Invasive laser Doppler probes intended for blood perfusion measurements on intact mucosal membranes. Probes can be fixed by such methods as micromanipulators, laboratory stands, and biopsy channels of an endoscope (measurements in the trachea, stomach, intestine or colon).

A selection of probes is presented below. Specific dimensions can be viewed in the laser Doppler probe brochure.

Please contact us if you can not find a suitable probe for your particular application.

Note: The 300-series probes are designed to fit the PeriFlux PF 2B and PF 3. The 400-series probes are designed for the PeriFlux System 4000 and PeriFlux System 5000.

probe 410

PROBE 410 (310) Angled Stainless Steel Probe

The support is designed to fit in a micromanipulator or laboratory stand for exact positioning. Convenient for measurements on animal organs or in body cavities. Similar to PROBE 403 but the angled tip of the probe makes tissues such as nasal and oral mucosa more easily accessible.
Fibre separation: 0.25 mm.

 probe 416

PROBE 416 (316) Dental Probe

Designed for measurements on teeth. For this application, the probe is fixed by drilling a hole in a "splint" about 1.5 mm from the gingiva.
See also PROBE 407 together with PH 07-6.
Fibre separation: 0.25 mm.
