Microbial aerosol sampler

The liquid impact microbial aerosol sampler (also known as the liquid impact sampler) is made entirely of glass and consists of a sampling bottle, an intake bend, a nozzle, and a controller

The structure consists of a 90 degree curved intake pipe and an outer bottle for sampling liquid. The bend on the upper part of the intake pipe simulates the obstruction of aerosol particles by the upper respiratory tract of humans. At the end of the tube, there is a micro hole nozzle, which accelerates the airflow to reach the speed of sound. The jet airflow is used to collect microbial particles in the air into the liquid sampling medium. Due to the adhesiveness of the liquid, microbial particles are captured.

The liquid impact sampler is particularly suitable for concentration determination in experimental air microbiology. Commonly used for aerosol sampling in experiments such as the dosage of microbial aerosol animal infection, recovery rate of microbial aerosol survival, research on aerosol tracers, dosage of human aerosol immunity, sterilization effect of air disinfectants and disinfectors, and retention effect of filter materials and filters.

Features:

1. Suitable for sampling high concentration microbial aerosols, the collected samples can be diluted to accurately determine the concentration of airborne microbial particles.

2. Can analyze the collected samples separately, divide the samples into several parts, and use several methods to measure them simultaneously, achieving multiple experimental objectives; A portion of the sampling solution can also be stored in the refrigerator for repeated testing and further analysis.

3. During the sampling process, the liquid impact sampler can release multiple microorganisms from microbial particle clusters due to airflow impact and agitation of the sampling solution, which are evenly distributed in the sampling solution. After further biological cultivation, the number of microorganisms in the air can be accurately measured.

4. High capture rate. Especially sensitive to small particle aerosols, it can capture 0.5μ Small particles of m.

5. The sampling solution has a protective effect and can also sample fragile microorganisms such as viruses and rickettsia.

6. The liquid impact sampler is made of glass fired, with a simple structure, low price, convenient use, easy disinfection, and can be reused.

Sampling flow rate: 3-30 liters/minute Sampling liquid volume: 10-20 milliliters
