A planktonic bacteria sampler is a device used to collect airborne microorganisms, widely used in industries such as food and healthcare that have strict requirements for air quality.
By using a built-in air pump to draw air into the sampler, microbial particles in the air are rapidly impacted onto the agar surface inside the culture dish (diameter 90mm), achieving microbial capture. The device is equipped with 397 micropores (diameter 0.7mm) to ensure impact efficiency.
Based on the Anderson impact principle, the suction device of the sampler sucks in air through a porous sampling head, and microorganisms in the air are impacted and adhere to the agar surface inside the culture dish due to inertia. Subsequently, the types and quantities of airborne microorganisms were determined by counting and analyzing the colonies formed after cultivation.
Technical Features
Constant current sampling: Adopting the standard impact method sieve type working mode, equipped with an air flow sensor, it can automatically measure the ambient temperature and atmospheric pressure, and automatically maintain constant current according to changes, with high flow control accuracy.
Easy to operate: It adopts a dot matrix LCD display screen, Chinese menu operation, and has a large capacity data storage function, which can meet the storage of hundreds or even thousands of sampling data. It also has a USB interface that can automatically calibrate the sampling flow rate.
Strong adaptability: AC/DC dual-use, built-in high-energy lithium battery, can be equipped with a dedicated triangular bracket, adjustable sampling height, can be used at different temperatures, altitudes, and atmospheric pressures, without the need for recalibration of flow rate.
Appearance and Cleaning
1. Regularly clean the casing: The casing of the planktonic bacteria sampler will absorb dust, stains, etc., and should be wiped regularly with a clean damp cloth. For stubborn stains, a mild cleaning agent can be used, but care should be taken to avoid the cleaning agent entering the interior of the instrument. After cleaning, wipe dry with a dry cloth to prevent moisture residue from causing rust or damage to the casing.
2. Check the integrity of the appearance: Before and after each use, carefully inspect the appearance of the sampler for damage, cracks, or deformation. If any loose or damaged components are found, they should be tightened or replaced in a timely manner to avoid affecting the normal operation of the instrument.
