    Melting Point Apparatus, Cole-Parmer Stuart MP-100

    The MP-100 measures the melting point of chemicals from ambient to 250°C. Samples need to be placed in a sealed end capillary tube and located in the heating block. Up to three tubes can be tested at one time. The heating rate can be adjusted manually between 1 to 20°C/min, and for rapid heating 10°C/min, to obtain an accurate melting point range. The sample and melt process can be viewed via the magnifying lens, which is illuminated by bright LEDs. Record the melt temperatures from the thermometer, positioned horizontal to the samples to allow simultaneous viewing. The lens can be detached for cleaning and simple to follow instructions are printed directly on to the unit, making it easy for students to use. For 220/240V. Dimensions (L x W x H): 370 x 140 x 110 mm.

    Ion Exchange Chromatography Kit

    Most molecules have net charge within pH range of 2 to 10. When the pH is altered, the net charge on molecules can change drastically. In this experiment, mixture of two chemicals is absorbed onto solid support ion-exchange column and separated during elution under conditions that influence their net charge. Kit includes: instructions, ion exchanger, chemical mixture, potassium acetate buffer, chromatography columns. • All you need: spectrophotometer cuvettes, ring stands and clamps, test tubes, lab glassware, distilled water, ml pipets and pumps. For 6 Separations. Requires 60-90 min.

    Mole Set

    This Mole Set contains samples of four different metals and helps students to visualise mole of substance in solid state, as well as developing better understanding of the concept of the mole, mass, molar mass, along with the differing properties of the various metals. The set contains four element specimens: copper, iron, zinc and aluminium, each containing approximately one mole (6.023 1023 atoms) of the element. Comparison of each sample, side-by-side, clearly shows that the same molar amount of different elements have different masses and occupy different volumes, due to each element having different atomic mass and density.
