Airborne Dust and Bacteria Sampler - Handheld High Efficiency Porous Inhalation Microbial Sampling Equipment

In industries such as pharmaceuticals, healthcare, and food processing that require strict clean environments, controlling microbial contamination in the air is a key link in ensuring product quality and safe production. The airborne dust and bacteria sampler, as an efficient sampling device based on modern microbial detection technology, provides a reliable technical means for environmental microbial monitoring through innovative handheld design and porous inhalation sampling principle.

The Importance and Technical Challenges of Clean Environment Monitoring

Floating bacteria in the air are one of the main factors affecting the quality of clean environments. The concentration of microorganisms in the air is directly related to product quality and medical safety in places such as drug production, operating rooms, and biological laboratories. The traditional methods for detecting settling bacteria have problems such as low sampling efficiency and poor representativeness, making it difficult to meet the precise requirements of modern clean environment monitoring.

The technological innovation of the airborne dust and bacteria sampler lies in its use of a porous inhalation sampling design, which can quickly and accurately collect microbial particles in the air. This sampling method not only improves detection efficiency, but also accurately reflects the microbial contamination status of clean environments, providing scientific basis for environmental control.

Engineering Innovation in Handheld Design

The handheld design of modern airborne dust and bacteria samplers embodies a humanized engineering concept. The instrument adopts a split structure, with a collection port, sampling seat, and air pump in the upper part, and a controller and battery integrated in the lower part. The overall weight is only 1.6kg, and the size is 21.5 × 14 × 24.5cm, which is convenient for operators to carry and use.

The sampling port and housing are made of high-quality aviation aluminum material, with a closed cell surface treatment, which not only ensures the lightweight of the equipment, but also facilitates sterilization and disinfection before use. This material selection ensures both the durability of the equipment and meets the hygiene requirements of a clean environment for the equipment.

In terms of power system, the floating air dust and bacteria sampler is equipped with a 6000mAh high-capacity lithium battery, which supports continuous sampling for 8 hours. It also has AC/DC dual-use function, ensuring the continuous working ability of the device in various environments.

Principle of porous inhalation sampling technology

The airborne dust and bacteria sampler is designed based on the principle of particle impact and the theory of isokinetic sampling. When the equipment is working, the air carrying dust bacteria passes through the micropores at a high speed of 100L/min ± 5%, and the microbial particles collide with the agar surface inside the culture dish due to inertia. The impact wind speed of the sampling hole reaches 12m/s, and the flow velocity at the sampling port is 0.35m/s, which is consistent with the wind speed in the clean room, achieving constant velocity sampling.

The technical advantages of this sampling method are:

Direct sampling avoids the loss of microorganisms during the sampling process

Isokinetic sampling ensures sampling representativeness and accurately reflects the concentration of microorganisms in the clean room

Porous design improves sampling efficiency and ensures uniform distribution of microorganisms

After collection, live microorganisms undergo kinetic rehydration during the cultivation process, which enables rapid growth, shortens detection time, and improves detection efficiency.

Intelligent Control System and Data Processing

The airborne dust and bacteria sampler is equipped with a 3.5-inch color touch screen, providing an intuitive operating interface. The LCD display screen displays important parameters such as sampling amount and sampling time in real time. Operators can flexibly set the sampling amount according to their needs, with a range of 1-9999L adjustable.

The data management system of the device has the following characteristics:

Support storing sampling parameters by group for easy data management

Built in thermal printer, capable of instantly printing detection data

Equipped with upper computer software, exporting data through USB interface

Support both Chinese and English operation interfaces to meet different user needs

These intelligent functions greatly enhance the convenience of using the airborne dust and bacteria sampler, while also ensuring the accuracy and traceability of the detection data.

Industry application and standard compliance

The airborne dust and bacteria sampler strictly follows relevant industry standards:

GB/T16293-2010 Test method for planktonic bacteria in clean rooms (areas) of the pharmaceutical industry

ISO14698-1/2 Control of Biological Pollution in Cleanrooms and Related Control Environments

GMP Good Manufacturing Practice for Drug and Food Production Quality Management

In the pharmaceutical industry, this equipment can be used for microbial monitoring in key areas such as sterile production areas and clean corridors; In the field of hospitals, air quality testing is applicable to medical environments such as operating rooms and ICU wards; In the food processing industry, it can be used for environmental monitoring in production workshops and packaging areas. In addition, airborne dust and bacteria samplers also play an important role in the production of biological products and public health monitoring.

Convenience of operation and maintenance

The design of the airborne dust and bacteria sampler fully considers the user experience. When replacing the culture dish, simply remove the sampling port to complete the operation, and the entire process is simple and fast. The daily maintenance of the equipment mainly focuses on cleaning and disinfecting the sampling port and charging the battery, with low maintenance costs.

The program of the instrument supports switching between Chinese and English, making it convenient for operators with different language backgrounds to use. The data export function enables easy historical analysis of detection results, providing data support for continuous improvement of environmental quality.

The airborne dust and bacteria sampler provides an efficient and reliable solution for microbial monitoring in clean environments through innovative handheld design and porous inhalation sampling technology. Its excellent technical performance and convenient operational characteristics make it an important tool for environmental monitoring in various industries. With the continuous improvement of quality control requirements, airborne dust and bacteria samplers will play a more important role in ensuring production environment safety and improving product quality.
