Our first class technical staff are always on hand to provide expert advice, training courses and seminars. We specialise in bringing new technology to market. We work with manufacturers around the world to apply new technologies to the changing analysis requirements of our customers.

QCL Support Services Emergency Breakdown Technical Support On-site Repair Maintenance Installation Calibration

Our extensive installed base of instrumentation is supported by our service centre, staffed by a dedicated team and supplemented by engineers based at strategic positions around the UK, enabling us to deliver a quick response time to service requests and breakdown emergencies. We pride ourselves in maintaining our average response time to a call-out at less than 24-hours. We also support our customers who work 365 days a year with a weekend and Bank Holiday call-out service. We service a wide variety of dairy instrumentation, electrochemistry and laboratory equipment. We also provide a technical support service.

We understand that properly maintained equipment is less likely to let you down, so we have a range of Service Contract Cover options to keep your equipment in optimum condition. Contract holders receive priority on emergency breakdowns and also benefit from preferential service rates. Some customers may find it more convenient or less costly to send their instruments to our workshop for repair, servicing or calibration. The turnaround time is usually within 48-hours of receipt.

Rapid IR Compositional Analysis The Delta LactoScope FTIR Advanced is the complete flexible dairy analyser that is used for the analysis of liquid milk, milk concentrates, creams, whey, whey derivatives, yogurt, ice cream, diluted products, hard cheese and more. It measures the complete spectrum of a dairy sample allowing the analysis of many components simultaneously. It has a capacity of up to 120 samples per hour and includes automatic zeroing and cleaning. The Delta Lactoscope Filter is a stand-alone versatile analyser for liquid milks, creams, cultured products and ice creams. It measures up to 150 samples per hour and features auto zero and cleaning with 5 litre tanks. It provides liquid dairy and cheese processors with simple, accurate and cost effective routine analysis.

Pasteurisation Verification The Fluorophos ALP Test System takes the phosphatase test for pasteurisation verification to its highest level, detecting contamination of as little as 0.003% raw milk contamination. The Fluorophos ALP Test is the UK reference test and has been approved by the ISO (ISO118161), IDF, Interstate Milk Shippers and AOAC. It is more sensitive, quicker and reproducible than older methods. The high sensitivity of the Fluorophos Assay allows trends in pasteuriser performance to be monitored. A gradual deterioration can be identified and rectified well in advance of a legal failure.

Cryoscope The 4250 single-sample cryoscope provides fast and accurate measurements of extraneous water in milk. Combining advanced features with simplified operation, this low maintenance, reliable high performance laboratory instrument measures up to 35 samples per hour. Routine testing can be accomplished with just two buttons. The 4250 uses the industry standard thermistor freezing point method to precisely determine the level of extraneous water.

Sy-Lab Rapid Microbiology systems rapidly and automatically detect and enumerate a wide range of pathogenic and spoilage organisms. High bacterial counts can be detected in hours rather than days allowing same-day microbiology positive release in many cases. The innovative M and E value impedance method provides the versatility to address a broad range of applications. Simple sample preparation and no manual plate handling and counting can increase sample throughput reducing product release times.

The Quant Fourier Transform Near Infrared (FT-NIR) system is the modern solution for rapid compositional analysis of any food, drink or agricultural sample. Accurate and rapid analysis of sample constituents and properties increases process efficiency, allows tighter process control, enhances quality assurance and increases productivity. The Quant needs no technical knowledge to operate, is ultra reliable and requires no engineer servicing over its lifetime. When situated in the factory plant, operators can check and trim a process in real-time. The modular sample accessory bay means that one system can be configured to analyse different sample types.

The TitraLab titration workstations provide accurate results at the touch of a button. This versatile instrument is simple to use and provides a cost effective solution for routine titrations in a wide variety of food products. For total automation our sample changers are capable of handling multiple combinations of titrations, direct pH, ion and conductivity measurements.

pH pH is an important determinant in the shelf life of foods. Together with temperature it ranks as one of the most important indicators of food quality and safety. Expertise gained from 30 years experience in electrochemistry enables us to develop methods for a wide range of applications. Our pH meters and electrodes combine sophisticated technology with simplified operation and exceptional long-life performance.

The new Dual Star meter is ideal for simultaneous measurement of two samples or concurrent measurement of two parameters, such as pH and sodium, from one sample. Wastewater laboratories can measure pH and ammonia levels quickly and easily. Food processing facilities can measure pH and sodium levels concurrently.

Automated Chemistry Primary or Reference analysis techniques such as Kjeldahl or Soxhlet involve the use of hazardous chemicals at high temperatures. Automating these digestions and distillations reduces operator exposure to dangerous chemicals, speeds up reaction time and improves recoveries. Our range of high quality equipment promotes advanced safety features and has a range of capacities to suit all laboratories. z z z z z z
