Brookfield Water Baths: 150 vs 250 vs 550 vs 650 vs Lauda – What’s the Difference?
Mastering Temperature Control – Brookfield Water Baths
“Because viscosity loves consistency — and consistency starts with temperature.”
🌡️ Why You Need a Water Bath?
Even a 1°C change can significantly affect viscosity. Meeting ASTM, ISO, and in-house SOPs often requires precise temperature control. Water baths are essential for QC in paints, food, cosmetics, oils, and chemicals.
🔍 Brookfield Water Bath Models at a Glance
Model | Control Type | Temp Range | Size / Capacity | Notes |
Digital | +5°C to +150°C | Small (6L) | Entry-level; ideal for simple viscosity | |
Digital + Timer | +5°C to +150°C | Medium (13L) | For DVNext/DV2T users | |
Programmable | +5°C to +200°C | Large (18L) | More powerful heating control | |
Advanced Programmable | -20°C to +200°C | Large w/ cooling coil | For thermo-sensitive samples | |
Premium Option | -25°C to +200°C | Varies | German-made, high precision |
🎯 Each model works seamlessly with viscometers using water jackets such as EVJ, ULA, ULA-LG, or small sample adapters.
📦 How to Pick the Right One?
✅ Simple QC or stable lab temp? It is TC-150.
✅ Multiple users or automated cycles? That would be TC-550 or TC-250.
✅ Need chilling or sub-ambient testing? Either TC-650 or Lauda ECO.
