This air sampler in microbiology features a user-friendly interface with a clear and concise design. Users can flexibly set the sampling volume and utilize a delayed sampling function, ensuring data accuracy.
Uniform Micropore Impaction
- This air sampler for microbiological monitoring is based on the Anderson impaction principle (Design level is 3). It uses specially designed dense micropores to uniformly impact air onto the culture dish, effectively reducing colony overlap and improving microbial collection efficiency and counting accuracy.
- The air velocity at the sampling port matches the air velocity within the cleanroom, ensuring that the collected microbial samples accurately reflect the true microbial concentration within the cleanroom.
- The sampling volume can be freely set from 1 to 9999L, and it features a sampling delay function to effectively avoid interference from personnel operations in the clean environment, ensuring data accuracy and reliability.
This Microbial Sampler is Worry-Free and Reliable
- It features a medical-grade touchscreen LCD that supports settings for volume, flow rate, date, and sampling delay, making operation intuitive and simple.
- This air sampling device can automatically store up to 1000 sets of sampling history records. Each record includes detailed sampling time, sequence number, and volume, and supports data export via USB flash drive.
- The sampling head is detachable and washable; clogged micropores can be cleaned with a brush. The device boasts a simple design that is shockproof and splash-proof, ensuring strong long-term stability.
Applications
Air samplers have a wide range of applications, which can be summarized into four main areas: In environmental monitoring, they are used to track air quality in cities and regions over a long period of time and assess the status of pollutants such as PM2.5 and ozone; in industrial safety, they monitor toxic and harmful gases and dust in working environments such as chemical plants and mines in real time to protect occupational health; in public health, they provide a basis for disease prevention and control and environmental sanitation; and in fire early warning systems, they enable early warning of fires to protect life and property.

Q1: What are the Key Parameters of an Air Sampler?
A1: The core parameters of an air sampler include: sampling flow rate (including stability and accuracy, with constant/medium/low flow rates to suit different scenarios), sampling time (precisely settable and cumulatively timed), and compatibility with the sampling medium (compatible with filter membranes, adsorption tubes, etc.). In addition, flow rate calibration accuracy, negative pressure tolerance, operating temperature and humidity range, air path sealing, and the battery life of portable models and the continuous operation stability of stationary models directly affect sampling accuracy and applicable scenarios, making them key selection criteria.
Q2: What is the Correct Operating Procedure for an Air Sampler?
A2: Before the operation, check the air circuit sealing, battery/power supply status, and calibrate the flow rate. Install the appropriate filter membrane or adsorption tube as needed, ensuring a secure and leak-free installation. Set the sampling flow rate, time, and other parameters, and aim the sampling head at the target area (avoiding obstructions and strong airflow). After starting the device, observe its operating status. Avoid touching or moving the instrument during sampling. After sampling, promptly remove the collection medium and seal the label. Turn off the device, clean the sampling head and air circuit, and record the usage to ensure sample integrity and future device usability.
Q3: What Factors can interfere with the Use of Air Samplers?
A3: How often the probe of a dew point meter needs to be cleaned depends on a variety of factors, including the environment in which it is used, the frequency of use, the cleanliness of the sample gas, and the specific requirements of the instrument. Here are the steps to clean the probe. Air samplers are susceptible to interference from multiple factors: Environmentally, high temperature, high humidity, and strong airflow can affect sampling stability; dust or corrosive gases may clog the air path and damage components. Operationally, flow calibration deviations, improper installation of the sampling medium, and obstruction or improper positioning of the sampling head can lead to sample distortion. Equipment-wise, air path leaks, pump aging, sensor drift, and insufficient battery life (for portable models) can reduce sampling accuracy. Furthermore, unreasonable sampling time settings and ambient electromagnetic interference can also interfere with normal operation and data accuracy.
Tips: How often should the Air Sampler be performed?
The frequency of the air sampler is not fixed but should be determined comprehensively based on the monitoring objectives, environmental risk levels, and regulatory requirements. For locations requiring continuous cleanliness maintenance, such as pharmaceutical workshops and hospital operating rooms, strict, regular monitoring should be implemented, potentially daily, weekly, or per production batch. For general public health monitoring or office spaces, routine surveys can be conducted quarterly or annually. Emergency sampling must be conducted immediately in the event of an epidemic risk, environmental complaints, or major events such as construction or disinfection. Furthermore, resampling and verification should be performed after any maintenance or alteration of a cleanroom or ventilation system.
