For use with electrovoltaic cells or in various other chemical, physics and chemistry experiments. Each metal electrode measures about 120mm x 18mm x 0.75mm (5" x 1/2" x 1/32"). Metals include Iron, Copper, Zinc, Brass, Aluminum, Bronze, Steel and Magnesium.
WARNING: Metal electrodes have sharp edges. Not a toy!. Handle with care.

For qualitative and quantitative study of the electrolytic decomposition of electrolytes such as water, hydrochloric acid etc. Consists of two vertical 50mL, gas-collecting, graduated glass tubes with stopcocks at top and joined by a bridging tube to a reservoir. Works with matching graphite electrodes or platinum electrodes that may be fitted at the lower ends of the glass tubes. Packed in a styrofoam case. Mounted on a cast iron stand designed for safe clamping. Requires a 6V battery or low voltage D.C. power supply for operation.

For use with Hoffman Electrolysis Apparatus described above. Size (l x d), 100 x 5mm. Inserted in a rubber stopper with insulated lead wire.

This wooden clamp can be used for tubes from 10mm to 19mm. With a steel spring. Jaws open by thumb presure. Smooth finish. Length about 180mm

Set of 6 plastic beakers molded of translucent Polypropylene plastic, with raised numerical graduations on the outside. Resistant to most common acids, bases and solvents. Has a broad base for stability. All sizes have pouring spouts. Does not have meniscus. Autoclavable to 130 degrees C. This set includes one each of 50ml, 100ml, 250ml, 500ml, 1000ml, and 2000ml beakers.

Sizes from 1 mL to 25 mL have unique smooth one-piece construction. There are no seams at the mouthpiece or tip ends, thus no possibility of sample hang-up or accidental breakage due to irregularities or weakness. One-piece construction pipete also provides improved accuracy with calibration to deliver at ±1.5%.
Sterile, Individually Wrapped.
