Parts and Service
• If a problem should arise, please contact your local laboratory apparatus dealer
through whom you purchased the Labconco products. Please include Labconco
catalog and serial numbers on all phones or letter inquiries to obtain prompt action
on your particular unit. Consult nameplates to obtain this information. If contacting
Labconco directly, please furnish the name of the dealer from whom you purchased
the equipment.
CAUTION: Do not bend wires or allow wires to fold up between bottom of heater
casing and insulator board. Heater and sensor life will be greatly reduced if heater is
not installed correctly.
WARNING: PERCHLORIC ACID IS A VERY RAPID OXIDIZER. IT
COMES TO A BOIL AT RELATIVELY LOW TEMPERATURES, WITH THE
LIQUID CONTENTS TOTALLY EVAPORATED IN A SHORT AMOUNT OF
TIME. THE RESIDUE WHICH REMAINS AFTER THE LIQUID IS DRAWN
OFF BECOMES ANHYDROUS AND VERY UNSTABLE.
FOR THIS REASON, LABCONCO WARNS AGAINST THE USE OF
PECHLORIC ACID WITH THIS EQUIPMENT AS A REACTION COULD
RESULT.
