Advanced Blade Module
Stainless steel construction which permits continuous uninterrupted welding with no jamming.

User Interface with LCD Touch Screen Display
LCD color touch (4″ x 3″) screen display provides operators with step by step instructions for performing a weld. Available in English, Spanish, French, German, Portuguese and Italian.

Infrared Heating Element
Designed for continuous operation while maintaining a high temperature for producing sterile welds.

Patented Tube Holder Clamps
The unique clamp design strips fluid away from the weld site while keeping the tubes securely in place. This process can help eliminate blood cell necrosis in blood products.

Lid Lock Mechanism
Protects operators during the welding process and inhibits accidental or unintentional interruption of the weld.
