The Trovan difference

The Trovan difference

If all microchips sold in the UK have to be ISO compliant, doesn't that mean that all microchips are the same?

The ISO standards only govern how manufacturers must encode the microchips, and how the microchips must respond when scanned with an appropriate scanner. The ISO standards are not a mark of build or material quality, and do not even guarantee code uniqueness - all of these remain the responsibility of the manufacturer.

So although all microchips available in the UK must conform to the ISO standards, there are still wide differences in the build quality and reliability of the different microchips available on the UK market. Understanding how each microchip may differ is crucial for implanters when deciding which supplier to use.

Trovan microchips are well known for their high quality and reliability - from the state of the art facilities, laser sealing and programming to a patented design that reduces the number of potential failure points, Trovan have taken animal microchips beyond the next level!

Proven Longevity and Reliability - In recent times there has been an increase in the number of low cost microchips arriving on the market. These microchips are generally manufactured outside Europe, have not been in use for very long, and, because of their use of low cost and inferior components, plus a more manual assembly process, they are often a poorer quality product. As a result they have a higher risk of problems such as low reliability, poor performance and even breakages. Trovan microchips are manufactured in Europe to the highest quality under six-sigma standards and are fully ISO 11784/11785 compliant.

900 prefix microchips are “shared manufacturer” microchips, and, compared to the long time proven microchip manufacturers like Trovan, have only been approved and manufactured since September 1st, 2004. Some have only entered the market very recently and are yet to be proven for reliability in the long term. They tend to be low volume suppliers, since once a manufacturer has made a signficant number of microchips they are 'graduated' to a non-shared manufacturer code. Trovan microchips are used worldwide in zoos because they are well known for their reliability when used in long-lived species.

Direct bonding technology - The patented design of Trovan microchips drastically reduces the number of connections in the microchip, and it is connections where potential failures occur! The use of gold connectors reduces risks further still and six-sigma standards mean Trovan microchips are extremely reliable. The potential failure points of Trovan microchips are reduced to a third when compared to most competitors.

Laser Programmed Integrated Circuits - Trovan microchips contain laser programmed integrated circuits (IC’s). Most competing products use electronically programmed circuits called EEPROMs, (also written E2PROM - which stands for Electrically Erasable Programmable Read-Only Memory), that can be negatively and permanently damaged by electromagnetic interference. These electronically programmed IC’s can often only be guaranteed for a limited number of read cycles and for a maximum of 10 years. Many electronically programmed IC's have the potential for reprogramming ie. changing their identity. Some are actually manufactured as blanks to be written, others may not be locked so that they can be re-written.

A major concern is that some current  E2PROM microchips could be wiped by MRI operating at a high Tesla - now that this is available as a major diagnostic technique in dogs and cats the animals may have their  E2PROM microchips rendered useless in these cases. A good reason for using laser programmed microchips produced by Trovan.

Flexibility  – Our Trovan microchips can be supplied in both a two part system consisting of a needle and re-useable implant tool, or a convenient single use all-in-one format. We can also supply them in both the regular and mini size. Full flexibility for implanters to choose a system based on their preference.

Bioglass encapsulation - Trovan don't use anti-migration coatings which might cause problems, they encase the ferrite core and internal components in bioglass to ensure acceptability by the tissues. Non-bioglass capsules may contain aluminium and other potentially toxic materials. Bioglass is also the best material to provide full protection from bodily fluids and moisture.

This produces a microchip with outstanding reliability and longevity - obviously important everywhere, but especially vital for long living species such as birds and reptiles and many other zoo animals. Trovan microchips are in use in wild animals for conservation projects literally all over the world.
