Lab Equipment: Test Your Knowledge of Refractometers

Imagen
An essential piece of lab equipment is the refractometer, which measures sugar content in liquids. Chances are, around the holidays your intake of sugar increases. From pumpkin or pecan pie to holiday cookies to chocolate, the availability of sweet treats seems neverending. How much sugar is actually in that cranberry sauce? Is there sugar in the gravy that spills over those mashed potatoes? How about the yams? Low-Cost Brix Refractometer with ATC, 0 to 32% Refractometers use Brix degrees to indicate the amount of sucrose in the solution. How much do you know about the various types of refractometers? Take the Tech Challenge below! Tech Challenge! Candice at Candy Coats has decided to start a quality control laboratory to standardize and monitor their candy products for consistency as they expand and produce more. She would like to test a sample of each finished batch of soft and hard candies for the refractive index (RI) in order to measure of the sugar content specificall

Lab Equipment: Five Characteristics for Choosing Stirrers and Hot Plates

Imagen
When choosing lab equipment such as hot plates, stirrers, and stirring hot plates, consider the following five variables: Cole-Parmer® Nine-Position Stirring Hot Plate Accuracy and Stability : Basic analog heating and stirring units do not provide exact temperature or stirring speed control. However, they do offer economy, reliability, and ease of use when precise control is not required. Units with demand-type bimetallic thermostats that sense changes in top plate temperature through a mechanical connection offer somewhat better heat control. These units simulate closed-loop control and minimize temperature overshoot. Digital heating and stirring equipment with electronic feedback controls offer the greatest degree of accuracy and stability and are recommended for applications in which the control of temperature and stirring speed is crucial—with heat control stability better than ±8°C and stirring speed and control better than ±20 rpm. A closed-loop PID microprocessor con

Take the Masterflex Challenge

Imagen
Masterflex ®  pumps can be used for a variety of applications: pharmaceutical, research & development, manufacturing, food & beverage, and environmental uses. Yet, sometimes the challenge is to choose the correct Masterflex pump, pump head, and tubing to best match a particular application. Here is one scenario: Challenge:  An agricultural company needed to pump ethanol at approximately 7 LPM to a stripping column. They needed a pump drive that would withstand the flammability of ethanol and tubing that provided excellent chemical compatibility. Our solution:  Our   Application Specialist recommended the I/P ® hazardous-duty pump drive and Viton ®  tubing. The I/P hazardous-duty drive is UL-listed for Class 1, Group D, Division 1 hazardous locations. The Easy-Load ®  pump head provides greater flow rate flexibility if the customer needs to use other sizes of tubing. With respect to the tubing, Viton has an excellent chemical compatibility rating with ethanol. Select

What’s In It? Find Out with Refractometers, the Most Versatile of Lab Equipment

Imagen
ATAGO Digital Pocket Refractometer Quick quiz: What item of lab equipment can be found in a mechanic's toolbox, a winery, and even a gemologist's desk? This resourceful device can also be used by labs to conduct drug testing, but is most often used in the food and beverage industry. Of course, it's the  refractometer , which is so versatile it can test everything from battery acid to the authenticity of emeralds. Both home beer brewers and aquarium keepers rely on a refractometer for very different purposes. The refractometer requires only a few drops of liquid to measure concentrations of aqueous solutions. Solutions have different refractive indexes depending on their concentration and a refractometer can measure the purity of the composition of the solution. For example, a Brix refractometer can determine the amount of sucrose in fruit juice for quality analysis. Different types of refractometers can measure gases and translucent solids. Most models feature Automat

Lab Equipment and Efficiency: How Data Loggers Can Save Hours

Imagen
Once upon a time in the history of lab equipment, chart recorders logged data inputs using several different inks on circular charts or strip charts. They monitored environmental conditions such as temperature and humidity and provided visual feedback to assess trends. Specific field applications—or situations in which computer access is not available—may still rely on this technology. However, it has largely been replaced by the easy-to-use and economical data logger. Data loggers record properties including temperature, barometric pressure, humidity, carbon monoxide, water levels, and/or processes. Some units are designed for documenting dynamic environments such as moving vehicles, trucks, containers, ships, and more. Others log voltage and current in industrial processes, productivity checks, and troubleshooting. The common element in all data loggers is the ability to track, record, and in most cases, download or export readings to a computer. Although the expense involved i

Using a pH Meter to Test Wastewater

Imagen
Excessive pH levels, particulates, and contaminants are typically found in wastewater. Using pH in wastewater treatment requires an accurate and robust measurement with a   pH meter . It also necessitates the measurement of the water's temperature. Because chemical and particulate contamination in wastewater can destroy standard pH electrodes, prematurely killing the junction, specialized pH electrodes are recommended. A double junction electrode will block chemical interferences in the wastewater, and prevent common chemical damages to the reference junction. A flushable junction will handle chemical and particulates in the wastewater easily. A flushable junction is ideal for sludge, paper-pulp, and dirty samples as the easy-to-clean junction never clogs. Testing the pH of a Wastewater Sample Oakton® pH 5+ Meter with Probe What's Needed:  A standard pH meter, a durable pH electrode, an automatic temperature compensation (ATC) probe, a stirrer with stir bar, 100-mL gr
