The differences hide in the details: a low-surface-area condenser loses vapor to the vacuum pump; a brushed motor drifts off setpoint over time; a cheap seal leaks under vacuum and turns a 4-hour distillation into a 12-hour one; a water-only bath caps you at solvents below 100°C and rules out anything with a higher boiling point.\n    \u003c\/p\u003e\n    \u003cp\u003e\n      The RV131 is spec'd against every one of those failure modes. The \u003cstrong\u003e1500 cm² double-layer vertical condenser\u003c\/strong\u003e maximizes vapor capture — more cooling surface, more recovery, less loss to the pump. The \u003cstrong\u003ebrushless DC motor\u003c\/strong\u003e holds a precise RPM setpoint for life. The \u003cstrong\u003ehigh-elastic graphite-filled PTFE seal with compression spring\u003c\/strong\u003e keeps vacuum integrity through thermal cycling and corrosive vapors. The \u003cstrong\u003e5L water\/oil heating bath to 180°C\u003c\/strong\u003e handles high-boiling-point solvents that a water-only bath can't touch.\n    \u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- ── 3.
