Ohaus Mini Hotplate

Item #: 23208-120
Discontinued. See below.

Normal Availability: Discontinued

Product Description

This product was discontinued in 2023. The closest match is the model e-G21HP04C Guardian hotplate which has a 4" x 4" top plate (but a larger footprint, alas).

Ohaus Mini Hotplates (Model HSMNHP4CAL) are rugged, compact units that heat up to 1,000 mL of liquid. The chemical-resistant ceramic top plate has an easy to clean, reflective white surface that measures 4" x 4" (10.2 cm x 10.2 cm).  The housing is constructed of heat-resistant polymer that is cool to the touch and chemical resistant.  A bi-metallic thermostat offers reliable temperature control and the powerful heater reaches maximum temperature, 500 °C, in only minutes.  A built in support rod holder with locking knob at the rear of the unit accepts the optional Support Rod and Clamp Kit (item # 23260).  

This unit can be run in conditions from 5 to 40 °C (41 to 104 °F) and is available in 120 or 230 V.  It comes with a 2 year, industry leading limited warranty on parts and labor.

A detailed description of this model as well as similar hotplates, stirrers, and combination units can be found in our stirrer selection guide.

This model replaces the obsolete Talboys Basic Mini Hotplate (953201) and the Talboys Ergonomic Basic Mini Hotplate (984TA5AHPUS).
