Particulate Sampling Filters
Gelatin Filters Maintain Viability of Collected Microorganisms
ABOUT Using Gelatin Filters in the Button Sampler For maximum microorganism survivability and superior collection of inhalable-size bioaerosols, use sterile gelatin filters with the SKC Button Sampler. The Button Sampler features a unique inlet that contains evenly spaced holes that act as sampling orifices for multidirectional sampling. The proximity of the filter to the inlet minimizes transmission losses and provides equal distribution of particle loading and low intersample variation. Combining the Button Sampler with the nurturing properties of gelatin filters creates a sampler that is most efficient at collecting inhalable bioaerosols for viable or non-viable analysis. See page 93 for more information on the Button Sampler.
Absolute retention rate • 99.9995% for Bacillus subtilis var. niger spores‡ • 99.94% for T3 phages (coli phages)‡ • 99.9% T1 phages (coli phages)‡
High moisture content • Maintain microbe viability for short sampling periods
Completely water-soluble • Dissolve easily when placed on agar • Prerequisite for virus sampling
Pre-sterilized by gamma irradiation Ideal for monitoring in pharmaceutical plants Can be used to monitor in areas where disinfectants or antibiotics are present
The unique properties of Gelatin Filters provide unequalled bacteria retention levels for quantitative analysis. Sampling with gelatin filters is easy, efficient, and can provide information about relative changes in microorganism concentration throughout the day. While sampling microbes with traditional filter materials has been known to reduce culturability due to desiccation, the high moisture content of gelatin filters helps to maintain microorganism viability for sampling periods up to 30 minutes. Gelatin filters dissolve easily when placed on agar, allowing for a gentle transition from sample medium to growth medium. For maximum culturability and superior collection of inhalable-size bioaerosols, combine gelatin filters with the SKC Button Sampler, see left.
