Currently there are different techniques to plate, and each one of them has a specific use and properties. Some also require prior procedures such as serial dilution to be performed. So, although we have different ways of plating or monitoring microbial growth in culture, four of them are the most used: the spread plate, the pour plate, the drop plate, and the spiral plate.
The concern about indoor air quality has grown, not only in air-controlled environments such as pharmaceutical manufacturing areas, hospitals, and food processing facilities, but also in homes and workplaces. Deteriorated indoor air quality may cause adverse effects such as allergies, asthma, or sick building syndromes. Therefore, controlling the microbiological quality of the air is essential and several sampling methodologies have been widely employed. This leads us to the origin of IUL's air sampler Spin Air, an internal impaction-based indoor air sampler with a groundbreaking technology able to identify and quantify airborne microorganisms with an unbeatable accuracy and precision.
The Spiral Plater is a two-in-one method: dilutor and plater at the same time. The Spiral Plater is one of the most time and waste volume saving methods of inoculation, that is why more and more microbiological laboratories are using Spiral Platers for bacterial determination.
