precision positioning of microsensors
The Unisense MicroProfiling System allows for precise positioning and moving of all Unisense microsensors enabling you to perform microprofiles in an infinite number of different applications.
The MicroProfiling System gives you full benefit of the fine-tipped Unisense microsensors as the MicroProfiling System allows you to move the microsensors through your sample with step sizes down to 0.5 µm.
The MicroProfilling System is a high quality tool for microscale measurements in numerous types of applications e.g. H2S profiles in biofilm, pH gradients in rat brains or oxygen concentrations in sediment samples.
- One system – endless applications
- Correct positioning of microsensors reduces risk of breaking sensors
- Fully automatic system
- For all Unisense microsensors
The MicroProfiling System comes in a manual or motorized setup.
manual microprofiling system
When profiling manually the micromanipulator is operated by hand, a dialog box in SensorTrace Profiling tells you to move the sensor tip to a desired position, which is logged with the sensor signal. The manual MicroProfiling System is an economic and robust tool for completing microprofiles. Precision of the z-axis (depth) is down to 10 µm, while for the x- and y-axes the sensors can be manipulated with 100 µm precision.
motorized microprofiling system
MicroProfiles in 2D or 3D
The Motorized MicroProfiling System will allow you to complete one, two or three dimensional microprofiles automatically. Depth, step size, measuring time and number of replicates for the experiment are managed in SensorTrace Profiling, a software solution that also logs data and allows you to visualize your results while measuring.
The Unisense MicroRespiration microsensors have insignificant analyte consumption and a very low detection limit that allows for detection of minute concentration changes in the chambers. Correct insertion of the microsensor through the capillary is secured by the aluminum guide protecting the microsensor.
