Pricing & Ordering Info


Designed especially for stirring the contents of round-bottom flasks that are being heated with a flask heater such as a THERMOWELL or other heating mantle, ECONOSTIR will also efficiently stir liquid systems in beakers, flat bottom flasks, etc.

  • Large size top, 6.0" x 6.0" will easily support a 500-mL THERMOWELL, or a 2-liter beaker.  The aluminum top has a heavy epoxy coating which will resist spills from standard lab chemicals and solvents.
  • Positive impeller-induced ventilation draws cool air through bottom vents and forces it out through the corner openings underneath the top, effectively cooling the top.  This unique design will keep the magnet and motor cool despite great heat stresses from the operating flask heater.
  • The magnet is a 30-gram Alnico V bar magnet, powerful enough to develop a 0.5 inch surface vortex with unheated, undiluted glycol antifreeze in a half-filled 500 mL r.b. flask that is being held by a THERMOWELL flask heater.
  • ECONOSTIR is equipped with a pilot lamp, a 36" 3-wire cord, polyurethane feet, with a power consumption of 45 watts, 120 volts, 60 Hz.  It is 6.0" x 6.0" x 3.5" high and weighs 3.2 pounds.  Stirring bar sizes recommended for round-bottom flasks are Teflon coated straight bars 3/8" diameter 1.25" to 1.5" for 500- and 1000-mL flasks, and 5/16" diam. by 5/8" to 7/8" long for 50- and 100-mL flasks.
