Description:   Great for studying large one-dimensional accelerations.

Description:   Measure fluorescence and absorbance spectra of myriad samples.

Description:   Robust and accurate portable visible light spectrophotometer.

Description:   Squeeze and Study

Description:   You can make fast, accurate measurements of dissolved oxygen concentration in water samples using our Dissolved Oxygen Sensor. <BR><BR>•Range of 0 to 14 mg/L (ppm) of dissolved oxygen.<BR><BR>•Built-in temperature compensation, which means you can do your calibrations in the lab, and then make measurements outdoors without having to recalibrate. <BR><BR>•Fast response time, reaching 95% of full reading in 30 seconds. <BR><BR>•Great for biology, chemistry, ecology, or integrated science courses. <BR><BR>Disposable caps with pre-fit membranes allow you to quickly and conveniently change membranes. An extra membrane cap is included with each probe. <BR><BR>Calibration is easy with this sensor. Simply place the electrode in the zero-oxygen solution provided with the probe for the 0% calibration point. For the 100% calibration point, place the electrode in air (or better yet, in water-saturated air, using the provided calibration bottle). The probe can be calibrated in any units you choose: % dissolved oxygen, mg/L, or ppm dissolved oxygen.<BR><BR>The DO-DIN and DO-BTA include the dissolved oxygen probe, zero-oxygen solution, extra membrane cap, a 100% calibration bottle, electrode filling solution, and a probe information booklet.

Description:   Map light intensity vs. position for various slit geometries.

Description:   Codey rocky combines easy-to-use robotic hardware with graphical programming to provide students an introduction to coding.
