Microisolator cage type II PC

The UNO cage and filtertop system has been developed for two purposes:

  1. To protect animals during transport: by placing a filtertop on the animal cages during any kind of transport, the animals can be protected against contamination from the outside environment.
  2. To create a micro isolator: the cage and filtertop unit can be regarded as a microisolator in which animals can be held permanently. It is a simple alternative to the complex barrier room system creating the barrier at cage level.

Microisolator cage adventages

  • No cross contamination from animals of different species in the same room;
  • Cages can be moved safely from the LF bench to other areas (controlled or not controlled) because the isolation stays intact;
  • Infection from personnel is no longer possible;
  • Different species can be studied in the same room if necessary;
  • Experimental infection with different microbes can be studied in the same room.

The maximum permissible number of animals during experiments in a cage depends on their body weight:


  • up to 20 g – 6 pcs
  • 20 g to 25 g – 5 pcs
  • 25 g to 30 g – 4 pcs
  • above 30 g – 3 pcs

Cage type II

  • Material: polycarbonate , transparent
  • Height: 140 mm
  • Dimensions – bottom: 252 x 167 mm ( length x width)
  • Floor area: 375 cm2
  • Weight: 485 g

Wire lid

  • The dividing plate in the feeder is part of the lid
  • Hangs on the rims of the cage - no retainers are necessarry
  • Materials: stainless steel


  • Material: polycarbonate, transparent
  • Replaceable filtersheet included, made of polyester


All parts of the microisolator cage can be repeatedly sterilized in a steam autoclave at 120 ºC for 20 minutes.
Filtersheet has to be replaced after approx. 10 sterylization cycles because of wear.
