Flexible Implantable Probes (Type T Thermocouple)

Flexible Implantable Probes (Type T Thermocouple)

Flexible Implantable Microprobes are implantable in semi-solids and tissue with needle (supplied). Also for immersion in various solutions and rectal temperatures of small animals. Totally sheathed in chemical resistant Teflon. Max Temp. 150°C. Isolated. 

Features

  • Type T thermocouple
  • Implantable in semi-solids and tissue
  • Small with fast response time
  • Isolated
  • Temperature range -100°C to 150°C
  • ± 0.1°C accuracy over physiological range
  • Suitable for sterilization by autoclave, ETO gas, Gluteraldehyde or Isoprophyl Alcohol

Options

  • 23ga needile diameter 0.025" (0.63mm)
  • 26ga needle diameter 0.018" (0.46mm)
  • 29ga needle diameter 0.013" (0.33mm)

The microprobe can be inserted through the supplied needle.

All flexible implantable microprobes are ecapsulated in Teflon apart from IT-1E which has the sensor bead exposed.

Time constant is defined as the time  required to reach 63% of final temperature  in liquid.  An accurate reading is obtained  when the reading stops changing, typically  5-10 time constants.

Maximum Temperature refers to intermit tent use of a probe. When probe is used for continuous measurements, maximum temperature should bereduced by 25%.

Applications

Flexible Teflon microprobes are used for implantation in tissue, in spectrophotometer cuvettes, rectally in neonatal mice, in water baths, PCR thermal cyclers, etc. Also, measure animal rectal temperatures during surgical procedures and pyrogen testing or skin temperature measurement during exercise physiology studies.

Probe Sterilization Methods

The flexible implantable microprobes and animal rectal probes are all designed to withstand sterilization by ETO gas and gluteraldehyde solution.
