INTERSCIENCE presents an evolution of its BagFilter® P 400, the best-selling side filter bag, now with Closing Zone marking which allows the user to instinctively and precisely position the closing bar for a guaranteed leakproof seal.

Key points:

• Safety of the sample and the operator
• Time saving in handling
• Guaranteed cleanliness of incubators

This patent-pending visual enhancement for the technician undoubtedly improves incubation in the laboratory by eliminating capillary rise during the incubation stage of enrichment.

“Incorrect positioning of the closing clip on the bag leads to capillary rise of the sample. Some customers have had cases of cross-contamination during the enrichment stage. The Closing Zone marking is an improvement that provides security for the technician and the samples.” explains Manon Laborie, Application Manager.

Indeed, when testing for pathogens such as Listeria or Salmonella, it is necessary to incubate the sampled bags for the enrichment stage. Laboratory operators have noticed that during the incubation time of the enrichment, the bags, even when closed, spill all or part of their contents into the ovens. Poorly positioned and poorly clipped, the potentially contaminated sample leaks out of the bag by capillary action, the “siphon effect”, due to the presence of the filtering wall.

In order to secure the handling of the technician and the sample, the correct positioning of the closure is an important point. This prevents cross-contamination, unusable samples and loss of time.

The new Closing Zone marking offers time saving, efficiency and security when positioning the BagClip® at the height precisely defined by the marking, it is immediately recognizable by the technician.

Resulting from a collaboration with a customer problem, the Closing Zone marking has been adapted to all types of closing systems. BagFilter® P - Closing Zone - is now offering peace of mind to hundreds of teams in analytical production.
