Providing excellent clarity and strength, this pear-shaped funnel has a leakproof threaded screw cap. The Polypropylene stopcock, fitted with a self-lubricating PTFE plug, is push-fitted to the stem of the funnel. Not Graduated.

Store goggles, glasses, or other small lab products using the clear box. It can be used on a desktop or can be mounted on a wall. Includes a lid to keep the box free of dust or contamination.

Vividly demonstrate the interaction of a magnet and an induced current. As electrons flow in a wire, they create a magnetic field. When this current-carrying wire is near a permanent magnet it causes magnetic repulsion and motion is created. The apparatus works on 3V to 6 V DC and has a switch to...

This four-digit timer is designed to be used with air tracks, free fall apparatus, and other equipment. It is microprocessor-controlled and offers eight programmed functions to record counts, time intervals, periods of oscillation, accelerations, acceleration due to gravity, and velocities in...

Tall form clear quartz glass crucibles are ideal for applications that require ashing of samples. Quartz material offers low expansion, dimensional stability, and thermal shock resistance. Can withstand a continuous operating temperature of 1050°C (1922°F). Lids are also manufactured from quartz and...

Gooch crucibles have a perforated bottom and include lids. Crucibles are glazed on inner and outer surfaces except for the outside bottom and rim. Used for determination of total suspended solids. Thermal Shock Resistance - average coefficient of expansion from 20° C to 200° C is 3.56 x...

Precision apparatus for measuring Planck's Constant includes a mercury discharge lamp, vacuum photocell, set of mercury-line interference filters, and control unit. High quality amplifier yields results for h to better than 3%. This product has a 90 day lead time. Market standard for this type...

Large Periodic Table of the Elements measures 47" wide and 35.5" tall is easily visible from every corner of the classroom. Durable material will withstand heavy classroom use. Elements included up through UUO #118.

This kit allows students to explore the electrical properties of different combinations of electrode materials using safe, everyday chemicals such as soda, vinegar, and fruit juice as electrolytes. The set contains everything needed for the experiments except the electrolytes. Voltage, current, and...

The Loop the Loop Track demonstrates centripetal acceleration and the transformation of potential energy into kinetic energy. Included is a sturdy base with rubber feet, metal ramp with loop, 16mm steel ball and 19mm steel ball. The metal ramp with loop features a net at the end of the loop to...

This high quality model is great for anatomical study. The hand is mounted on a sturdy plastic base, and the fingers are flexible enough to demonstrate movement. Model is 8.5" tall and 4" wide.

Explore basic mechanics concepts with this all-metal, freestanding apparatus, designed for both durability and ease of use. The plane is wide enough to accommodate standard friction blocks or a Hall’s carriage with a smartphone attached, and its walled construction prevents objects from falling off...

This 400ml borosilicate glass beaker features an attached handle and a smooth rim. The molecular structure of caffeine is enamled in white on one side, and the other side has standard beaker graduations.
