Return of defective centrifuges or parts 

Although we exercise great care during the production of our products, it 
may be necessary to return a unit or accessory to the manufacturer. 
In order to ensure the quick and economical processing of returns of 
centrifuges, spare parts, or accessories, we require complete and extensive 
information concerning the process. Please fill in the following forms 
completely, sign them, enclose them with the return package, and send 
them together with the product to: 
Sigma Laborzentrifugen GmbH 
An der Unteren Söse 50 
37520 Osterode (Germany) 

 

1.  Declaration of decontamination

 

As a certified company and due to the legal regulations for the 
protection of our employees and of the environment, we are obliged to 
certify the harmlessness of all incoming goods. For this purpose, we 
require a declaration of decontamination. 
•  The form must be filled in completely and signed by authorised and 

specialised personnel only. 

•  Affix the original form in a clearly visible manner to the outside of the 

packaging. 

 

 

NOTE 

We will return the part/unit if no declaration of decontamination is provided! 

 

 

 

 

 

2.

Form for the return of defective parts

 

This form is for the product-related data. They facilitate the assignment, 
and they enable the quick processing of the return. If several parts are 
returned together in one packaging, please enclose a separate problem 
description for every defective part. 
•  A detailed problem description is necessary in order to perform the 

repair quickly and economically. 

 

 

NOTE 

If the form does not include a description of the malfunction, neither a 
refund nor a credit note can be issued. In this case, we reserve the right to 
return the part/unit to you at your expense. 

 

 

 

•  Upon request, we will prepare and submit to you a cost estimate 

prior to performing the repair. Please confirm such cost estimate 
within 14 days. If the cost estimate has still not been confirmed after 
4 weeks, we will return the defective part/unit. Please note that you 
must bear the incurred costs.
