Die Rührstation ist eine Kombination aus Magnetrührer und Ringständer. Die Rührstation arbeitet effizient mit Bechern und anderen Behältern ab einer Grösse von 50 mL und einem Liter (800 mL Fassungsvermögen) zusammen. Sie arbeitet effizient mit Bechern mit einer Vielzahl von Grössen und Formen von Magnetrührstangen. Verwendet eine Closed-Loop-Drehzahlregelung, wodurch die Feinabstimmung der Rührgeschwindigkeit (50–1250 U/min) erleichtert wird.Die Rührplattform wird mit drei kühlen, weissen LEDs beleuchtet. Die LEDs sind unter der Rührplattform positioniert, um einen Glasbehälter mit Flüssigkeit hervorragend zu beleuchten.Enthält einen abnehmbaren 18" Ringständer, der bequem positioniert und am Rührersockel befestigt wird, in einer Entfernung, die die meisten Büretten- oder Utility-Klemmen problemlos aufnehmen wird.Läuft entweder mit Wechselstrom (Adapter im Lieferumfang enthalten) oder mit vier C-Batterien (nicht im Lieferumfang enthalten).Ist robust genug, um die meisten gängigen Magnetrührstäbe oder einen Vernier Microstirrer zu betreiben.Hat eine chemikalienbeständige Kunststoff-Rührplatte. Eingeschlossen: Vernier Rührstation Vernier Mikrostirrer Rührstange (4 cm) 6-Volt Gleichstromadapter Ringständer (46 cm) Bedienungsanleitung Handbuch (Englisch)

Chemistry with Vernier is the foundational chemistry book for high school and college courses. Chemistry with Vernier has more than 36 experiments in thermochemistry, gas laws, acid-base reactions, equilibrium, electrochemistry, electrolytes, states of matter, and more. Experiments are included for the Gas Pressure Sensor, Temperature Probe, pH Sensor, Conductivity Probe, Colorimeter, and Voltage Probe. If you teach Advanced Placement (AP), International Baccalaureate (IB), or college chemistry, you should also consider Advanced Chemistry with Vernier (CHEM-A) and Investigating Chemistry through Inquiry (CHEM-I).Table of ContentsExperimentSuggested Products1Endothermic and Exothermic ReactionsGo Direct® Temperature Probe2Freezing and Melting of WaterGo Direct® Temperature Probe3Another Look at Freezing TemperatureGo Direct® Temperature Probe (2)4Heat of Fusion for IceGo Direct® Temperature Probe5Find the Relationship: An Exercise in Graphing AnalysisNo probeware used6Boyle's Law: Pressure-Volume Relationship in GasesGo Direct® Gas Pressure Sensor7Pressure-Temperature Relationship in GasesGo Direct® Gas Pressure Sensor, Go Direct® Temperature Probe8Fractional DistillationGo Direct® Temperature Probe9Evaporation and Intermolecular AttractionsGo Direct® Temperature Probe (2)10Vapor Pressure of LiquidsGo Direct® Gas Pressure Sensor, Go Direct® Temperature Probe11Determining the Concentration of a Solution: Beer's LawGo Direct® Colorimeter12Effect of Temperature on Solubility of a SaltGo Direct® Temperature Probe13Properties of Solutions: Electrolytes and Non-ElectrolytesGo Direct® Conductivity Probe14Conductivity of Solutions: The Effect of ConcentrationGo Direct® Conductivity Probe15Using Freezing Point Depression to Find Molecular WeightGo Direct® Temperature Probe16Energy Content of FoodsGo Direct® Temperature Probe17Energy Content of FuelsGo Direct® Temperature Probe18Additivity of Heats of Reaction: Hess's LawGo Direct® Temperature Probe19Heat of Combustion: MagnesiumGo Direct® Temperature Probe20Chemical Equilibrium: Finding a Constant, KcGo Direct® Colorimeter21Household Acids and BasesGo Direct® pH Sensor22Acid RainGo Direct® pH Sensor23Titration Curves of Strong and Weak Acids and BasesGo Direct® pH Sensor24Acid-Base TitrationGo Direct® pH Sensor, Go Direct® Drop Counter, Precision Volume Dispenser25Titration of a Diprotic Acid: Identifying an UnknownGo Direct® pH Sensor, Go Direct® Drop Counter, Precision Volume Dispenser26Using Conductivity to Find an Equivalence PointGo Direct® Conductivity Probe, Go Direct® Drop Counter, Precision Volume Dispenser27Acid Dissociation Constant, KaGo Direct® pH Sensor28Establishing a Table of Reduction Potentials: Micro-Voltaic CellsGo Direct® Voltage Probe29Lead Storage BatteriesGo Direct® Voltage Probe30Rate Law Determination of the Crystal Violet ReactionGo Direct® Colorimeter31Time-Release Vitamin C TabletsGo Direct® pH Sensor32The Buffer in LemonadeGo Direct® pH Sensor33Determining the Free Chlorine Content of Swimming Pool WaterGo Direct® Colorimeter34Determining the Quantity of Iron in a Vitamin TabletGo Direct® Colorimeter35Determining the Phosphoric Acid Content in Soft DrinksGo Direct® pH Sensor36Microscale Acid-Base TitrationGo Direct® pH Sensor

Advanced Chemistry with Vernier has 35 advanced chemistry experiments designed for use with Vernier data-collection technology. There are four student alternative versions included for each experiment: computer, LabQuest, calculator, and a generic version that covers all platforms. Experiments are included for the Vernier Temperature Probe, pH Sensor, Conductivity Probe, Drop Counter, Colorimeter, Gas Pressure Sensor, Current Probe, ORP Sensor, and Radiation Monitor. ​Starting with the 2013–2014 school year, the AP Chemistry Course Description recommended labs have been reduced from 22 to 16 and at least six of the 16 experiments should be an inquiry-based model of instruction. Advanced Chemistry with Vernier provides a variety of experiments for the additional 10 non-inquiry experiments. Use it in addition to​ ​Vernier Chemistry Investigations for Use with AP Chemistry​ (APCHEM) ​for a comprehensive set of topics.​

This lab book provides Advanced Placement (AP) Chemistry students with 16 inquiry-based laboratory experiments aligned with the inquiry investigations published by The College Board. Each experiment guides students to investigate key principles of AP Chemistry using electronic sensors to collect important data. This lab book also provides a comprehensive set of resources for the AP Chemistry teacher, including sample data, sample analysis and calculations, and helpful guides to preparing reagents and chemical solutions. In addition, a carefully chosen set of step-by-step instructions for operating probes and software is included to help students make the best use of available lab time, while retaining the spirit of an inquiry environment.
