Doboy B-500M Validatable Band Sealer

The B-500M continuous band sealer provides high quality validatable heat seals for medical packaging applications.  It is typically used to seal Tyvek / Poly, Foil, and polyethylene pouches and bags.

The B-500M provides heat, temperature, and speed data to operators, allowing it to be used in applications requiring sealing process validation.

Designed for precision sealing of medical components in clean room environments!

The B-500M design has now been replaced by the Doboy B-550 Band Sealer.

Ideal for medical packaging applications like: surgical kits, suture packs, catheter kits, surgery supplies, sterile components, sterilizable packages, etc.
