Item was being used in a lab and we were told it works.  We confirmed, as you can see in pictures, by running the unit for a short period.  However, there is a sign that was attached that we were unable to get clarity on do to movement at the organization.  There is a picture of the sign.  The sign says thst the water bath cannot be used over 70°C.  I do not know the parameters of the machine so I do not know if it is a defect or a warning to untrained personnel in that particular lab for what they were working on at the time.  You are purchasing this item with all the knowledge about its functionality that I have at this time.  This item is being sold as is with full disclosure.  There is some flexibility in the price. If you are generally interested make a good faith offer and we will accept or counter the offer.
