Hot Plate, Flinn, 4" x 4"
The Flinn Hot Plate is a state-of-the-art device. The space-age ceramic top has excellent chemical resistance, high impact strength and an unsurpassed flat surface. Ideal for heat transfer. An electrical input controller provides fine temperature control from ambient temperature to 538 oC. You can reach a rapid boil in just eight minutes! The square top is isolated from the die-cast aluminum base so your laboratory bench tops are protected against heat damage. The heating elements are embedded in
the ceramic top so no exposed or glowing heating elements are present. Integral ring- stand holder accommodates 1⁄2" diameter support rod (Flinn Catalog No. AP8228). Electrical requirements: 120 volts, 3.2 amps, 385 watts. Maximum temperature: 538 oC (1004 oF).
AP9806 I $285.00
Hydrion 1–12 pH Test Strips
A low cost vial of pH paper (in strips) that covers the full range of 1 to 12 pH units. A color change will occur for each pH unit, and a color-matching chart is affixed to the side of the vial. Two charts are provided on each vial (1–6 pH and 7–12 pH). 100 strips per vial. Consider this paper as a substitute for traditional litmus paper. Although the cost is approximately three times that of litmus paper, the sharply defined color for each pH unit will provide the student with more accuracy than just acid or base as with litmus paper.
AP1107 I $2.10
Beakers, Borosilicate Glass
This is your basic beaker. Enamel gradua- tions. All sizes have an extra-large marking spot. The 50-mL through 4-L size borosil- icate glass beakers are graduated, metric scale, to indicate approximate volume.
10 options available at flinnsci.com $3.45–$75.15
Spirit-Filled Thermometer, –20 to 110 0C, Partial Immersion
A safer, non-mercury alternative. While these instruments are not as accurate as mercury-filled thermometers, they are “good enough” considering the hazards posed by mercury contamination. Available as partial or total immersion. 12" long with 1 oC subdivisions. To prevent column sepa- ration, always store in an upright position.
AP1452 I $6.25 Great tools for carrying out
chemical reactions!
