Product Description:

TYK-3HLiquid impact sampler(Constant current version)correctBy the host andAll glass manufacturingofIt consists of a sampling bottle, an intake elbow, a nozzle, an exhaust pipe, and a flow meter. The structure has a presentation90 degree curved intake pipe and onegroupOuter bottle for sampling liquid. The bend on 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 tube, The airflow increases at this speed to reach the speed of sound, and the microbial particles in the air are collected in the liquid sampling medium using jet airflow. Due to the adhesiveness of liquids, microbial particles are captured.

TYK-3HLiquid impact samplers are 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.

productcharacteristic ：

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

7Sampling traffic:7-12.5 liters/minute Sampling volume: 10-20 milliliters（(Electronic constant current digital constant current constant voltage; Built in high-precision sensors; The instrument can be self calibrated, and the flow rate is not affected by voltage fluctuations and gas resistance changes)

8Flow error:≤±5%

9. Load capacity: ≥ 15000pa

10. Timer mode: ① Loop sampling (extra large 99 cycles), can cycle volume or time sampling, set sampling time, pause time, and number of cycles.

② Manual sampling: After setting the sampling flow rate, you can directly sample, start timing, and manually shut down.

③ Timed sampling, set the sampling time, and stop sampling when the time is up.

④ Fixed volume sampling (extra large 1000L), set the sampling volume for sampling.
