• MPN / Catalog Model: Isotemp 9101 (Catalog series 13-874-9101 / Thermo Fisher Scientific NESLAB OEM platform)
• Manufacturer & Line: Fisher Scientific / Isotemp Laboratory Fluid Temperature Control Systems
• Thermal Operating Range: Broad operating span from -10°C to +80°C, providing versatile thermal conditioning for both sub-ambient cooling and elevated temperature loops
• Temperature Stability: Precision PID microprocessor temperature regulation maintaining thermal stability within ±0.1°C to ±0.5°C across the operating envelope
• Cooling & Heating Capacity:
  • Cooling Performance: Nominal cooling capacity of ~700 W to 1000 W at 20°C (powered by a hermetically sealed refrigeration compressor utilizing CFC/HCFC-free refrigerant)
  • Heating Performance: Integrated electric immersion heating element (approx. 1000 W to 1200 W) for rapid thermal ramp rates and high-temperature incubation
• Circulation Pump & Fluid Delivery: High-reliability magnetic drive or positive displacement pump delivering fluid flow rates up to 3.5–4.5 gpm (approx. 13–17 L/min) with discharge pressure up to 40–60 psi, capable of circulating through narrow condenser coils and long-distance external circuits
• Internal Reservoir: High-grade stainless steel fluid reservoir (approx. 4.0 to 8.0 L internal capacity) with a removable access cover for easy cleaning, filling, and routine visual inspection
• Fluid Connections: Standard 1/2-inch or 3/8-inch female NPT / barbed inlet and outlet fluid fittings on the rear panel, accommodating reinforced braided or silicone tubing
• User Interface & Display: Front-mounted digital control panel with dual LED readouts for concurrent display of real-time fluid process temperature and programmed setpoint; includes an integrated mechanical fluid pressure gauge
• Safety & Protection Suite: Low-liquid level sensor with automatic safety shutdown, high-temperature thermal cutout, refrigeration high-pressure cut-off switch, and motor thermal overload protection
• Form Factor & Mobility: Compact, heavy-gauge steel cabinet with chemical-resistant powder-coat finish, mounted on four heavy-duty swivel casters for effortless mobility between lab benches
• Electrical Requirements: Standard 115 VAC, 60 Hz, 1-phase electrical input (standard 15A or 20A grounded plug configuration)
• Primary Application: Heat dissipation and cooling for rotary evaporators (rotovaps), jacketed glass chemical reactors, condenser columns, mass spectrometers (LC-MS / ICP-MS), diffusion pumps, lasers, and automated distillation units
