Re-Certified Gilson Pipetman L Pipette

A. Approval Processes

The requirements for product return are as follows:

• The product is eligible for return under section (B) below.
• The customer makes the request for return within 30 days of the applicable product’s shipment date.
• The request is not a claim that the product is defective (product defect claims are not covered by this policy, but rather by the warranty terms in the applicable customer contract or the Yalist Warranty Policy).

Upon approval for a product return, Yalist will issue a “return authorization number” to the customer, which may be used at any time within the next 30 days to return the product to Yalist.

B. Product Eligibility

Products are eligible for return to Yalist as follows:

• When the product has been ordered by the customer in error, the following types of products are NOT eligible for return:
  
  - Custom products (i.e, products designed, manufactured or configured to meet specific customer requirements);
  
  - Repair parts that are flagged by Yalist as non-returnable; Products with shelf life.
  
  - Dangerous or Hazardous Materials
  
  - Opened Software
  
  - Opened/Used Products
  
  - Obsolete Products
  
  - Cool or Cold Shipments
• When there is a Yalist error associated with the product, including the following:
  
  - the Customer receives a product different from the product ordered;
  
  - the Customer receives a product damaged in transit; or
  
  - the customer receives a “DOA” (dead on arrival) product
• Any product that is identified as eligible for return by Yalist.

C. Product Return Charges

• For returns based on customer error, Yalist may at its discretion charge 15% of the net purchase price of the product as a return/restocking fee. If a return fee is charged, it may be deducted from the return credit to the customer.
• For returns based on customer error where the customer has operated the product, Yalist may at its discretion charge an additional fee for the refurbishment of the product. If a refurbishment fee is charged, it may be deducted from the return credit to the customer.
• For returns based on customer error, the customer will pay return freight charges to the Yalist specified location.
• For returns based on Yalist error, Yalist will pay return freight charges and the customer will not be charged any return/restocking or refurbishment fees.

D. Release of Credit

Credit memoranda over US$500 (or the local currency equivalent) will not be issued to the customer until the product has been physically received by Yalist. In its discretion Yalist may provide credit memorandums under $500 to the customer prior to product receipt.

It has been disassembled, inspected, fully cleaned, and calibrated with our Level I service by a trained technician. The seal and O-Ring have been replaced as per manufacturer's recommendation. The internal components are in excellent condition and the pipette draws evenly and seals well. The aspiration stroke is smooth and responsive. While in excellent cosmetic condition, the pipette may show signs of light wear or marking under close inspection. This does not have an affect on performance or  calibration.

This pipette has been calibrated and found to be within manufacturer's specification. ISO 17025 calibration available upon request.

All pipette calibrations are performed using the gravimetric method under controlled environmental conditions with balances traceable to NIST standards. Calibration is conducted in accordance with recognized industry practices and ISO 8655 guidelines to verify pipette accuracy and precision.

Each calibrated pipette is returned with a calibration label and a calibration summary report documenting the service performed. Optional detailed data collection and reporting are also available upon request for laboratories requiring full measurement records.
