Ohaus Adventurer Pro helped Dr. Darnowski of Indiana University discover new carnivorous plants. Before the first discovery, there were about 500 known carnivorous plants-this number has not changed in 50 years. With the presence of more than 300 different types of triggering plants, the number of known carnivorous plants has also jumped from more than 500 to more than 800, and this discovery is partially due to the contribution of Ohaus Adventurer Pro balance.
"In the summer of 1860, I found that a large number of insects were trapped by the common sundew leaves, which surprised me ... I heard that insects were caught like this, but no further information was available on this issue Got it. "-Charles Darwin," Carnivorous Plant ".
How much progress has been made in our research. As one of the eight Indiana University (IU) campuses, Indiana University (IU) Southeast Campus is proud to provide world-class teacher and student resources. The Department of Biology is no exception, providing school laboratory students with the tools and research experience needed for the next stage of life, so that they can make full preparations.
Ohaus Adventurer Pro full range of products can meet your laboratory weighing needs
Dr. Doug Darnowski is an assistant professor in the Department of Biology at Indiana University (IU) Southeast Campus. By using the key laboratory equipment Ohaus Adventurer â„¢ Pro balance, they can conduct scientific research on carnivorous plants and plants that they suspect may be carnivorous.
Dr. Darnowski's plant research has confirmed the carnivorous properties of certain unknown carnivorous (trigger plants) plants, which has improved understanding of the distribution of nutrients from predators through the distribution of aquatic carnivorous plants and established methods to re-determine that carnivorous plants are endangered (Called tuberous sundew). Before the first discovery, there were about 500 known carnivorous plants-this number has not changed in 50 years. With the presence of more than 300 different types of trigger plants, the number of known carnivorous plants has also jumped from more than 500 to more than 800.
Through a research team composed mainly of university students, Dr. Darnowski recognized the importance of a superior balance. The balance must not only provide accurate weighing results, be easy to use, but also withstand many times of improper use. So he chose two Ohaus Adventurer Pro balances-one balance was used as a "heavy duty" device for his laboratory students, and the other was for his personal use.
Ohaus Adventurer is the perfect laboratory heavy-duty balance
Ohaus Adventurer Pro series top-loading analytical balances provide more standard functions than similar balances. They have many advantages such as simple structure, reliable performance and high precision, which make them widely favored.
"I like this balance, it is not only durable but also simple in structure, because my college students-some of them are freshmen-can easily use this balance. It is very intuitive and can withstand improper use, but still Can provide accurate weighing results, "Dr. Darnowski said.
"In fact, we regard this balance as our main heavy-duty balance-even for measurements accurate to one decimal place-under the use of my college students still maintain excellent performance. In five years, we It has not been repaired. "
In the metabolic research project in the laboratory, plants are fed predatory insects or simulated insects injected with carbon or nitrogen, and after a few days, carbon or nitrogen is transported throughout the plant. These plants are then subdivided (subdivided into flowers, flower stems, stems, leaves, roots, and soil around the roots), and all parts are freeze-dried. Using the Ohaus balance in the laboratory, each part is carefully weighed and reduced to a sample of 2 mg, and then sent to a special agency to determine the amount of additional carbon or nitrogen added to each part of the plant after feeding. How many.
In the research project to re-define carnivorous plants, the research team developed tissue culture media so that they could produce a large number of plants as needed. For weighing the critical amount of plant hormones and weighing plants after cultivation, Ohaus scales play a key role.
"The accuracy, precision and ease of use of the Ohaus balance are important for our research because our plants are small at the beginning and become smaller after drying," Dr. Darnowski said.
Adventurer Pro readability can reach 0.1 mg!
As more and more work needs to be done in the home laboratory, Dr. Darnowski discovered more advantages of using Ohaus balances.
"This balance is sturdy and durable, I can take it home for use, and then take it back to school, so that I can bring it with me as needed, providing me a lot of convenience
Since the Ohaus Adventurer Pro balance has successfully solved the weighing problem of Darnowski and his students, the Department of Biology has made plans to incorporate other Ohaus products into its research projects. "I have used many weighing instruments over the years-I have been using weighing instruments since my college career-my overall impression is that the Ohaus brand is a brand I trust and trust," Dr. Darnowski said. "Some Ohaus balances can be connected to laptops. With the increase in our metabolism research, we are likely to eventually use these functions. It is also an excellent function to directly import sample data into a spreadsheet."
Indiana University ’s Southeast Campus is one of the eight campuses of Indiana University. Indiana University ’s southeast campus offers more than 50 degree programs, and the scenic 177-acre campus is less than 15 minutes from downtown Louisville.
