Blood Bag Tube Sealer Manufacturer,Supplier and Exporter in India
Product Code : EL-BBE-3550
Jlab Export is a leading Blood Bag Tube Sealer Manufacturer,and suppliers in India
A blood bag tube sealer closes the PVC tubing of a blood bag by radio-frequency heating, so a segment or a satellite bag can be cut away while both sides stay shut. This bench unit works at 40.68 MHz with a 15 W RF output and makes a seal in about 1.5 seconds. It runs on 230 V AC, 50 Hz and weighs about 5.5 kg.

Practicals with the Tube Sealer
Sealing practice starts on empty bag tubing, so students learn the feel of the jaws before any liquid is involved. They make a row of seals along a length of tube, then squeeze each one, pull it gently and look for an even, flat band.
Next they seal a water-filled practice set. After pressing the main bag in the Plasma Extractor, they place two seals on the satellite tube and cut between them. Weighing both bags on the Blood Bank Scale afterwards shows whether any water leaked past a seal.
Frequently Asked Questions
How do I know a seal is good?
A good seal is a flat band of even width right across the tube, with no bubbles, thin spots or burnt edges. Squeeze the tube on each side of it. No liquid should pass, and the seal should not peel apart when pulled gently.
Why make two or three seals before cutting?
Cutting between two seals leaves both pieces of tubing closed. Labs that need extra safety make a third seal and cut through the middle one, so a sealed band stays on each side of the cut.
What tubing can it seal?
It seals PVC blood bag tubing, because PVC warms up in a radio-frequency field and fuses under the jaws. Polyethylene and silicone tubing do not heat this way and need a different sealing method.
How long does each seal take?
About 1.5 seconds at the 15 W RF output. Keep the tube still in the jaws until the cycle ends, so the PVC has time to fuse right across before you release it.
