Yes Joe - the point I made was that the 3200 occlusion specification, if the same as the 3100 (3.5Kgf- 4.2Kgf from memory), may be lower than the 3300 occlusion specification.
Unfortunately I haven't looked at a 3200 manual for years so I'm only guessing (perhaps you could tell me what the specification is and how you check compliance with it).
Anyhow what I was getting at is that if we (and others) have had problems with a similar line/syringe setup using the 3300 (200ml/hr stat rate) then problems with a 3200 at 200ml/hr using manufacturers specifications, for the occlusion threshold, are likely.
