Your diluent ready in minutes!
instaBAG is a filter bag which includes a dehydrated pre-dosed media (supplemented Fraser ½), allowing a 2-in-1 process. Skip the time-consuming media preparation.

Just add water
Ready-to-use bag with pre-dosed dehydrated media in the bag. Just add the sample and sterile and purified water. The diluent dissolves itself during blending. The dehydrated media is buffered peptone water. instaBAG can therefore be used to dilute any sample to count all microorganisms. instaBAG is available in BPW 90 mL and 225 mL.

Ideal for Listeria analyses
The pre-dosed dehydrated media is supplemented Fraser ½. instaBAG Fraser ½ is used for primary selective enrichment or as a diluent for the detection and enumeration of Listeria monocytogenes and Listeria spp. (ISO 11290-1, ISO 11290-2) in food and environmental samples.

The advantages of a filter bag
Filtration is done during blending. There is no need to wait for sedimentation of the debris to pipet. The filtrate is particle-free, so there is no debris on the Petri dish. Reading is thus facilitated and the results more accurate.

Applications
instaBAG supplemented Fraser ½ is used in the food industry and public institutes research. In Fraser, it allows the suspension of solid samples of 25 g diluted at 1/10th for the detection of Listeria monocytogenes. This selective media is already supplemented and ready-to-use. It is validated according to ISO 11133.
