One of the primary functions of a hospital laboratory is to run tests to enable a diagnosis of the patient. Accuracy in the lab is critical to the health of those whose tests are being run. This requires that all equipment should be reliable and quick and easy to use for the technicians. In a hospital, one of the most used is the lab centrifuge. The ability of these to perform is determined by many factors including the specifications of the unit and its requirements in the lab. Finding the right lab centrifuges will necessitate examining the laboratory needs for the unit as well as its durability and longevity.
Lab centrifuges are used to break samples down into their various components by spinning them in the unit, until the substances in the sample settle themselves into layers of varying density. Blood is frequently spun in these in order to separate out the red blood cells, from the plasma, from the platelets. This is required most times blood tests are ordered. Depending upon the solution that is to be centrifuged, the speed of the unit will differ. When you are looking for a quality model, you should find one that has adjustable acceleration rates. This enables the widest range of materials which can be successfully separated through spinning them in the machine.
You also need to find the highest quality of lab centrifuges. Poorly made units have uneven acceleration rates, or may even be wobbly, not unlike an unbalanced washing machine. There should be smooth acceleration available in any model you acquire. In order to steadily and smoothly speed up, the unit should also have optional counter weights that can be added in the instance of running an odd number of tubes. There should not be any wobbling. Timing is also an important quality in any centrifuge. Over processing can ruin a sample and require the patient to return to the lab for a replacement. No one wants this to happen. It’s inconvenient, and it costs money. To prevent this, you will need a lab centrifuge with a timer. A unit with a timer alerts the technician when it is time to remove the samples.
When you purchase a lab centrifuge you will also need tubes in which to spin the samples. These tubes range greatly in size, material, and quality. For the most cost effective centrifuge tubes, you might want to look for disposable models. These are the most sterile and are ideal for bio-hazard samples. After use, they can simply be discarded, and you don’t have to worry about cleaning. Look for polypropylene, which is the most frequently seen material for disposable, pre-sterilized models of tubes. The sizes of the tubes can vary from 1.5 to 50 milliliters. Colored tubes are also available to facilitate identification. Furthermore, you should be certain to have an ample supply of racks for the storage of processed and unprocessed samples. These keep the lab neat and orderly, increasing its efficiency and, thus, the accuracy of its results.
