Have you considered your servicing requirements? Much like a car, scientific instruments may need a bit of care to keep them working reliably and at their most accurate.
The Camlab Service Department have over 60 years experience in scientific instrumentation. We have a number of highly qualified internal and field-based service engineers able to perform a variety of jobs including preventative maintenance servicing and calibration.
Camlab can offer yearly service contracts which include two main types of preventative maintenance/calibration services – the back to base service and an engineer visit to your site. These options are can be offered with differing turn around times depending on the instrument type and your requirements along with loan instruments if available.

A typical preventative maintenance service includes the following: Inspection and testing of the unit
Dismantling, cleaning and inspection of the key parts
Correction of minor defects including adjustments if necessary
Reassembly and testing
Take post adjustment / cleaning readings
Supply of calibration certificate
Return of the item to you (back to base services)

What is conductivity? Conductivity is a measure of the ability of a substance to conduct an electrical flow through it. In water, many compounds and molecules (such as dissolved salts and inorganic materials) dissociate into constitutive ions. Ions are small sub-atomic particles and carry with them an electrical charge; either positive (cations) or negative (anions). These particles help condu...
Mettler Toledo have released their new FiveEasy range of benchtop meters for pH and conductivity. The new models, still part of the FiveEasy family, have been redesigned and have had extra features added. We were impressed at the compact, clever design and the flexibility the new range offers. [caption id="attachment_8141" align="aligncenter" width="300"] The new FiveEasy range, but what ...
Laboratories using a deioniser system to generate deionised (or DI) water in house should test the water produced regularly, to ensure the system is working well and producing water of the required purity. [caption id="attachment_8125" align="aligncenter" width="300"] How can you test your DI water is pure enough?[/caption] Conductivity is usually used as a good indicator of the quality, ...
