Refill for The Comprehensive Water Monitoring Kit 470004-240 and LaMotte® TesTab® Water Investigation Kit 470007-270

Use gel electrophoresis to compare DNA fingerprints from the shark attacks and determine if a single shark is to blame.

Explore the carbon cycle by simulating the production of carbon dioxide due to microorganisms in soil.

This chemical test kit for the determination of six parameters commonly monitored for aquaculture testing: alkalinity, carbon dioxide, hardness, dissolved oxygen, pH, and salinity. This kit is equipped with all the necessary reagents and equipment to perform over 100 tests for each parameter. pH is obtained with Hanna's pH tester, which guarantees greater accuracy and a longer life than traditional litmus paper.

The handheld refractometer is exceptionally simple to operate and provides quick, accurate measurements for the concentration of nearly any aqueous solution in a wide range of applications.

ReadyStrain™ is the first product of its kind, providing all the necessary parts for filtration of cell suspensions and combining them into a single, pre-assembled, ready to use, sterile packet.

Pivot, Grip, and Explore Range of Motion with Hydraulics

The handheld DEF (Urea) refractometer features the largest, easiest-to-read scale available with clear, sharp figures, screen shading and incredible contrast. This significantly enhances overall precision, even when several different people use the refractometer.

Astronauts aboard the International Space Station (ISS) need your help protecting themselves from disease-causing bacteria!

Make teaching diffusion easy. Exclusively from Ward's Science, we've pre-mixed, pre-poured, pre-measured and pre-cut these agar cubes to save you time and eliminate messy preparation in your lab. Just open the jar and begin using. Prepared to align with Ward's AP Biology Investigation 4: Diffusion and Osmosis, these cubes are also ideal for use on their own, or in any lab activity demonstrating the topic of diffusion. Agar cubes are prepared in three sizes (approximately 1cm, 2cm, and 3 cm). Phenolphthalein has been added to the cubes to exhibit a vivid fuchsia color during production and stored in a solution of sodium hydroxide. Just add an acid such as vinegar to demonstrate diffusion.
