Easy way to test plant samples for their required macronutrients.

This star fish model depicts internal structures, including the digestive and reproductive organs, as well as the radial nerves for detailed examination.

Backpack Lab designed for educators and environmental science students, containing lessons, activities, and test kits that relate to important parameters evaluated in soil quality. 

Pre-mixed, and ready to use, this master mix contains DNA polymerase, dNTPs, MgCl₂, and reaction buffers at optimal concentrations for the amplification of DNA via PCR. Its special formulation allows for direct loading of PCR samples into agarose gels as well as tracking the migration during electrophoresis without the need for loading dyes. Simply add template, primers, and nuclease-free water, available separately. Mater Mix reduces risk of contamination. Includes enough for 100 reactions. Note: Can be stored at 4 °C for up to six weeks, or −20 °C for longer.

Easy way to test soil for the macronutrients that grow healthy plants.

Decon's phenazine paper is specifically designed for determining pH in the range of 4.0 to 8.0.

This chemical test kit will determine the commonly monitored parameters in soil testing.

Ideal for Showing Archimedes’ Principle

Practice more advanced examination techniques.

Demonstrate the Stirling Design External Combustion Engine with our 18×11 cm working model. The Stirling engine currently is being re-examined as a practical source of power because of its adaptability to almost any fuel. First produced in the 1800’s as a non-electric fan and an automatic hot air water pump, the engine soon became obsolete due to its lack of sufficient power when compared to the newly developed combustion engine. Any fuel can be used with our model, but denatured alcohol is suggested for clean operation.

Simplify soil nutrient testing with reliable, pre-measured tablets. Ideal for hands-on classroom labs and field soil analysis.

High Quality for the Classroom.

This non-clogging aspirator head prevents large debris from entering and clogging the system.

Ultra-thin, comfortable, and breathable.

More bubbles are more fun.

These reagents are the replacement reagents for the total chlorine checker® HC. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.
