1E-8 torr would be a rough estimate at 800 km. It depends on where you are in the orbit, the solar activity, etc.etc.etc. If you want better vacuums, you use a "wake shield", a surface in "front" of your experiment (i.e. in the direction of flight, which essentially blocks any atoms/molecules/particles from hitting your experimental area.
