VivoTag® RFID Transponder Glass Tubes

Product Description

SCHOTT VivoTag® transponder glass tubes are used to reliably encapsulate and protect sensitive RFID transponder devices. The main application areas include implantable transponders and bolus transponders for pet and livestock identification and tracking.  

Biocompatible glass tubes


SCHOTT VivoTag® transponder glass (also known as 8625) has been successfully used in animal identification for decades, making it the most proven material for implantable RFID applications. As an inert material with consistent chemical stability inside the body, the glass tube enables the required long-term functionality of the electronic components.

SCHOTT’s transponder glass 8625 was specially formulated and successfully tested to show excellent biocompatibility in animal applications (cytotoxicity, hemo-compatibility).


Small sizes, easy to process

SCHOTT VivoTag® transponder glasses are precision-cut glass vials available in customizable dimensions and lengths. The standard outside diameter of such vials ranges from as small as 1 mm up to 4 mm. Customers can choose the size to achieve an optimal balance between transponder dimensions and required RFID reading distance.

Transponder glasses typically have one sealed and one fire-polished end. Due to the high iron content of the glass, it can be sealed using a variety of light sources (e.g. Nd-Yag lasers).
SCHOTT’s focus on high precision and stable batch-to-batch quality enables our customers to benefit from optimal processability in production.


RFID tracking and identification

Apart from animal identification, VivoTag® glass tubes are also used in technical areas, such as RFID freight tracking and automotive applications, where the RFID transponders need to be reliably protected against harsh environments.



 

Advantages

SCHOTT VivoTag® 8625 transponder glass offers the following advantages:
 
  • Proven track record: SCHOTT‘s 8625 VivoTag® transponder glass has been successfully used in animal identification for decades.
  • Excellent biocompatibility for animal applications demonstrated in various studies.
  • Ease of use in processing and end-use applications thanks to high precision and accuracy in terms of glass composition and dimensional tolerances.
  • Small sizes available down to 1.25 mm outer diameter.
  • Fast and flexible sampling for standard as well as custom-made solutions.
     

Applications

Our customers use SCHOTT VivoTag® transponder glass for the hermetic encapsulation of RFID transponder devices. End-use applications are found in a variety of fields:
 
  • Livestock identification and tracking records the origin and supports safety processes for meat.
  • Biocompatible RFID transponders are subcutaneously injected or implanted with a syringe for pet identification.
  • Logistics support for freight and automotive industries.
RFID stands for "Radio Frequency Identification". RFID transponders consist of a semiconductor chip and an antenna. Using radio waves emitted from a reading unit, specific information can be stored on and read from the chip. The technology functions completely wirelessly: depending on the configuration, the distance between the reading unit and the RFID transponder ranges from several centimeters to as much as one meter. No battery is needed since the necessary energy for sending and receiving is entirely supplied by radio waves from the reading unit.

 

Technical Details

Technology

The fabrication of glass tubes is one of SCHOTT's key competencies.

All high-precision cutting and sealing equipment has been developed in-house. SCHOTT VivoTag® transponder glass vials have one sealed and one fire-polished end. The fire-polishing of the open end prevents chipping during transportation and eliminates the need for further processing by protecting the electrical unit from damage during insertion into the glass vial.
