Technology in Stargate - Tok'ra Technology

Tok'ra Technology

The Tok'ra are an offshoot of the Goa'uld and thus have access to many of their technologies, such as force-fields, memory devices and transphase eradication rods. Tok'ra forces rely on zat'n'ktels, as they lack the naqahdah necessary to build staff weapons. The Tok'ra often assist the SGC in developing new technologies, and they have provided many pieces of their technology to Stargate Command when required. Tok'ra one-way force-fields are installed in the SGC's isolation rooms. Prominent Tok'ra technologies include:

• Crystal tunnel Used by the Tok'ra to quickly build new bases, these tunnels grow underground automatically from a small seed crystal into predetermined configurations, manufacturing oxygen in the process to create a livable environment. They can also be collapsed rapidly should the Tok'ra need to evacuate. They are used to facilitate a Langaran drilling machine on a mission to stop the underground spread of naqahdriah.
• Goa'uld tracking network An encoded subspace network that receives signals from tracking devices on over a hundred Ha'taks, placed by Tok'ra operatives over a number of years. Jacob/Selmak provides a receiver to this network to the SGC in order to monitor the war between the Goa'uld and the Replicators.
• Kull disruptor A weapon based on an Ancient healing device, that can neutralize Kull Warriors.
• Radioactive isotope When injected, this isotope conceals the user from sensors for eight hours. It is used by Daniel Jackson and Jonas Quinn to infiltrate Anubis' mothership.
• Re'ol chemical A memory-altering substance derived from the natural secretions of the Re'ol species, which allows a subject to fool another into trusting them. It is used by Daniel Jackson to infiltrate a summit of the System Lords, and by Cameron Mitchell to infiltrate the Lucian Alliance
• Symbiote extractor Apparatus used to extract a symbiote from a host. Ba'al's clone was the first to be shown having been removed from its human host. Other symbiotes have been removed from their host by the Tok'Ra before this, whether this device or other means were used to do this is unknown.
• Symbiote poison An aerosol toxin deadly to Goa'uld symbiotes, that is highly potent even in minute quantities. It is originally developed to assassinate the System Lords, but is instead used to wipe out Anubis' army on Revanna. The Trust later gains access to the poison and uses it to attack Goa'uld worlds in "Endgame", killing millions of Jaffa in the process.
• Tretonin A drug extracted from Goa'uld symbiotes, introduced in "Cure" as the creation of the Pangaran civilization, using the spawn of the Tok'ra Queen Egeria. The drug reproduces the symbiote's healing powers, allowing perfect health and extended life, while also suppressing the user's natural immune system as the symbiote does. The Tok'ra eventually develop a synthetic version of tretonin, which is first tested on the Jaffa in "Birthright" and eventually becomes widespread amongst the Jaffa, freeing them from their dependence on the Goa'uld. Tretonin is ineffective in a small number of Jaffa.
• Za'tarc detector A device invented by Anise, meant to work in conjunction with a memory device to search for false memories that would indicate that a person has been brainwashed into a za'tarc assassin. It works by comparing the subject's conscious and subconscious mind. However, it can give a false positive if the subject is subconsciously concealing something else, such as in the case of Jack O'Neill and his attraction to Samantha Carter.
