Specifications

Your Thermolyne MIRAK™ 4-place stirrer or
stirring hot plate is a general purpose stirring or
stirring and heating plate designed for laborato-
ry procedures requiring precise control of tem-
perature and/or stirring speed. Each 4-place
MIRAK model includes a digital display for mon-
itoring actual stirring speed, and the stirring hot
plate models have dual displays so temperature
and stirring speed can be monitored simultane-
ously. The 4-place stirring hot plate is capable of
producing accurately controlled temperatures
from 40°C through 540°C on all 208 volt and
240 volt models. 120 volt models have a tem-
perature range of 40°C to 370°C. The tempera-
ture may be controlled at the plate surface by
internal Type K thermocouple sensor, or the
solution temperature may be controlled utilizing
an accessory ungrounded Type K thermocouple
probe. A 6” or 10” general purpose stainless
steel immersion probe or chemical-resistant 7”
solid Teflon
®
immersion probe may be ordered
separately. The stirrer will accurately maintain
stirring speeds from 60 rpm up to 1200 rpm. On
stirring hot plate models, the accessory probe
may also be utilized to display the actual tem-
perature of heat-sensitive solutions during
stirring-only functions. The top plate on the
MIRAK 4-place units is solid ceramic and is suit-
able for use with glass or metal vessels.
Your MIRAK 4-place stirrer or stirring hot plate
may be used for general purpose heating appli-
cations and/or general laboratory mixing of solu-
tions including; sample preparation, heating
reagents, melting paraffin, warming resinous
chemicals, content analysis, solvent evapora-
tions, digestions, media preparation and sterili-
zation, titrations, sand baths and microscale
chemistry applications.
