Monitoring during Viral Outbreaks
Infectious diseases represent a permanent threat to public health. The current global pandemic of COVID-19 (caused by the novel coronavirus SARS-CoV-2) has forced society to face unforeseen challenges and to adjust to a new reality. As lockdowns ease, the need to monitor the airborne viral load in critical areas is more important than ever to halt the spread of the virus.
It is Time to Address Airborne Transmission of COVID 19
This was the call out of 239 scientists to the WHO to re-investigate te airborne transmission of SARS-CoV2 with a view to the dangers posted by aerosolized particles.
Read what 239 scientists had to say!
A commentary signed by 239 scientists from around the globe are advocating preventive measures to mitigate this route of airborne transmission.

New scientific evidence is available on the transmission of SARS-CoV-2 which suggests that not only respiratory droplets but also aerosols can function as potential transmission pathways for COVID-19. Many questions remain unanswered as this infection route has yet to be definitively demonstrated, particularly in regard to transmission ‘in the absence of aerosol generating procedures, and in indoor settings with poor ventilation.
Discover Air Sampling Tools for Detection of SARS-CoV-2 in droplets as well as in aerosols
See how experts have used the Airscan monitors and Gelatine Membrane Filters in different virus detection areas!
The MD8 Air sampler and gelatin membrane filters were used in Wuhan hospitals during the Coronavirus outbreak.
Designed to detect the smallest viruses and microorganisms in your air
The MD8 air samplers, MD8 Airscan® and the portable Airport MD8, are designed to detect smallest viruses and microorganism in the air by using the unique Gelatine Membrane Filters (GMF) and BactairTM agar plates. MD8 Airscan® and Airport MD8 monitors ambient air in cleanrooms, controlled, and public areas for viable microorganisms.
The MD8 Airscan® and Airport MD8 provides non-stop, active air monitoring for at least 8 hours, using only a single gelatin membrane filter. Rule out false negative results; the proprietary, USP-approved filter retains even the smallest airborne microorganisms and monitors viability at the most accurate level.
Gelatin membrane filters
Water soluble gelatin membrane filters are the perfect way to quickly test for SARS-CoV-2. With the help of the portable MD8 air sampler, the air of all high-contamination risk areas can be sampled for coronavirus. The membrane can be dissolved in minimal volumes of water, aiding with RNA sample concentration right from the start.
- Gelatin filter solubility is ideal for rapid testing methods
- The highest retention rates for bacteria, viruses, spores, and phages
Single use or with reusable holder
Our gelatin membrane filters are available with a single-use filter base of 80 mm diameter and also with stainless steel reusable filter holders, suitable for different diameters.
Gelatine filters, in conjunction with the MD8 air sampler, offers the following features and benefits:
- “Absolute” retention rate (99.9995% for Bac. sub. niger spores, 99.94% for T3 phages)
- The filter maintains the viability of collected microorganisms for a relevant and meaningful sampling time
- Gelatine filters are completely water soluble, a requirement for virus sampling

Sampling of Human Pathogenic Viruses from Air by Gelatin Membrane Filters and Subsequent Detection by PCR Analysis
Outbreaks of infectious diseases represent an important global public health issue but also pose far reaching challenges and threats to global economies and healthcare systems. Viral infections without antiviral treatments are particularly menacing, hence understanding infection sources and routes of transmission and how these contribute to the spread of disease can facilitate effective prevention and adoption of control measures.

Quantitative Detection of Bacteriophage Loads in the Ambient Air of Dairies
Despite worldwide efforts in developing phage-resistant starter cultures, bacteriophages are still the main cause of acid interference and, thus, product spoilage in dairies. Complete and careful phage monitoring is essential to replace phagesensitive cultures with phageresistant strains on time and to localize the internal source of infection.
