Liquid microbial aerosol sampler

The liquid impact sampler is made entirely of glass,It consists of a liquid impact bottle (intake elbow, nozzle, liquid bottle, exhaust pipe), a main unit, and a timer.

Liquid impact bottleThe structure consists of a 90 degree curved intake pipe and an outer bottle for holding the sampled liquid. The bend at the upper part of the intake pipe simulates the obstruction of aerosol particles by the human upper respiratory tract. There is a microporous nozzle at the end of the pipe, 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 liquids, microbial particles are captured.

The liquid impact sampler is particularly suitable for concentration determination in experimental air microbiology. Aerosol sampling is commonly used in experiments such as the dosage of microbial aerosols for animal infections, the recovery rate of microbial aerosol survival, the study of aerosol tracers, the dosage of human aerosol immunity, the sterilization effect of air disinfectants and sterilizers, and the retention effect of filter materials and filters.

Characteristics of liquid microbial aerosol sampler

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

2. The collected samples can be analyzed separately, divided into several parts, and measured using several methods to achieve multiple experimental objectives; A portion of the sampling solution can also be stored in the refrigerator for repeated measurements and further analysis.

3. During the sampling process, the liquid impact sampler can release multiple microorganisms from the microbial particle cluster due to airflow impact and agitation of the sampling liquid, evenly distributed in the sampling liquid. After further biological cultivation, it can accurately measure the number of microorganisms in the air.

4. High capture rate. It is particularly sensitive to small particle aerosols and can capture particles as small as 0.5 μ 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 repeatedly.
