Tektronix or similar High gain low-noise pre-amplifier

We need to buy a pre-amplifier for the lab here. It's to be used to
amplify a detector signal.

We need to be able to amplify a signal in the low mV range up to the
high mV range.

Are there any models that any of you guys could suggest?
I suppose the query will get refined as the posts add up and I can
clarify more the exact specs needed from my prof.

Ahhh... bandwidth? impedance levels? accuracy?

Hey man,
Turns out we just built an pre-amp from scratch.
The problem was, our oscilloscope had a limited offset capacity (2V)
and we needed at least that much to get to our data - drifts due to
heat you know. So we just built one - its an inverting amp with the
output sitting on a another unity gain amp with a rheostat.
