"Tubes"

Enough materials for a complete class to perform all of the electrostatics experiments included in this set.

In this experiment, students safely analyze the enzymatic decomposition of hydrogen peroxide.

Students perform thin-layer chromatographic separation of carotene, xanthophyll, and chlorophylls.

The movement of liquid currents due to differences in temperature is demonstrated by introducing dye into the water in the tube. One corner of the tube is heated and the movement of the dye clearly establishes the currents. The rectangular shaped tube measures 15×21 cm and has an opening at the top.

Perfect for a student team.

Glows with Characteristic Brilliance!

Precalibrated test tubes and labware give fast, accurate results on-site, in the classroom, or in the lab.

Provides an Optimum Seal Every Time.

How Does Folic Acid Prevent Neural Tube Defects?

The Speed of a Bubble Set connects the mathematical concept of slope to the physical science concept of velocity.

Over 380 million people worldwide are afflicted by diabetes mellitus, a chronic disease that leads to high blood sugar. Due to genetic predisposition and high-calorie, low-activity lifestyles, that number continues to grow. Without early detection and treatment of diabetes, severe medical complications can occur. In this simulation, students will diagnose diabetes in three patients using the urine glucose test and Enzyme-linked Immunosorbent Assay (ELISA).

The 3D Magnet Viewer displays clear views of magnetic fields.

Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.

This Ballistics Cart demonstrates the independence of vertical and horizontal motions.

With the Resonance Apparatus, students investigate the effect of frequency on wavelength.
