These include automatic over- and under-temperature alarms, door monitoring, programmable operation, and the 140°C high-temperature decontamination cycle.\u003c\/p\u003e\n\u003ch4\u003eIs the Heratherm IMH750-S a CO₂ incubator?\u003c\/h4\u003e\n\u003cp\u003eNo. The IMH750-S is a \u003cstrong\u003emicrobiological temperature incubator\u003c\/strong\u003e, not a CO₂ incubator. It controls temperature but does not provide regulated CO₂, humidity, or oxygen control.

Although its model name includes “750,” Thermo's published specifications list the actual usable capacity as 702 L.\u003c\/p\u003e\n\u003ch4\u003eWhat is the difference between the Heratherm IMH750-S and IGS750?\u003c\/h4\u003e\n\u003cp\u003eThe \u003cstrong\u003eIGS750 is a General Protocol gravity-convection incubator\u003c\/strong\u003e, while the \u003cstrong\u003eIMH750-S is an Advanced Protocol Security mechanical-convection model\u003c\/strong\u003e. The IMH750-S also offers a higher maximum temperature of 105°C, enhanced alarm and timer capabilities, and the 140°C decontamination cycle.\u003c\/p\u003e\n\u003ch4\u003eDoes the IMH750-S have a high-temperature decontamination cycle?\u003c\/h4\u003e\n\u003cp\u003eYes. The IMH750-S incorporates Thermo's \u003cstrong\u003e140°C decontamination routine\u003c\/strong\u003e, designed to reduce microorganisms within the chamber and on internal fittings during a dedicated high-temperature cycle.\u003c\/p\u003e\n\u003ch4\u003eCan the IMH750-S be used at 37°C for microbiology?\u003c\/h4\u003e\n\u003cp\u003eYes. The incubator is well suited for \u003cstrong\u003eroutine microbiological incubation at 37°C\u003c\/strong\u003e as well as other temperatures within its ambient +5°C to 105°C operating range. Mechanical convection helps maintain uniform chamber conditions across large sample loads.\u003c\/p\u003e\n\u003ch4\u003eCan equipment be operated inside the Heratherm IMH750-S?\u003c\/h4\u003e\n\u003cp\u003eThe incubator incorporates an \u003cstrong\u003eaccess port for independent sensors and compatible laboratory equipment\u003c\/strong\u003e. Depending on the application, equipment such as a stirrer may be operated inside the chamber. Users should verify the equipment's temperature rating, dimensions, heat generation, power requirements, and effect on chamber airflow before use.\u003c\/p\u003e\n\u003ch4\u003eIs the door on the IMH750-S lockable?\u003c\/h4\u003e\n\u003cp\u003eThermo documentation is inconsistent on this particular point. Advanced Protocol Security incubators are generally associated with restricted-access door features, but some Thermo literature specifically excludes the large-capacity models from the lockable-door specification. \u003cstrong\u003eThe physical door configuration should therefore be confirmed on the individual IMH750-S before purchase.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch4\u003eIs this Thermo Heratherm IMH750-S refurbished?\u003c\/h4\u003e\n\u003cp\u003eUsed Thermo Scientific Heratherm IMH750-S incubators offered by \u003cstrong\u003eAmerican Instrument Exchange\u003c\/strong\u003e are inspected, cleaned, and tested prior to shipment.
