工业设计的微生物空气采样器，它经济、小巧且轻便，适用于环境空气的微生物监测 。

这些设备广泛应用于室内外大气环境监测、疾病预防、安监、军事、气象、科研教学、冶金、化工、铁路、建材等领域的卫生监测和评价，也可与有关仪器配套使用

BRUSH MAS100空气采样器的工作原理基于安德森撞击法，该方法通过抽取空气通过一个多孔盖，气流中的微生物撞击并附着在标准培养皿中琼脂培养基的表面。具体来说，空气携带的颗粒以一定速度撞击琼脂表面，这一过程相当于安德森原理的5级，确保大于1微米的颗粒全被收集。完成采样周期后，将培养皿放置在适宜条件下培养，以确定菌落总数。

MAS-100 NT型号的采样器具备内置的风速流量计，用以连续监测进气体积，并自动调整抽气速度以保证每分钟采样量为100升。这样，即使遇到外界因素干扰或培养皿过满导致的局部进气阻塞，系统也能自动调节采样速度，确保采样精度。

此外，MAS-100系列采样器的设计目标是建立一个小巧、易于操作、可靠且基于标准培养皿即可使用的系统，使其适用于无菌室和洁净室的严格要求，以及制药业、化妆品业、食品行业和环境监控领域等

The BRUSH MAS100 Air Sampler is a device for microbial monitoring based on the Anderson impact method principle. It uses a high-performance suction device to extract air so that the microbial impact attaches to the surface of the AGAR medium in a standard petri dish. After the sampling cycle is completed, the dish can be cultured under suitable conditions to determine the total number of colonies. The device has several characteristics, including economy, portability, normalization, stability and accuracy.

In addition, the MAS-100 series includes the MAS-100 CG Ex®, the only compressed gas microbial air sampler approved for use in Zone 2 explosion hazard areas, which uses two sensors to collect samples, ensuring safety, simplicity and accuracy of sampling.

The MAS-100 NT is another type of aeroplankton sampler, which is suitable for pharmaceutical factories, drug inspection offices and health and epidemic prevention areas. It has a simple and accurate design, with a flow range of 1-2000 liters and a flow measurement accuracy of 100 liters/min ±2.5%.

The MAS-100 Eco Airsampler is a microbiological air sampler designed for the food industry. It is economical, small and lightweight for microbiological monitoring of ambient air.

These equipment are widely used in indoor and outdoor atmospheric environment monitoring, disease prevention, safety supervision, military, meteorology, scientific research and teaching, metallurgy, chemical industry, railway, building materials and other fields of health monitoring and evaluation, can also be used with related instruments

The BRUSH MAS100 air sampler works based on the Anderson impact method, which works by pumping air through a porous cover where microbes in the airflow strike and attach to the surface of an AGAR medium in a standard petri dish. Specifically, air-borne particles hit the surface of the AGAR at a certain speed, a process that is equivalent to level 5 of Anderson's principle, ensuring that particles larger than 1 micron are all collected. After completing the sampling cycle, the petri dish was placed under suitable conditions for culture to determine the total number of colonies.

The MAS-100 NT sampler has a built-in air flow meter to continuously monitor the intake volume and automatically adjust the pumping speed to ensure a sampling rate of 100 liters per minute. In this way, the system can automatically adjust the sampling speed to ensure the sampling accuracy even if the local intake is blocked by external factors or the petri dish is too full.

In addition, the MAS-100 series sampler is designed to be small, easy to operate, reliable and ready to use based on standard petri dishes, making it suitable for the strict requirements of aseptic and clean rooms, as well as the pharmaceutical, cosmetic, food and environmental monitoring industries
