Like most electromechanical equipment, Sutter Instrument micropipette pullers contain components that require protection during shipping. Therefore, it is strongly recommended to retain the original shipping box with fitted foam inserts and use it whenever the unit is shipped. If the original box is no longer available, a new box can be purchased from Sutter Instrument. Use of inappropriate shipping containers may void the warranty and has in several cases caused shipping damage that far exceeded the cost of a new shipping box.
