easyTEL+ RP is a reusable telemeter that can acquire up to 4 biopotentials and activity from conscious, freely moving subjects 200g and upwards.
This cost-effective option can be customizable for either a non-invasive or implantable design.
In rodents (formerly rodentPACK), easyTEL+ RP is particularly recommended for neurological applications, safety pharmacology and toxicology studies and drug development. In an interview, Dr. Poulsen from the Neurosurgery Department, in the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo, said “The combination of EEG, acceleration, and video is a huge upside to the emka system.”
In large animals (formerly eegPACK), easyTEL+ RP is particularly recommended for prodromal screening and for acute and chronic assessments to evaluate seizure potential, when the period of risk following the administration of a compound is unknown.
The whole system is compact, as a single receiver can communicate with up to 4 transmitters. Receivers are powered and transmit data through a single Ethernet cable. easyTEL+ RP removable telemeters are attached to a head connector or housed in a jacket (rodent) or a cap (large animals) during recording sessions.
This system can be used in combination with easyTEL+ M1 implants for rats or easyTEL+ for large animals, to monitor blood pressure (arterial and LVP) as well as temperature.
Adding an easySYNC device to the basic system allows to track and analyze the behavior, movement, and activity of an animal in Noldus EthoVision software while synchronizing physiological data from easyTEL+ RP telemetry system. Learn more about the easySYNC.
Combining easyTEL+RP with whole body plethysmography offers researchers a comprehensive understanding of the intricate mechanisms linking respiratory, cardiovascular, and neurological functions. The vivoFlow+ plethysmograph respiratory parameters can be acquired simultaneously with cardiovascular and neurological data from the easyTEL+ RP via the easyDAC box. All signals acquired by easyDAC are fully synchronized and simultaneously recorded in IOX2 software.
| Specifications | Value | Units | Continuous recording | 150 | h |

| Max. number of subjects per room | 32 | - |
| Max. number of physiological signals per subject | 8 | - |
| Transmitters weight | 5.2 | g |
| Transmission range | 5 | m |
After an acclimation of under 24 hours, rats ignore the device. They do not try to touch it nor do they try to rub it against the cage walls.
Yes, it is possible, on special request.
rodentPACK includes 4 biopotential channels. Each channel can be configurated as a bipolar or unipolar biopotentials. Model of electrodes, length, type of final connection (screw…) can be configurated as well.
See “How can I get a “ready to use” head connector for rodentPACK”.
easyTEL+RP telemeter can amplify and transmit up to 8 signals: 4 biopoentials and acceleration (3-axis + 1 global acceleration).
When you order an easyTEL+RP, we ask you to fill a specific form where you can specify your settings for each biopotential input: Type of signal (ECG, EMG, EOG, cortical EEG, Hippocampal EEG), input range, sample frequency, resolution, connector pins mapping.
easyTEL+RP telemeter runs on two zinc-air P13 batteries (1.45V), single-use.
Zinc-air batteries need to stay in contact with the ambient air (out of their packing, with the plastic protection removed) during one minute, before being installed in their support.
Failure to wait at least one minute will result in permanent damage to the battery and to dramatically reduced battery life.
The positive face is on the top for both batteries. Do not insert the batteries in the wrong position as it may damage the transmitter.
Do not use batteries that would be almost empty.
When fully discharged, batteries swell then oxidize, which damage the batteries holder.
The head-mounted option provides:
However, this option has 2 limitations:
easyTEL+RP telemeters are using the same technology as our implantable easyTEL+ telemetry. Therefore, it is possible to perform acquisition of easyTEL+ implants and reusable telemeters using the same acquisition platform, either combined and independently.
