Made from lightweight anodised aluminium. Both the lid and base are perforated and protected by reusable filters with each filter validated for 1000 cycles which allow steam penetration but not micro-organisms delivering a sterile field for the components stored inside.

The clip on lid incorporates a silicone seal which is impervious to micro-organisms.

Paper labels to identify kits and safety padlocks add to peace of mind. A fingered silicone mat will prevent instruments from damaging each other.
