Go Direct™ Drop Counter
CHF 262.90*
The Go Direct Drop Counter precisely records the number of drops of titrant added during a titration and then automatically converts it to volume. It directly connects wirelessly via Bluetooth® or wired via USB to your platform.
Conducting a titration has never been easier. Use Go Direct Drop Counter in conjunction with our other Go Direct sensors, such as Go Direct pH, Go Direct Conductivity, or Go Direct ORP, to perform acid-base, conductometric, or potentiometric titrations.
Designed with a wide drop-detecting area, Go Direct Drop Counter removes the need for precise burette alignment. We’ve also included a large sensor slot for conventional stick-style sensors and a smaller, adjustable slot for temperature probes. The adjustable clamp easily fits our Stir Station and most laboratory ring stands and lattices.
Specifications:
Accurate drop counting at rates up to 6 drops/s
Dimensions:
Opening for drops: 3 cm
Openings for sensors (diameter): 7 mm and 13 mm
Ring stand opening: 16 mm
Total length: 15.5 cm, width: 4.5 cm, height: 1.8 cm

Stir Station
CHF 375.10*
La Stir Station è un agitatore magnetico combinato con un supporto ad anello.
La stazione di mescolamento gestisce in modo efficiente becher e altri contenitori da 50 mL e da un litro (800 mL di capacità pratica). Funziona in modo efficiente con becher con un'ampia gamma di dimensioni e forme di barre di mescolamento magnetico.
Utilizza un controllo della velocità ad anello chiuso, facilitando così la regolazione della velocità di agitazione (50-1250 RPM).La piattaforma di agitazione è illuminata da tre LED bianchi freddi. I LED sono posizionati sotto la piattaforma di agitazione per fornire un'ottima illuminazione di un contenitore di vetro di liquido.Include un supporto ad anello da 18 pollici rimovibile comodamente posizionato e fissato alla base dell'agitatore, ad una distanza tale da ospitare facilmente la maggior parte dei morsetti di servizio.Funziona con alimentazione AC (adattatore incluso) o con quattro batterie C (non incluse).È sufficientemente robusto per azionare la maggior parte delle barre di agitazione magnetiche di dimensioni comuni o un Microstirrer Vernier.Ha una piastra di mescolamento in plastica resistente alle sostanze chimiche.
Inclusi:
Stazione di Vernier Stir
Microagitatore Vernier
Barra di agitazione (4 cm)
Adattatore di alimentazione DC da 6 volt
Supporto ad anello (46 cm)

Chemistry with Vernier
Da
CHF 83.40*
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).
Advanced Chemistry with Vernier
Da
CHF 83.40*
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.
Vernier Chemistry Investigations for Use with AP* Chemistry - Print and E-Book
CHF 120.20*
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.
