People keep calling for greater savings not willing to buy brand new and asking for gently used balances and we are listening. Our strong relationship with Sartorius allows us to now offer balances that were used for sales demonstration, trade shows, or a customer that claimed was defective and was returned, but no evidence of failure was found. All balances meet the manufacturer specifications and are calibrated by factory trained Sartorius technician prior to shipping to you. The balances have all the original packing material and operation manual, but the box will show signs that it was shipped before to another customer. The balance and weigh pan may have some small scratches that may show cosmetically that the unit is not brand new, but the balance will perform as a brand new unit. Sartorius classifies these balances as DQE - Demo Quality Excellent. All demo balances carry a limited 12 month manufacturer warranty.
