The wider sterile mask: 21 × 9 cm with PU ear loops, for operators who need coverage past the jawline.

Construction

Twenty-one centimetres covers a broader face without gaps at the cheek. The same triple-bag protocol as the rest of the SF series keeps the airlock sequence unchanged.

Where it is used

  • Grade A/B operations
  • Isolator and RABS work
  • Aseptic filling interventions

Handling notes

Inspect the inner bag seal before transfer and record the lot at the point of use.
