Choosing a Temperature Probe
- Flexible Teflon microprobes are used for implantation in tissue, in spectrophotometer cuvettes, rectally in neonatal mice, in water baths, PCR thermal cyclers, etc.
- Animal rectal temperatures during surgical procedures and pyrogen testing.
- Skin temperature measurement during exercise physiology studies.
When precise temperature measurements are required, WPI can provide you with a very accurate monitor and thermocouple microprobes. WPI monitors have both resolution and accuracy of 0.1°C in the 0-50°C range and are traceable to NIST standards, whereas, other competitive electronic thermometers have an accuracy that is usually to 0.5°C or worse. Furthermore, all our type T clinical probes are guaranteed accurate to 0.1°C, due to our stringent wire standards. These are five times more accurate than competitive probes made with regular “Special Limits” wire.
Probe Sterilization Methods:
The needle microprobes and animal rectal probes are all designed to withstand sterilization by ETO gas and gluteraldehyde solution. Our flexible implantable microprobes are both ETO gas sterilizable and autoclavable.
Fast-response needle probes for instant readings in tissue, semisolids, liquids, very small specimens, powders and materials. Needle tip is sealed to ensure only stainless steel contacts specimen.
