The new Electronic Von Frey unit EVF3 is easy to use and allows you to quickly find the sensitivity threshold in rodents.
This value is measured in only ONE test, and is highly repetitive. With the same analgesia equipment you will be able to carry on animal and human studies (clinical studies: only for research protocols while the agreement for Medical CE mark is in process). The resolution of the screen is 0,1 gram.
Sensibility thresold result is displayed on a large backlighted screen and you will not get any temperature or hygrometry drift as that was the case with the filaments. The Electronic Von Frey EVF3 is supplied with a COFRAC related calibration certificate (ISO 9000), and an EMC conformity agreement.
Main functionalities:
• Large backlighted LCD screen displaying current and peak value
• Statistical functions: average value and standard deviation are computed for each subject
• Stand-alone instrument: internal memory allows the storing of up to 100 values, which may be transfered to a PC using our optional software
A few options for easier operations:
• A patient switch allows to freeze the displayed value when
the threshold is reached
• An RS232 interface allows to transfer the displayed value
on to a computer
• Our RSIC software allows to write directly on EXCEL7 the
value measured (PC with Windows 98 or XP) thus you avoid
transcription errors, and get instant report
Supplied with:
• 1 calibration certificate (yearly re-calibration carried out by BIOSEB)
• 1 EMC agreement
• 10 disposable plastic tips
• 1 spring tip for thresholds between 0 and 10 gramms
• Footswitch to reset the display to zero
• Carrying case for transport
