1. Power Source Description
1.1 Product Overview
The Vante Model 4600 RF Tube Sealer is a compact, portable device which employs
radio frequency (RF) to make uniform, quality seals on a variety of tubing sizes without
power adjustment by the user. The System consists of the Model 4600 Power Source
(“the Power Source”) and can be teamed with either the Model 4105 hand-held,
manually-activated sealing head or the Model 4605 bench-top segmenting sealing head
(“the Sealing Head”) which creates a seal that is formed by the sealing head jaws in such
a way as to make segment separation easy and uniform.

1.2 Theory of Operation
The physical properties of PVC and EVA plastic tubing (and other RF-reactive
thermoplastic materials) cause it to dielectrically heat at a molecular level in the presence
of RF energy. This energy causes the plastic to soften due to the friction of the vibrating
molecules. In this softened condition, the plastic becomes sealable because the molecules
are free to intermingle under the application of external forces, such as compression. If
allowed to cool while the forces are applied, the material will be permanently reshaped.
The Power Source is an instrument that, when actuated, generates a controlled amount of
RF energy at the sealing head while mechanically compressing the tubing across its
diameter during the dielectric sealing and forming process. When the energy is removed
and the tubing is allowed to cool under compression, a permanent seal is produced.
The Power Source produces a minimum of 150 Watts of RF power, the frequency of
which is controlled by a solid-state oscillator/amplifier operating at 40.68 MHz. The RF
energy level and seal time are controlled by means of a proprietary solid-state circuit
