Lovibind XD 7000 Spectrophotometer
The Lovibond XD 7000 is a benchtop Vis spectrophotometer with reference beam technology for potable, waste and process water testing. This includes over 150 pre-programmed and pre-calibrated Lovibond® methods including barcoded vials, barcoded methods and barcoded reagent packaging remove the need to ever search a list for a method.
The Lovibind XD 7000 is ideal for Laboratory analysis of Potable Water, Waste Water and Process Water. It is well equipped for R&D, Quality Control, Method Development and Production Laboratories with easy to follow method programming and standard functions such as Absorbance/Transmission, Spectral Scanning, Kinetics and Multi-Absorbance modes.
The internal barcode scanner automatically recognises all Lovibond pre-filled Tube Tests for COD, Nitrate, Phosphate, Ammonia etc when inserted into the instrument. In addition, ALL the Lovibond pre-programmed tests can be automatically selected using the external barcode reader supplied. Barcodes are found on the reagent packaging and the method instruction so you never need to search through a list.
Save on reagents costs against other Spectrophotometer brands. The instrument's built in pre-defined zeros allow you to use all the reagent vials for samples. Our low cost reagents can save you money without compromising on quality. The instrument checks the size of vial you are using and will not measure if you've used the wrong one. This ensures accuracy and confidence in your results.
The XD 7000 integrates easily into your Quality Management System with multi layer access rights and features include on-board QC protocols for sample matrix, method and reagent interference; internal data storage with date/time/alpha-numeric id stamp.

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 ā 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)

The material from which the cell is made may affect the measurements: plastic cells are more subject to scratching and discolouration and may be subject to chemical or thermal damage. Common materials are borosilicate or optical glass. Both are equally transparent to visible light, but borosilicate glass is more resistant to thermal shock. If you need to heat your samples to above ambient temperature to make them transparent for measurement, borosilicate cells in a heated instrument are recommended. This avoids incorrect results as samples cool or swirl due to temperature changes. Although more resistant, Borosilicate cells are not invulnerable: we strongly recommend samples are placed in the cell at room temperature and then heated in an oven to the required temperature.
Any mess on the cell or the instrument leads to inaccurate results, particularly with automatic instruments whose enhanced precision makes them more sensitive to contamination.
If the cell is dirty, smeared or dusty, it will scatter light, making the detector see the sample as darker than it actually is. Always ensure that the clear ends of the cell are clean and completely free from fingerprints etc. These marks can be removed with a soft cloth. You should also clean a cell before using it the first time: the wrapping, while stopping dirt and dust, leaves a small residue on the surface of the glass.
Oil contents can be removed using a soft brush and by washing gently in lukewarm soapy water (hot water might cause the cells to crack). Particularly stubborn samples can be carefully removed with a solvent like isopropanol. Once the cell has been cleaned, flush it first with tap water, then rinse in de-ionised water to remove any tap water minerals. Turn the cell upside-down to drain and dry.
While damage or dirt on a cell is easily visible, the same may not be true of contamination of a sample chamber, which can build up over time inside the instrument and is not easily visible. To guard against this, it is important to routinely carry out conformance checks using liquid or glass references. These ensure that an instrumentās long-term accuracy is monitored and maintained
Liquid references have several advantages, most importantly that the instrument is being tested using standards similar in nature to the samples being measured. Specifically, liquid references can highlight potential problems in sample preparation and measurement procedures (use of the correct path length, cleanliness of the cell, its correct positioning), as well as the overall accuracy of the instrument.
Glass standards have advantages in their ease of use and shelf life. They are also impossible to spill, take up less space and are easily cleaned. Individual filters and sets for a range of instruments and colour scales are available. Each is provided with a certificate of conformity showing the certified value, acceptable tolerances for the scale, nominal value and instrument.
A vital aspect of correct practice is to ensure the right cell is used for the measurement. Some colour scales incorporate a path length correction into the method. Here it is possible to use different path length cells and enter this path length into the instrumentās settings to calculate the correct result. In other cases, one must either use the default path length, where there is one, or, when you have an option, always report the result with the actual cell used. Details of which path lengths are recommended for which scales can be found on the TintometerĀ® Groupās website.
Older instruments should be sent back-to-base for calibration. On return, you should receive a certificate of calibration to ISO 9001 for the instrument, listing the standards used, their pass/fail tolerances and the measurements given at the time of the test.
An alternative process is RCMSi where tightly controlled calibration liquids are measured via the Calibration function of a LovibondĀ® PFXi. Data is electronically communicated to a secure server and compared to Master Data. If the data passes within tolerance, a Certificate of Calibration is made available to the user. This ensures a PFXi instrument is operating correctly and fully calibrated using ISO 17025 certified standards. Using this system allows the operator to get the confidence of a back-to-base calibration, without needing to transport the instrument: saving cost, time and environmental impact.
By using one or more methods of verification, you can be confident that the results that your instrument is giving are consistent over time, as well as with other instruments reading to the same test methods. Ensuring the accuracy of an instrument prevents potentially costly mistakes, immediately picking up deviations so fixes can be applied.

The chemical reaction, known as the Maillard reaction, between amino acids and reducing sugars gives your beer the identifiable brown and amber hues. Not only is the colour important by effecting the consumer's sensory anticipation of the beer's taste, monitoring the colour will also help diagnose if there are any issues in the production of the beer. To maintain the same high quality be...

Spectrophotometers are relied on by a wide range of laboratories, for tests ranging from specific parameters, like chlorine or metals concentrations, right through to complex analyses of reaction kinetics. When choosing a spectrophotometer the range of specifications and price is vast, so take the time to list the features you need before you buy and make sure you choose the right one. [c...
