Portable Air Microbial Sampler | Touch Screen Control

Microbial pollution in the air is a key factor affecting the quality control of clean environments. This article is based on the principle of impact sampling, systematically analyzing the technical characteristics, performance advantages, and practical application solutions of air microbial samplers, providing professional references for clean environment monitoring in industries such as pharmaceuticals, healthcare, and food.

The Importance of Air Microbial Samplers

Microbial contamination in the air directly affects drug safety, medical quality, and food hygiene. The traditional natural settlement method has limitations such as low efficiency and poor representativeness. The air microbial sampler adopts a porous inhalation design to achieve constant velocity sampling, which can accurately reflect the concentration of microorganisms in clean environments and provide scientific basis for environmental control.

This air microbial sampler strictly follows the requirements of standards such as GB/T16293-2010 and ISO14698, and adopts a sampling design that conforms to aerodynamic principles. It is an important tool for monitoring microorganisms in clean environments.

Working principle and technical characteristics

1. Core technical principles

Based on the principle of particle impact, contaminated air passes through micropores at a velocity of 12m/s

Adopting constant velocity sampling technology, the sampling port flow rate is 0.35m/s, which is consistent with the clean room wind speed

Live microorganisms grow rapidly on agar medium through kinetic rehydration process

2. Instrument structure design

• Split structure: The upper part is the sampling system, and the lower part is the control system

The sampling port is made of aviation aluminum material, with a closed cell surface treatment for easy disinfection

Handheld design that conforms to ergonomics, weighing only 1.6kg

Technical advantages and performance parameters

1. Sampling performance

Sampling flow rate: 100L/min ± 5%, ensuring sampling efficiency

• Set sampling volume: 1-9999L adjustable to meet different scene requirements

Using standard 90mm culture dishes with strong compatibility
