Efficient Virus Sampling with Gelatin Filters

Air sampling technologies offer quick detection capabilities, efficiently identifying viral particles in aerosols. After sampling, the filters dissolve in a buffer solution, allowing for RNA extraction and further analysis using techniques like PCR or serological assays. These downstream steps require proper preservation of viral particles during sampling.

Gelatin filters are especially useful for short-term sampling in controlled environments, requiring minimal preparation and compatibility with various detection methods. They reliably collect a wide range of biological aerosols, like bacteria, molds, and viruses, with studies demonstrating consistent collection effectiveness over a wide range of flow rates and high retention capability even under extreme ambient conditions.

Gelatin also acts similarly to a protective viral protein, safeguarding viruses against surface inactivation.

Advanced Air Monitoring Technology

Air sampling devices work by drawing a set volume of air through a gelatin membrane filter, capturing airborne microorganisms. Facilities looking for continuous and precise microbiological air monitoring in cleanrooms, pharmaceutical production areas, and food and beverage facilities prioritize sample preservation on the filter surface for downstream testing.

Adjustable flow rates also matter for tailoring to different environments; lower flow rates are useful for extended sampling.

Air samplers like the Sartorius MD8 use USP-approved and agar-free filters that don’t dry out during long-term sampling, which keeps the captured particles viable for testing. They also have adjustable air throughput rates for environments needing constant surveillance.

Building a Robust Testing Workflow

Once microorganisms are captured by the air sampler, downstream protocols are used for sample preparation and testing. This is where quality lab essentials like ultrapure water, filtration solutions, and pipettes help ensure the accuracy, reliability, and reproducibility of results. 

For example, contaminants in lab water used to prepare samples and run sensitive assays could interfere with viral detection. Quality filtration devices also help clarify and sterilize samples, ensuring that only the target virus is present for analysis.
