 Warranty Statement 

 
Scientific Systems, Inc. (SSI) warrants that instruments or equipment manufactured by it for a period 
thirty-six (36) months from date of shipment to customer, against defects in materials and 
workmanship under normal installation, use and maintenance.  Expendable items and physical 
damage caused by improper handling or damage caused by spillage or exposure to any corrosive 
environment are excluded from this warranty.  The warranty shall be void for Polyetheretherketone 
(PEEK) components exposed to concentrated Nitric or Sulfuric acids which attack PEEK, or 
methylene chloride, DMSO or THF which adversely affect UHMWPE seals and PEEK tubing.  Any 
defects covered by this warranty shall be corrected by replacing or repairing, at SSI’s option, parts 
determined by SSI to be defective.   
Spare or replacement parts and accessories shall be warranted for a period of 12 months from date of 
installation at customer against defects in materials and workmanship under normal installation, use 
and maintenance.  Defective Product will be accepted for return only if customer returns them to SSI 
within thirty (30) days from the time of discovery of the alleged defect, and prior to return, obtains a 
Return Goods Authorization (RGA) number from SSI, and provides SSI with the serial number of 
each instrument to be returned.  Freight costs for the return of defective Product is the responsibility 
of SSI.  SSI shall specify the freight carrier for returns. 
The warranty shall not apply to any Product that has been repaired or altered except by SSI or those 
specifically authorized by SSI, to the extent that such repair or alteration caused the failure, or to 
Product that has been subjected to misuse, negligence, accident, excessive wear, or other causes not 
arising out of a defect in material or workmanship. 
 
The warranty shall not apply to wear items, specifically:  

Check Valves 

 

Piston and Wash Seals 

Pistons 

Pulse-Damper Diaphragms  

Inlet Lines 

Filter Elements 

The following is the exclusive procedure by which to make claims under this warranty.  Customer 
shall obtain SSI’s oral or written authorization to return the product and receive a Return Goods 
Authorization (RGA) number.  The Product must be returned with the RGA number plainly visible 
on the outside of the shipping container to SSI.   It must be securely packed in a rigid container with 
ample cushioning material, preferably the original packaging.  All claimed defects must be specified 
in writing, including the RGA number, with the written claim accompanying the Product.  Product 
shall be shipped to SSI at customer’s expense.  SSI shall bear the expense of return shipment. 
If it appears to SSI that any Product has been subjected to misuse, negligence, accident or excessive 
wear, or is beyond the warranty period, customer shall be notified promptly.  SSI shall notify 
customer of its finding and provide an estimate to repair such Product at the then current rates for
