Warranty

Products manufactured by Seller are warranted against defects in materials and workmanship for twelve

(12) months from date of shipment thereof to Customer, and Seller’s liability under valid warranty

claims is limited, at the option of Seller, to repair, replacement, or refund an equitable portion of the

purchase price of the Product. Items expendable in normal use are not covered by this warranty. All

warranty replacement or repair of parts shall be limited to equipment malfunctions which, in the sole

opinion of Seller, are due or traceable to defects in original materials or workmanship. All obligations of

Seller under this warranty shall cease in the event of abuse, accident, alteration, misuse, or neglect of

the equipment. In-warranty repaired or replaced parts are warranted only for the remaining unexpired

portion of the original warranty period applicable to the repaired or replaced parts. After expiration of

the applicable warranty period, Customer shall be charged at the then current prices for parts, labor,

and transportation.

When products are used with toxic chemicals, or in an atmosphere that is dangerous to the health of

humans, or is environmentally unsafe, it will be the responsibility of the Customer to have the product

cleaned by an independent agency skilled and approved in handling and cleaning contaminated

materials before the product will be accepted by Agilent, Inc. for repair and/or replacement.

Reasonable care must be used to avoid hazards. Seller expressly disclaims responsibility for loss or

damage caused by use of its Products other than in accordance with proper operating procedures.

Except as stated herein, Seller makes no warranty, express or implied (either in fact or by operation of

law), statutory or otherwise; and, except as stated herein, Seller shall have no liability under any

warranty, express or implied (either in fact or by operation of law), statutory or otherwise. Statements

made by any person, including representatives of Seller, which are inconsistent or in conflict with the

terms of this warranty shall not be binding upon Seller unless reduced to writing and approved by an

officer of Seller.

Warranty Replacement and Adjustment

All claims under warranty must be made promptly after occurrence of circumstances giving rise thereto,

and must be received within the applicable warranty period by Seller or its authorized representative.

Such claims should include the Product serial number, the date of shipment, and a full description of

the circumstances giving rise to the claim. Before any Products are returned for repair and/or

adjustment, written authorization from Seller or its authorized representative for the return and

instructions as to how and where these Products should be returned must be obtained. Any Product

returned to Seller for examination shall be prepaid via the means of transportation indicated as

acceptable by Seller. Seller reserves the right to reject any warranty claim not promptly reported and

any warranty claim on any item that has been altered or has been returned by non-acceptable means of

transportation. When any Product is returned for examination and inspection, or for any other reason,

Customer shall be responsible for all damage resulting from improper packing or handling, and for loss

in transit, notwithstanding any defect or non-conformity in the Product. In all cases, Seller has the sole

responsibility for determining the cause and nature of failure, and Seller’s determination with regard

thereto shall be final.

If it is found that Seller’s Product has been returned without cause and is still serviceable, Customer will

be notified and the Product returned at its expense; in addition, a charge for testing and examination

may be made on Products so returned.
