Matched Microchannel Plate Set
Standard Resistance Microchannel Plate
for Detectors
Maximize Your Instrument’s
Performance With Our
Optimum Five Micron Pore
Microchannel Plate
The Model MCP3301 is K and M
Electronic’s standard resistance
Microchannel Plate (MCP) for Time-ofFlight Mass Spectrometry (TOF/MS).
These optimum quality plates have precise
five-micron pores, creating extremely high
channel density that offers higher sensitivity
and resolution than plates with
conventional 10-micron pores.
