Thermo Scientific Insulating Foam Ring Fits Model G

Thermo Scientific Savant Vapor Trap Cover Insulating Foam Ring (145-6012-00)

The Thermo Scientific 145-6012-00 (alternatively cataloged under Fisher Scientific as Part Number NC0980083) is an OEM replacement thermal component engineered for integrated vacuum concentrators and cold vapor traps. Constructed from a high-density, closed-cell insulation composite, this foam ring is custom-molded to fit the cover assembly of Model G glass condensation flasks (including GCF400 setups). By providing a strict thermal boundary layer, it prevents ambient heat exchange, accelerates vapor condensation cycles, and eliminates condensation sweating on external instrument housings during high-vacuum evaporative protocols.

Technical Performance & Design

• Thermal Boundary Optimization: Formulated from structural closed-cell insulation foam that isolates cold trap chambers from ambient room heat, maximizing the deposition efficiency of volatile solvents on cooling surfaces.
• Anti-Sweat Condensation Control: Prevents moisture from air humidity from liquefying on outer chamber components, shielding nearby electronics and vacuum manifolds from water pooling or chemical-mist contact.
• Snug-Fit Geometric Calibration: Designed specifically to slip over and seal against the perimeter of Model G collection lids, ensuring a zero-clearance friction seal without using volatile adhesive backings.
• Chemical-Vapor Shielding: The robust poly-foam matrix resists surface degradation when exposed to common evaporated lab solvents, weak organic acid mists, and standard chemical cleaners.

Key Benefits & Applications

• SpeedVac Run Maintenance: Maintains the extreme low-temperature differentials necessary to condense and trap solvents rapidly, optimizing sample dryness times across concentration workflows.
• Protective Pump Shielding: Assists in maximizing the efficiency of the cold barrier to trap volatile vapors completely, preventing aggressive chemicals from migrating past the flask and degrading internal mechanical pump oil.
• Direct OEM Component Fitment: Serves as a direct drop-in part for worn, torn, or chemically degraded insulation covers, returning vacuum concentrator stations to factory-validated technical performance specifications.
• Tool-Free Bench Installation: The pliable structure slips cleanly over the glass trap cover assembly manually, facilitating rapid maintenance cycles during scheduled lab equipment inspections.

Part number 145-6012-00 represents the insulating ring specifically calibrated for Model G glass condensation lids. For smaller or alternative glass traps (such as the 4-liter GIT400 system components), alternative foam variants like the GTC400 assembly must be specified independently.
