Thermostatic Magnetic Stirring Bath - Water/Oil Bath with Stirrer - 3 L, 5 L - RT to 220°C

The Master Science Thermostatic Magnetic Stirring Bath is a dual-use water or oil bath with built-in magnetic stirring. The stirrer moves the bath liquid and, through it, the sample in the flask, so both are heated evenly. Two sizes hold flasks up to 3 L or 5 L.

The bath liner is high-borosilicate glass with a viewing window and a stainless steel base, protected by a heat-resistant outer shell. Heating runs from ambient to 220°C with ±1°C control, stirring from 100 to 1500 rpm with reversible direction, and an LCD shows speed, time and temperature on the Master Science Thermostatic Magnetic Stirring Bath.

Key Benefits

• Uniform heating: Stirring the bath liquid also stirs the sample for even temperature.
• Water or oil: Dual-use bath up to 220°C.
• Visible reaction: Glass liner with window lets you watch the flask.
• Sample protection: Heating stops at the end of the timer while stirring continues.

Problems the Master Science Thermostatic Magnetic Stirring Bath Solves

Hot plates with a separate bath heat unevenly and are harder to control. The Master Science Thermostatic Magnetic Stirring Bath helps with:

• Uneven sample heating: Bath and sample are stirred together.
• Running a bath dry: Boil-dry protection switches off heating.
• Accidental burns: A protective shell and HOT warning reduce risk.
• Overheating at end of run: Heating stops when the timer ends while stirring continues.
