"Sample+Dippers"

Borosilicate glass vacuum desiccator, fitted with a stopcock and porcelain desiccator plate, allowing controlled moisture and gas removal, ideal for laboratory experiments and sample storage.

Features one scoop end and one flat spatula end. Designed for use with small samples. Perfect for a variety of laboratory uses.

Compact unit to record industrial events, receive lab samples, take surveys, inventory items, total drops of liquid, count occurrences, and more. Made of metal for reliability, long life, and hard use. The rugged, heavy-duty chrome-finished case has a hinged finger loop for a sure grip.

Use the Turbidity sensor to measure the turbidity of freshwater or seawater samples. Its small, sleek design and simple setup make it easy to use at the collection site or when you return to the classroom.

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

The test kits utilize CHEMetrics Titrets® ampoules. Titrets ampoules use a reverse titration technique to measure analyte concentration levels (titrant volume inside the ampoule is fixed while the sample volume is varied).

Stabilize the fine structural details of tissue samples with this histology-grade formaldehyde fixative.

Clearly visualize the mitochandria of cells in histological tissue samples with this 1% janus green solution.

The NED method is widely used in the quantitative analysis of nitrite and nitrate in water samples. NED readily undergoes a diazonium coupling reaction in the presence of nitrite to give a strongly colored pink azo compound. The intensity of the color is directly proportional to the concentration of nitrite in the sample. Due to the significant intensity of the developed color even at very low nitrite/nitrate concentrations, lower detection limits and measurement ranges are possible vs. chromotropic acid kits. In addition, the nitrate measurement uses only zinc which is less toxic than cadmium, making handling and disposal safer.

Clearly differentiate between cell and tissue types in histological samples with 1% neutral red.

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

Conical centrifuge tube made of borosilicate glass with a 15 ml capacity, featuring 0.2 ml graduations, and equipped with a screw cap for secure sealing and precise sample containment.

Test your student's geology skills with this educational and fun activity. Students receive a bag of unlabeled rock specimens, then must test for physical and chemical properties in order to identify each rock sample. The easy-to-follow flowchart aids students in their classification decisions.

Transect tape provides K-12 students with a simple, hands-on tool to explore scientific sampling, spatial measurement, and biodiversity observation, fostering real-world inquiry and data collection skills.

Use hematoxylin in tandem with Eosin Y or to visualize DNA and RNA in histological samples.

Test tubes and everything you need to use them.
