Laboratory or analytical scales are mainly used in specialized laboratories, in Universities, medical schools, pharmacies and research centers. They are high precision instruments used to measure not only the weight of an item, but to also analyze the amounts of various chemical components within a given solution. They are the main tools researchers use to find key values in their studies, thus they must be very accurate. Without flawless readings, research is sometimes compromised and a lot of money can go to waste, so investments are usually made in quality weighing scales. The readings offered by a laboratory scale must be clear and precise because based on the collected numbers further analytical interpretations and statistical calculations usually follow. In case you need to use such a scale in your own studies, know that there are plenty of models to choose from.
The analytical and laboratory scales you can find nowadays have very modern features which can simplify your work a lot. They don’t raise any operational problems; they are easy to maneuver and have different capacity sizes and great readability. Not to mention that some functions make them far superior to traditional weighing scale tools – for example, you can use a diversity of units of measurement: milligrams, grams, ounces, pounds, carats, grains, pennyweight, troy ounces, kilograms, specific gravity, percentage and many more. They are provided in various designs, one better looking than the other. Some of them are more sensitive, thus they are suitable for more delicate weighing tasks, while others are designed for heavier loads. Some of them can even be connected to other devices such as printers, making them very practical.
The choice in scales varies even more, with brands. Sartorius, Ohaus, AND Weighing are only a few examples of analytical and laboratory scales worth using in high-level research. These manufacturers have amazing offers in terms of very precise weighing scale tools, with the most advanced features on the market and there are quality items at various prices for any type of analytical work. Costs vary from a hundred dollars to a few thousand dollars and with the right website to purchase from you can get the shipping free. These weighing tools are excellent value for money and the most expensive ones are usually purchased by institutions looking to invest in their growth by making use of state of the art technology. The less expensive ones can even be purchased by Universities on a budget and various schools looking to improve their students’ level of study. Since they are key items in research at any level, they are worth investing in.
How does one choose an analytical weighing scale? Well, the first aspect one looks at is the price. As already explained, the variety of scales available on the market means you can easily pick something within your budget. However, since this is a long term investment, one should strive to purchase a scale with the right performance; being modern looking or having features can be bonus, but the most important aspect is that it is accurate and long lasting. The second aspect is one more difficult: the features of the scale are what one will be making use of so the choice depends on the purpose of the scale, the age and skill of those using it and the tasks it needs to perform. Looking at the laboratory work that the weighing scale will be used for is the best start. It is also useful to know who will be using it and their prior experience with such tools. If the person using it is a Doctor, the item ought to be of a higher level of complexity than that used by a student in middle school. Also, if one has just started using laboratory and analytical scales and is not too accustomed to them, a simpler model may do. Simple features will not put anyone in any difficulty.
