Mettler Toledo DO307 Glass Drying Oven DO307 DO308 Karl Fischer KF

AdID: 14411

Availability: In stock


Fast-Heating 300ºC Drying Oven Tested by Our Technician and in Good Working Order

This drying oven is fully functional and tested by our technician. It reaches 300ºC max, manufactures temperature range fast. The Buchi glass is in good condition with the heating tube being broken and will need to be replaced.

The sample boats are missing from this system and will need to be purchased. This would make an excellent drying oven if a lab had the good glass but needed the heating unit.  

The DO307 is one step below the current model of DO308 which has basically the same features just a new look. Why pay thousands of dollars when you can own this one at a fraction of the cost.

The drying oven is ideal for accurate water determination of solid of viscous samples:
     - Substances that release water only at elevated temperatures
        (Plastics in powder or granular form)
     - Substances that cause side reactions with Karl Fischer
        reagent (oxidizing inorganic salts)
     - Substances that cause problems in the titration vessel due
        to their consistency (fibrous or pasty substances)
     - Substances that are poorly soluble or insoluble (wool, dough,
        tar or coal


Includes a 90-Day Warranty for your protection

We realize that buying a second-hand instrument can be unnerving, therefore we offer a 90-Day Warranty to protect you against any equipment failure or defects.

Technician Tested

Our technician confirms that the drying oven heats up to the specified temperature. He states that the analog is “spot-on” accurate for the temperature.
