Questions regarding this device
The legal warranty period for our devices is 24 months from delivery date.
All used instruments of Labexchange are subject to a technical inspection before delivery and will be supplied only, when they function perfectly well. The verification and functionability is documented by a service report of an independent service company. The Labexchange Fullguarantee is 60 days from delivery date. Malfunctions occurring within the warranty period will be corrected by us free of charge. (Valid for countries within the EU and CH)
Our certificate of operativeness ensures a technically perfect condition.
You are on the safe side with our used laboratory and analysis systems! For even more security during the purchase, we are granting the Labexchange right of return.
Return your laboratory or analysis system simply without explanation.
Our special terms and conditions are to be applied:Labexchange right of return(https://www.labexchange.com/fileadmin/user_upload/pdf/downloads/en/Rueckgaberecht_08_18_E.pdf)
On demand, we verify the option of an extension of warranty for your device. If possible, the period of warranty is 6 months for 10 % extra charge and 1 year for 20 % extra charge on the list price. (Valid for DE, AT, CH, FR, NL, BE, LU, GB and IR)
Play it safe! We are pleased to offer you the installation of your laboratory equipment. Our qualified technicians install the device on your desired date in the laboratory, so that you can work quickly and safely with your new laboratory equipment.
The installation of the equipment by Labexchange brings further advantages. You thereby obtain a guarantee extension to 6 months and you have also the right to the Labexchange Repurchase Guarantee. You receive sensible laboratory equipment and analytical systems as well as much of the available laboratory hoods, already incl. installation.
