1 Overview
1.1 Features
The Waters Otto SPEcialist Positive Pressure Manifold (PPM) offers advanced positive-pressure
processing of 96-well solid phase extraction (SPE) plates and individual SPE columns in a small
footprint that conserves bench space and fits easily into suitably sized hoods.
Features of the Otto SPEcialist include:
• The innovation and precision ideal for processing 96-well SPE plates and individual SPE
columns up to 6 mL in size.
• The capability to accommodate most commercial supported liquid extraction (SLE) columns
and plates.
• The ability to accommodate both plates and individual columns – only one platform is
required to process either.
• Precision pressure/flow control to accommodate SPE processing needs from very low flow
rates to high flows for sorbent bed drying.
• Pressure programmability – allows for the creation of optimized flow rates across method
steps, as well as within individual steps.
• Virtually unlimited method storage – you can create, store, and retrieve multi-step,
application-specific protocols for sample processing.
• Proprietary Otto-trademarked controllability with automated flow rates, versus flow controllers
and manual regulators – ensures reproducible SPE extractions among multiple users of any
skill level.
• Automatic adjustment of the pressure manifold to the height of the SPE consumables used –
ensures maximum safety and minimum processing time.
• Stepper motor-driven manifold – quieter and more precise than pneumatic cylinder-driven
manifolds.
• Touchscreen controls with Microsoft Windows 10 or above OS – provides a user-friendly
interface that is quick to learn.
