Laboratory Centrifuge
The accuracy of patient diagnosis is based upon the efficiency of the lab. Results from tests done there will guide the physician in his recommendations and prescriptions. Reliable equipment such as the often used laboratory centrifuges is vital to the health of the patient. Poorly run tests, or ruined samples could skew the results, which might lead to a misdiagnosis. This could too easily prove fatal for the patient. The task of the hospital and its lab are to save the lives of the patient, not cost them. You will need to acquire high quality lab equipment to be able to trust the results passed along to the physician. A high quality laboratory centrifuge has many features which are critical to its performance. Each of these is crucial and should be carefully weighed when selecting machine for your lab.
The purpose of a laboratory centrifuge is to spin samples in tubes until the substances which compose the mixture settle into layers of varying density. There are three main types of centrifuge: diffusion, isopycnic, and sucrose gradient. Depending upon the materials you need to separate, you might need one of the different types of centrifuge. If you will be needing to separate the various cell organelles from the whole, you will use a diffusion centrifuge. This type is used for cell study and microbiology. By subjecting the samples to repeated filtering and spinnings, the organelles can be extracted from the whole and more closely examined individually. Isopycnic laboratory centrifuges are required for the extremely high speeds necessary for separating the nucleic acids from a DNA strand. This enables the researcher or technician to study the base pairs in the genetic makeup of the sample. Sucrose gradient enables the technician to remove the coating of protected viruses or ribosomes. Like diffusion, it is also a means of extracting the individual cell organelles from the rest of the cell. Your decision for your centrifuge should take into account its purpose, but there are some commonalities shared among quality units for all three types.
You will need high quality laboratory centrifuges in order to assure that you are getting accurate results. If the unit over processes the sample or wobbles during use, it can lead to a need to acquire a replacement sample. At best, it is an inconvenience for a hospital patient, and at the most, it might not even be feasible. To prevent wobbling when the unit is on, some form of counterweights must be used. These could be identical tubes with the same mass. There should also be a safety cut-off that will power down the machine in case an imbalance is detected. A wobbling laboratory centrifuge can cause injuries to the technicians and serious damage to the machine itself. There also needs to be a timer to prevent over processing. These safety mechanisms will ensure the accuracy of the results and the safety of those working in the lab.
For trustworthy results from your laboratory tests, you will need a high quality laboratory centrifuge that is equipped with safety in mind. All three of the main types require this. And procuring the best machines will lend credence to your lab.
