This Vistalab Technologies 100-1000 uL Ovation Bionatural Pipette without Power Supply is in good condition and was removed from a working environment. Pipettor does not include power supply required for operation. This issue is reflected in the list price. Although we cannot fully test, we guarantee functionality with a 30-day, full money back free return policy. We urge customers to view all photos as they show overall condition, included accessories and useful information. We will be happy to provide additional information as well as photos so please feel free to contact us with any questions.

Please note: As seen in photos the plunger cap is missing on the top of unit (does not affect functionality).
