Consistency Matters In Laboratory Situations For Repeatable Test Results

Television programs like CSI and Bones have made laboratory equipment a part of popular

culture and ignited interest in the fields of forensic science and research. What does this mean for the surrounding DNA profiling and drug testing laboratory fields? Many leaders in scientific researching equipment are being able to showcase their products to more laboratories simply by having them demonstrated.

Laboratories contain many different kinds of sensitive measurement equipment. Depending on the type of laboratory and the materials being handled and processed there it might have a gas-chromatography mass-spectrometry machine identifying different substances in a test sample, a centrifugal evaporator for removing solvents from test samples, a microscope for detailed visual analysis, a Amplified Fragment Length Polymorphism analysis machine to measure DNA profiles, and generalized equipment like freeze driers, coolers and chillers, glassware and washers.

While laboratory equipment should always function at its best, sometimes it needs repairs. The specialized nature of such delicate equipment and the investment of thousands of dollars requires specialized expertise and repairs.

Centrifugal evaporating technology is used to remove solvents from laboratory samples in a gentle and non-comprising method. Solvents react with samples in different ways and require special care to remove. Some solvents are flammable at high temperatures and can create violent explosions if not dealt with properly. If an test sample contains a toxic or explosive contaminant, it can destroy the testing equipment and potentially harm the laboratory technician handling the equipment, not to mention corrupting the sample.

The centrifugal force generated by spinning the centrifuge rotor creates a pressure gradient within the solvent contained in the tubes or vials. The samples boil from the top down, helping to prevent "bumping". The most advanced systems apply the vacuum slowly and run the rotor at speeds of 500x gravity - this system is proven to prevent bumping and was patented by Genevac in the late 1990s.

While research methods and the machines designed to help researchers discover new advances in biological technologies are constantly advancing, it is vital to have consistent measurable and repeated results using existing equipment. Equipment needs to be repaired speedily and accurately to avoid costly downtime in processing samples. Rectification of issues must be done accurately and swiftly by trained professional technicians.

Be certain when choosing a repair facility of its qualified and quality training and avoid risks to delicate machines. Consistency matters so make sure the laboratory equipment is dependable and consistent. Advances in technology may result in improvements to processes for equipment repairs, being aware of this makes a great difference in speed and accuracy of repairs.
