Informations sur le produit "Precision Volume Dispenser"
Le distributeur volumétrique de précision offre une distribution de gouttes hautement précise et contrôlée pour les titrages automatisés. Associé à un compteur de gouttes, il améliore l'efficacité et la précision, fournissant des résultats cohérents avec moins d'erreurs par rapport aux méthodes manuelles. Il est donc idéal pour rationaliser les expériences de titrage.

Go Direct™ Drop Counter
262.90 CHF*
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
375.10 CHF*
La Stir Station est une combinaison d'agitateur magnétique et d'un support annulaire.
Le poste d'agitation manipule efficacement des béchers et d'autres contenants aussi petits que 50 mL et aussi grands qu'un litre (capacité pratique de 800 mL). Il fonctionne efficacement avec des béchers dotés d'un large éventail de tailles et de formes de barres d'agitation magnétiques.
Utilise un contrôle de vitesse en boucle fermée, ce qui facilite l'ajustement de sa vitesse d'agitation (50–1250 tr/min).La plate-forme d'agitation est éclairée par trois DEL blanches fraîches. Les DEL sont placées sous la plate-forme d'agitation pour fournir un excellent éclairage d'un récipient en verre contenant du liquide.Comprend un poteau annulaire amovible de 18" idéalement positionné et fixé à la base de l'agitateur, à une distance qui s'accommode facilement de la plupart des pinces buret ou utilitaires.Fonctionne avec alimentation CA (adaptateur inclus) ou quatre piles C (non incluses).Suffisamment robuste pour faire fonctionner la plupart des barres magnétiques de taille courante ou un Microstirrer Vernier.Possède une plaque d'agitation en plastique résistant aux produits chimiques.

83.40 CHF*
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

83.40 CHF*
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
120.20 CHF*
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.
