Our services include:

  • On-site Service

We offer a fixed price annual service contract alternative to individual repairs for all types of equipment - including all material, working time and expenses for repairs.

  • On-site Repair

We repair all types of equipment, regardless of the defect. We typically have all the necessary replacement parts in stock. Should this not be the case, we will do our utmost to help you as quickly as possible. You can expect a repair appointment within a few days, and we promise to get back to our service contract customers the same day or the next day to establish an exact diagnosis and arrange an appointment.

  • On-site Preventive Maintenance

You generally look after your own equipment and typically only call in external help for essential repairs, but feel that your synthesizer or HPLC really needs a service? We can give your equipment a thorough check-up, replace worn parts, calibrate and thoroughly test it. Whilst we may not go quite into as much detail as we do for our reconditioned equipment for resale; you can expect a more thorough level of service than that offered by many original manufacturers.
