What are the advantages of a glass ceramic hotplate?

Glass ceramic plates offer excellent chemical resistance, are easy to clean, and typically have cooler edges to reduce burn risk during operation.

Can this unit be used for unattended operation?

While units of this type often have safety features like overheat protection, continuous unattended operation should be assessed based on specific application risks and laboratory safety protocols.

What is the typical footprint of a hotplate stirrer like this?

Hotplate stirrers in this category are generally compact, designed to fit on a standard laboratory bench.

How do I control the heating and stirring functions?

Analogue models typically feature separate rotary controls for adjusting heating power/temperature and stirring speed.

Is this model still supported by the manufacturer?

The CB162 is an obsolete model; buyers should consider the availability of spare parts and service from third-party providers. Successor models are available for new purchases.

Overview: Stuart CB162 Hotplate Stirrer

The Stuart CB162 is an analogue hotplate stirrer combining heating and magnetic stirring capabilities. It has traditionally been used in lab settings for tasks requiring both uniform heating and effective mixing.

Key specifications include:

Plate material: Glass ceramic — highly resistant to chemicals and heat, easy to clean, with cooler edges to reduce burn risk.

Heating power: Approximately 500 W, capable of reaching a maximum plate temperature of about 450 °C.

Stirring speed: Variable from ~100 to 1,500 rpm, using strong magnetic coupling.

Capacity: Effective for stirring up to around 15 litres.

Safety features:

A flashing "Hot" warning light that stays on if the plate temperature exceeds 50 °C — even when turned off or unplugged.

Spill‑proof design and an independent safety circuit to prevent overheating.

Product Status & Successors

The CB162 model is now obsolete.

It has been officially replaced by the Undergrad UC152, a newer analogue hotplate stirrer with similar features.

The SB162, a similar model but with an aluminium‑silicon alloy plate, was replaced by US152
