The Flotation Test can identify contaminating matter of animal origin (e.g. whole or fragmented mites and insects, or rodent hairs) in a wide range of food, feed, veterinary and dust samples.
It is the single and most effective method of confirming the presence of mites in commodities, and easily differentiates between dead and live mites.
The flotation test can be used to assess mite infestations in a diverse array of products such as:
· Fine powders (e.g. flour, dried milk, yeast)
· Granular materials (e.g. animal feed, wheatgerm)
· Compacted and pelleted materials (e.g. animal feed pellets, dairy nuts, pet food)
· Seeds and grain (e.g. wheat, barley, oilseed rape, maize, soya, rice)
· Dried fruits
· Dust (e.g. house dust, mattress dust, floor sweepings etc. for the detection of house dust mites)
· Plant material (e.g. hay, straw, wood or paper-based animal bedding)
· Flower bulbs (e.g. tulips, hyacinths)
· Veterinary samples (e.g. animal dander)
Customer samples are suspended in a careful balance of aqueous alcohol, acids and salts before percolating kerosene upwards from the base. Any animal matter present is collected on a filter paper, allowing easy examination away from the bulk sample.
