Evom™ Manual Features; Evom™ Manual Benefits - WPI EVOM Manual Instruction Manual

a low AC current that avoids electrode metal deposits and adverse effects on tissues
which can otherwise be caused by higher DC currents. The EVOM™ Manual uses
low current and voltages and is designed for non-destructive testing for epithelial
monolayer confluence in cell cultures. In addition, resistance readings are unaffected
by membrane capacitance or membrane voltage. The accuracy and repeatability of the
EVOM™ Manual system makes this instrument ideal for permeability, PD and other
detailed membrane studies.
EVOM™ Manual Features
• Low noise design offers greater resolution and accuracy
• Automatic 20X sample averaging improves accuracy and stability
• Adjustable fixed measurement currents (2, 4 or 10 μA)
• Resistance auto ranging from 1 Ω to 100,000 Ω or with three fixed current ranges
• Reliable low current, low voltage design prevents metal ion transport
• Fast resistance stabilization on low levels under 200 Ω with resolution to 0.1 Ω
• Ergonomic tilt stand for low glare operation
• Graphical display of popular plates (6, 12, 24, 96) for trend analysis
• The display shows the most recent set of parameters
• Automatic plate indexing operation with or without control well subtraction for
resistance and potential difference (PD) measurements
• Continuous data logging via USB (PC, Mac, Linux)
• Saves date stamped data to a spreadsheet readable file on a USB drive
• Upgradable firmware
EVOM™ Manual Benefits
Eliminates errors and reduces experimental processing time
Auto data logging eliminates the need to track data by hand
The small footprint allows more bench space
Easy calibration and verification
Footswitch for hands-free recording
Prevent data loss with auto save and data recovery when battery
is low
TEER is easily computed by applying a unit area formula to the
resistance
