Sealing electrode plate SC*W017 TDCD WAFER

Technical characteristics


Product Name:

Sealing electrode plate SC*W017 TDCD WAFER

Product Type:

Electrode (wafer plate) for thermal sealing of mains and tubes of blood containers

1. Purpose

The electrode plate is intended for use in devices for thermal sealing of tubes and lines of blood containers. It provides reliable and hermetic sealing of plastic tubes after procedures for collecting, processing and separating blood components.


2. Scope of application

  • blood services;
  • transfusion departments;
  • blood collection and processing centers;
  • laboratories and production sites using blood containers with PVC pipes.

3. Compatibility

  • designed for sealing devices (tube sealer) operating on the principle of thermo- and electric welding;
  • compatible with mains and tubes of medical PVC blood containers;
  • It is used in systems using TDCD (Thermal Direct Conduction Device) technology.

4. Construction

  • type of execution: flat plate (wafer);
  • working surface: heated, smooth, with uniform temperature distribution;
  • Shape: rectangular / technological (according to the equipment model);
  • Installation: it is installed in the holder of the sealing device.

5. Materials

  • Working surface: heat-resistant metal alloy with high thermal conductivity;
  • Base: wear-resistant heat-resistant material;
  • the materials are resistant to high temperatures and multiple heating/cooling cycles.

6. Technical parameters

  • Heating type: electric, contact
  • Operating temperature: up to ≈ 250-300 °C
  • Operating mode: cyclic
  • Tube assignment:
  • PVC lines of blood containers
  • Outer diameter of tubes: 3, 3.0 – 6.5mm
  • Sealing type: full hermetic sealing with simultaneous separation of the tube

7. Operational characteristics

  • provides a strong, uniform and sealed weld;
  • eliminates blood leakage and impaired sterility;
  • stable operation during intensive operation;
  • it is designed for a long service life in compliance with the rules of use.

8. Sterility

  • The product is not sterile;
  • does not come into direct contact with blood;
  • sterility is ensured by hermetically sealing the main line.

9. Operating conditions

  • Use only in compatible hardware;
  • operation by trained medical or technical personnel;
  • it is forbidden to use in the presence of mechanical damage to the work surface.

10. Storage conditions

  • Storage temperature: from +5 °C to +40 °C;
  • store in a dry place, protected from moisture and dust.;
  • avoid mechanical shocks and contamination of the work surface.

11. Classification

  • a component part for medical equipment;
  • It is not an independent medical device.;
  • consumable / wearable piece of equipment.
