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?

Viscosity is highly temperature-dependent — even 1°C can cause a shift.
ASTM, ISO & in-house SOPs often require precise temp control.
Essential for QC in paints, food, cosmetics, oils, chemicals.

🔍 Brookfield Water Bath Models at a Glance

Model	Control Type	Temp Range	Size / Capacity	Notes
