Dual style, interchangeable pans which allow for a broader range of objects to be weighed
Stackability on either platform to maximize storage space when not in use
A spring-loaded zero adjust knob & zero adjust compensation beam for precise measurements
Manual damping device to speed up the weighing process
Removable bowl-type or flat pans allow weighing of a variety of materials
Metal beam provides years of maintenance free classroom use
Built-in storage lock protects the weighing mechanism
Built-in carrying handle
Manual damping device speeds up weighing time
A unique design offering increased durability and superior accuracy by employing a precision engineered metal beam for years of maintenance free classroom use. With its unique design, the Harvard Junior offers the combination of a colorful and inviting plastic two-pan balance with the durability and accuracy of the more expensive Harvard Trip, by incorporating a precision-engineered metal beam and zero adjust compensator. The Harvard Junior is not only the most feature-rich balance in its class, but it includes a free teacher-developed, classroom tested elementary activity guide focused on practical, yet enjoyable activities that link science and math concepts, are standards-based, and utilize common items already found in your classroom or at home.The laboratory balance has come a long way from the standardized polished pebbles used in 2400 BC to measure the weight of goods. It is now a common tool used by industries to provide solid, accurate performance and durability for long-term reliability. You can find a laboratory balance in a variety of categories. There’s a sturdy laboratory balance which is great for teaching. You can also pick one that focuses on precision. And there’s even a laboratory balance for use outside the laboratory. Cole-Parmer has a list of balances to choose from. You can select from Ohaus Cent-O-Gram and Dial-O-Gram. These products provide accuracy and the convenience of an integrated weigh-below balance while allowing students to visualize mass measurement principles. They are also designed with a hanging pan system. There’s also the Denver Summit Analytical which features a backlight display and is known for its precision. There are literally thousands choices but Cole-Parmer also offers an easy-to-use guide to pick the laboratory balance perfect for your needs.
