Regular maintenance increases the life of your instrument while meeting the ever-increasing demands of quality assurance. Depending on the working environment of your device, annual maintenance is recommended.

We offer a cost-effective maintenance check: in addition to preventive maintenance, your device is professionally cleaned, checked, adjusted and calibrated. On request, we also carry out a VDE examination according to DGUV. Of course, you will receive a detailed maintenance and calibration record for your documents, which documents the work carried out comprehensibly.

Even the most reliable device may be broken once. Repair work is carried out quickly and professionally by our experienced service team. Like the maintenance, we offer our repair services as a service to you on site or in our service center.

Return your device | Return Form

You would like to send your A.KRUESS device to our service center for maintenance or repair? For the return we provide a PDF form, which you must fill in completely and attach to the return. The form contains your error or task descriptions as well as important safety information.

Many laboratories work with biological, infectious, radioactive or toxic substances. This can lead to residues on the devices. In order to protect our employees, we ask you to carry out a thorough cleaning, possibly decontamination and disinfection of the respective device before returning it.

Please note that our service team can repair or maintain your device only upon receipt of the completed return form. Shipments without this certificate cannot be processed for security reasons and will be returned to the sender at a charge.

Bridging device for repair and maintenance

Your device must be repaired or recalibrated. However, you cannot do without your device during this service period and require a bridging device. Then a rental option is a good way to avoid costly downtime.

Test device for rent

Of course, there are other reasons for using a rental device. Perhaps you would like to test an A.KRÜSS device and make sure it meets the requirements for a scheduled application. In this case, the rent is an optimal solution, because you can use the device process-oriented and ensure that it works on demand. You don’t enter into a time-related, financial commitment and there is no unnecessary capital commitment. Another plus: In the case of a purchase, the rental fee is credited with up to 100% of the purchase price.

A rental device is also recommended for project-related, time-limited orders and for production peaks. This allows you to meet a short-term increase in equipment requirements, maintain flexibility and keep your costs calculable and plannable.

A.KRÜSS rental devices are always state-of-the-art and meet the DQ / IQ / OQ / PQ / DQ quality requirements of devices and systems. This ensures that you can work in compliance with the GMP guidelines and various international standards.
