Accuracy. Consistency. Reliability. These are the words that best describe Ohaus and the kinds of standards that are always top of mind when they’re designing their products. Their unwavering commitment to high-quality and durability makes them a staple in almost every industry so it’s no surprise that the students enrolled in The Pennsylvania College of Technology’s School of Hospitality’s Baking & Pastry Arts program are finding success with Ohaus balances.
You already know Ohaus has perfected the science of mass measurement with their state-of-the-art balances and scales. They’re constantly improving their capabilities and functions as well as ensuring their products are easy to use. Another field that Ohaus continues to raise the bar in is water analysis and testing pH levels. Their Starter Series line of water analysis products all contains intuitive software that is both straightforward and highly accurate. The Yonkers Brewing Company, located in Yonkers, New York, took notice of this and decided to use Ohaus’ equipment for their brewing process.
To say there have been many advancements in the field of microscopy since the development of the first compound microscope by Zaccharias Jansen in the late 16th century is an understatement. Jansen and his father, Dutch spectacle makers, built the first microscope by using three draw tubes with lenses inserted into the ends of the flanking tubes. They discovered a much larger image than expected; much larger than simple magnifying glass provided. The very first compound microscopes only magnified images between 6x – 9x. Microscopes of today can magnify images to the nanometer.
With as plentiful as magnets are in our everyday lives– from the electronics and motors to our refrigerators covered in them – it’s hard to imagine that there are only a few metals that are naturally magnetic. As we become more gadget obsessed, our need for magnetic materials increases. And now researchers have made magnets out of two non-magnetic metals: copper and manganese. This discovery could be useful in microscopic electronics and sensors.
