"SCIENTIFIC HATCHERIES"

The mechanics kit for whiteboard demonstrations includes more than 25 large, colored, and easily distinguished components stored in a case with foam inlay. More than 30 experiments can be set up in rapid time. Large components ensure that experiments can be viewed from a distance. Secure attachment is guaranteed by high-grade AlNiCo magnets, allowing quick and easy configuration of experiments. Measuring units, vector diagrams, and explanations can be provided right next to the experimental configuration on the blackboard.

Digital multimeter for universal use in measuring voltage, current, resistance, frequency, capacitance, temperature and also including diode and continuity tests . Includes a measurement value hold function, analogue bar graphs, automatic polarity reversing, overload and overvoltage protection as well as an acoustic overload indicator, automatic switch off. Device comes in a shock-proof holster with fold-out stand. Including testing leads, type K temperature sensor and batteries.

Highly evacuated electron tube with focusing electron gun and fluorescent screen inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using the Helmholtz coil pair (not included). By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge (e/m) and the velocity of the electrons.

Carry out precise and efficient pouring with Polypropylene Griffin Low-Form Beakers, featuring a single-spout design and easy-to-read silk-screened graduations.

This lightweight polypropylene pump provides a constant vacuum when hooked to a standard faucet; it operates efficiently with water pressures as low as 7.5 psi for minimum water consumption. It has a maximum free-air pumping capacity of 11.5 liters per minute at a water-flow rate of 6.5 liters per minute. Ultimate vacuum: 28.5" Hg. Supplied with integral check valve, 3/8" NPT connecting thread, and 4 3/4" length of tubing for insertion in discharge end.

A steel cube, an aluminum cube and a rectangular aluminum slab have each been painted to conceal the identity of the metal. The steel and aluminum cubes have equal volume while the aluminum slab has greater volume. One plastic metric ruler is included with this set. For use with IPS textbook. Set of three.

WARNING: CHOKING HAZARD - Small parts. Not for children under 3 years.

The double junction electrode is ideal for dirty water, heavy metals, sulfides, tris buffers, and organics. The tester also features a pH and temperature readout toggle, automatic temperature compensation, and a replaceable sensor.

These uniform motion cars are a staple in the modern physics classroom.

PVC hydrometer cases help protect hydrometers from damage. These cases feature a foam or felt padded insert, and padded bottom and cap.

Keep track of lab data and results with this convenient lab notebook.

One strip of 8 related 35 mm images photographed through a microscope called photomicrographs. Arrows and call outs help the student locate important features. The film is mounted in a clear plastic holder that protects it on both sides.

Helmholtz coils are used to produce a homogeneous magnetic field. Experiments on induction and electron deflection can be performed with the Rotary Frame with Flat Coil and the Fine Beam Tube. The coils can be used in parallel or in series and feature a spring clip on the cross bar to mount a Hall Sensor for measurements of the magnetic field. The maximum field strength generated by the coils (~ 4 mT) is approximately 750 times weaker than that produced by an MRI machine (~ 3T), which are known to be safe for use by people with medical implants such as pacemakers.

These space-saving polycarbonate storage containers will withstand temperatures from –135° to 135 °C and can be autoclaved. Permanent graduations, easy-dispensing pour spouts, and leak-proof polypropylene caps also make these containers well-suited for use in the classroom, laboratory or field.

Heavy base for holding rods of up to 13 mm in diameter.

Protect skin from microbes and dryness with this antimicrobial strength soap that is extremely mild on hands.

Nalgene Complete polyetherimide jar and vacuum plate chamber provides strength and good chemical resistance.

Neoprene gasket provides secure seal. Slight amber cast of jar allows complete visibility of interior.

Plate has a center hole for exhaust with tube leading to an external hose connector which accepts 1/4" ID tubing.

For use at room temperature and at full vacuum.
