Complete (-OWA) – The complete OWA multiplier is no longer available from S.I.S.. Finnigan MAT retains the patent on this multiplier and chooses not to supply us with the necessary parts.

Old Style (-No Suffix) – The Burle Model 4750G is the complete multiplier used in the early models of the OWA instruments prior to August 1981. A conversion dynode and dropping resistor are not present, (nor are they required). The multiplier is complete and ready for installation in the mass spectrometer.

Burle- The Burle multipliers are the original continuous dynode electron multipliers used by Finnigan MAT in all the OWA instruments.

All models come with a one year prorated warranty.
