"Vernier"

Measure fluorescence and absorbance spectra of myriad samples.

Measuring the temperature of a distillation has never been safer-your students can conduct an experiment within the laboratory fume hood while collecting data at their lab station.

DC power source with a built-in current probe designed for use in electrochemistry experiments.

The Go Direct Voltage Probe combines a wide input voltage range and high precision, making it an excellent choice for investigations of both AC/DC circuits and electromagnetism.

The Go Direct Chloride Ion-Selective Electrode (ISE) is used to measure the concentration of chloride (Cl^-) in aqueous samples.

The Go Direct Optical Dissolved Oxygen Probe makes it easy to measure dissolved oxygen concentration, water temperature, and atmospheric pressure.

The Go Direct Calcium Ion-Selective Electrode (ISE) can be used to measure the concentration of calcium (Ca²⁺) in aqueous samples.

This includes Go Direct® Motion detector, Go Direct® Force and acceleration sensor, Go Direct® Voltage probe, Go Direct® Photogate, Go Direct® Current probe (2), ultra pulley attachment, picket fence, Go Direct® Acceleration sensor, Go Direct® Sound sensor, Go Direct® Light and color sensor, Go Direct® 3-Axis magnetic field sensor.

The Go Direct Gas Pressure Sensor measures the absolute pressure of a gas.

The pH Buffer Capsules (3x10) kit is a convenient set of three vials containing capsules to make pH 4, pH 7, and pH 10 buffer standards for calibrating pH sensors. Each vial contains 10 capsules, each of which produces 100 mL of solution when mixed with DI water. Add three drops of the buffer preservative to 100 mL of your buffer solution to prolong the shelf life. Hydrion Color Key Buffer Preservative is a combination mold inhibitor and universal indicator for color coding the buffer solutions: orange for pH 4, green for pH 7, and blue for pH 10.

The Dial-O-Gram is a two-beam unit that combines Dial and Vernier calibrations.

Investigate the motion of a pendulum.

The Go Direct CO₂ Gas Sensor measures gaseous carbon dioxide concentration levels, air temperature, and relative humidity.

The Go Direct Ammonium Ion-Selective Electrode (ISE) can be used to measure the concentration of ammonium (NH₄⁺) in aqueous samples.

Use the Go Direct Glass-body pH to measure pH in aqueous, heterogeneous, and organic solutions.

A powerful and versatile light sensor that measures light in the visible to ultraviolet electromagnetic spectrum.
