BRUSH MAS100空氣采樣器是一款用于微生物監(jiān)測的設(shè)備，它基于安德森撞擊法原理，通過高性能的抽吸裝置抽取空氣，使微生物撞擊附著在標(biāo)準(zhǔn)培養(yǎng)皿中瓊脂培養(yǎng)基的表面，完成采樣周期后，培養(yǎng)皿可以在適宜條件下培養(yǎng)以確定菌落總數(shù)。該設(shè)備具有多個(gè)特點(diǎn)，包括經(jīng)濟(jì)性、便攜易用性、規(guī)范性、穩(wěn)定性和精確性 。

此外，MAS-100系列中還包括MAS-100 CG Ex?，這是唯一獲準(zhǔn)在2區(qū)爆炸危險(xiǎn)區(qū)域使用的壓縮氣體微生物空氣采樣器，它使用兩個(gè)傳感器來采集樣品，確保采樣的安全性、簡單性和準(zhǔn)確性 。

MAS-100 NT是另一個(gè)型號(hào)的空氣浮游菌采樣器，它適用于藥廠、藥檢所和衛(wèi)生防疫區(qū)域等行業(yè)，具有設(shè)計(jì)簡潔且準(zhǔn)確的特點(diǎn)，流量范圍為1-2000升，流量測量精度為100升/分鐘±2.5% 。

MAS-100 Eco Airsampler是針對食品工業(yè)設(shè)計(jì)的微生物空氣采樣器，它經(jīng)濟(jì)、小巧且輕便，適用于環(huán)境空氣的微生物監(jiān)測 。

這些設(shè)備廣泛應(yīng)用于室內(nèi)外大氣環(huán)境監(jiān)測、疾病預(yù)防、安監(jiān)、軍事、氣象、科研教學(xué)、冶金、化工、鐵路、建材等領(lǐng)域的衛(wèi)生監(jiān)測和評價(jià)，也可與有關(guān)儀器配套使用

BRUSH MAS100空氣采樣器的工作原理基于安德森撞擊法，該方法通過抽取空氣通過一個(gè)多孔蓋，氣流中的微生物撞擊并附著在標(biāo)準(zhǔn)培養(yǎng)皿中瓊脂培養(yǎng)基的表面。具體來說，空氣攜帶的顆粒以一定速度撞擊瓊脂表面，這一過程相當(dāng)于安德森原理的5級(jí)，確保大于1微米的顆粒全被收集。完成采樣周期后，將培養(yǎng)皿放置在適宜條件下培養(yǎng)，以確定菌落總數(shù)。

MAS-100 NT型號(hào)的采樣器具備內(nèi)置的風(fēng)速流量計(jì)，用以連續(xù)監(jiān)測進(jìn)氣體積，并自動(dòng)調(diào)整抽氣速度以保證每分鐘采樣量為100升。這樣，即使遇到外界因素干擾或培養(yǎng)皿過滿導(dǎo)致的局部進(jìn)氣阻塞，系統(tǒng)也能自動(dòng)調(diào)節(jié)采樣速度，確保采樣精度。

此外，MAS-100系列采樣器的設(shè)計(jì)目標(biāo)是建立一個(gè)小巧、易于操作、可靠且基于標(biāo)準(zhǔn)培養(yǎng)皿即可使用的系統(tǒng)，使其適用于無菌室和潔凈室的嚴(yán)格要求，以及制藥業(yè)、化妝品業(yè)、食品行業(yè)和環(huán)境監(jiān)控領(lǐng)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
