Hooded SPS: solvent purification for labs with mandated hood installation.
Use the Hooded configuration when facility or EHS requirements dictate that the purification system live inside a fume hood. PPT positions it as a way to meet that constraint without driving a larger HVAC redesign.
This is a facility-driven configuration.
The reason to choose Hooded is not simply preference; it is that your lab, EHS team, or facility standard requires the system to be located in a hood and the equipment must be configured around that envelope.
Mandated hood placement
PPT specifically positions this format for required hood installations.
Existing facility constraint
Useful when the project needs to work with the hood rather than redesign the room around another SPS format.
Workflow still matters
Solvent count, dispensing access, flask handling, column service, and glovebox integration still need review.
Define the configuration around your installation.
Published format guidance is a starting point. Confirm the selected arrangement, utilities and access with PPT.
Hooded SPS
Published configuration
- Solvent count
- Project-specific
- Dimensions / installation
- Configured to fume-hood envelope
Final dimensions, column arrangement, utilities, and installation details depend on the selected configuration and site conditions.
Purify your solvent, then protect it during collection.
Your solvent supply feeds purification columns selected for the chemistry. Vacuum-sealed flask connections and an argon blanket protect collected solvent from re-exposure. Confirm solvent-specific media and connection materials with PPT.
Connect your solvent supply
Review your supplier kegs, solvent grades and container connections.
Remove water and oxygen
Route your solvent through the selected purification columns.
Collect under argon
Use protected flask connections for collection and transfer.
Connections and integration
Review your flask sizes, glovebox interfaces, vacuum-pump controls and keg connections with PPT. Your collection and transfer requirements determine the hardware to include.
Space and service access
Leave room to reach valves, collect solvent and remove columns for service. Account for the additional solvent lines your research group may need later.

The details that change the recommendation.
Keep the selection process short and useful. These are the inputs that actually affect which SPS format works best.
- Hood dimensions
- EHS/facility requirement
- Solvent count
- Sash/access
- Argon/vacuum routing
- Glovebox integration
- Column/flask service access
Plan the parts that keep the system usable and serviceable.
PPT supports replacement columns, column refill service, flasks and connections, vacuum-pump controls, glovebox integration, stainless kegs, and other system components.
Replacement columns
Factory-activated replacement columns let labs swap columns without waiting for the existing set to be refilled.
Column refill service
A lower-cost option that requires removing and shipping the existing columns to PPT, which creates lab downtime.
Flasks & connections
PPT supplies vacuum-sealed flask and connection hardware for day-to-day dispensing.
Glovebox integration
Direct-connect integration can be planned around the number of solvent lines and your lab workflow.
Design to the actual hood envelope.
Bring hood dimensions, photographs and your facility requirements.

Hood and sash geometry
Confirm the interior envelope, sash opening, collection position and access for column removal.
Solvents and workflow
Identify your solvent list, container arrangement and any glovebox connections before setting the column layout.
Utilities and ventilation
Coordinate argon, vacuum, utility routing and ventilation requirements with your site team.
Facility and EHS review
Hood placement alone does not establish safety compliance. Review the selected system and operating workflow with your facility and EHS teams.
Installation, operation and ongoing support.
Installation & training
Remote resources and video support are available; on-site installation can be quoted separately.
Troubleshooting
PPT maintains training videos, manuals, and procedures for common SPS operating and maintenance tasks.
Column lifecycle
PPT states column capacity at roughly 600–800 liters or about five years, with actual life depending on solvent use and operating conditions.
OEM parts
Replacement columns, flasks, controls, kegs, connections, and other supported components are available through PPT.
Additional configuration considerations
Most avoidable problems come from sizing only for today's solvent list, underestimating service access, or leaving integration and EHS review until after equipment is selected.
- Selecting the system before measuring the actual hood envelope.
- Missing EHS review until fabrication is complete.
- Creating poor service access inside the hood.
- Assuming hood placement alone solves all safety or workflow issues.
