There are multiple types of syringes that can be used in the laboratory. Each syringe has a different purpose based on what is being performed in the lab as well as different care and cleaning techniques.

Learn about bead beating, an effective process for disrupting biological samples. This guide covers sample types, grinding media selection, processing parameters, and applications.

A cryogrinder is a laboratory mill used for grinding or homogenizing organic samples at extremely low temperatures. When analyzing a sample or material, good homogeneity of the material is essential to obtain a representative sample. Grinding and mixing is an efficient way to obtain such a result. Unfortunately, some materials are difficult or impossible to process to a homogenous form. Cryogenic grinding is a great solution for those materials.

Since its introduction in 2003 by Anastassiades and Lehotay et al, the QuEChERS method 1 (quick, easy, cheap, effective, rugged, safe) has proven to be effective and convenient for analysis of multiple pesticides in agricultural products. Increasing concern over the health effects of residual pesticides on fruits and vegetables has led to increased testing of these products to determine the levels of pesticides on produce when it goes to market. The QuEChERS method has allowed analysts to process a greater number of samples in a shorter time period than with previous methods.

Details the certification procedure for adsorption testing and typical results of Cole-Parmer's Maxisorp Microwell plates

The amount of acetonitrile found in the laboratory air was cut in half around the HPLC system on which the VapLock Closed Solvent Waste System was installed. In laboratories with multiple HPLC or LCMS systems, the reduction of indoor air pollution could be dramatically reduced ensuring the health and safety of laboratory employees.

When selecting a balance, consider the type of balance for your application, including readability and capacity; look at additional features that could offer efficiencies; and then determine how your choice fits into your budget.

A fluidized sand bath consists of a loosely packed mass of fine solid particles (aluminium oxide ) through which an upward flow of air is passed. In the fluidized state, the aluminium oxide particles become mobile, and the bath displays many of the properties of a liquid. However, since the bath is composed of tiny, inert aluminium oxide particles, any concerns related to freezing, boiling and evaporation are eliminated.

Hot plate safety is a key concern for a laboratory. Having a good understanding of the safety risks posed by hot plates and how some basic safety precautions can minimize those risks.

The Erlenmeyer flask, named after its inventor German organic chemist Emil Erlenmeyer, is also known as a conical flask or titration flask. It is used for a wide variety of applications but basically for heating and mixing solutions. Erlenmeyer flasks are crafted of many different materials including borosilicate glass, polycarbonate (PC), polypropylene (PP), polyethylene terephthalate co-polyester plastic (PETG), perfluoroalkoxy (PFA), and more.

An infrared thermometer measures temperature without contact through a point-and-click activity, which then measures temperature from black-body radiation or infrared energy produced by the material being targeted for temperature measurement.

With lab setup, design layout of how your space will function is crucial for an optimized lab. These references listed provide a wealth of detailed information. Whether you are building a new laboratory space or updating an old one, these references will help with developing good laboratory layouts that are safe and are compliant with regulations.

A lab setup project might involve building a new lab, renovating an old one, or stocking shelves. Regardless of the project, the Cole-Parmer Lab Setup Program can help you create the perfect lab space quickly.

Modern pesticides are a product of the birth of the first synthetic organic chemicals (organochloride compounds) in the late 19th and early 20th centuries. Many organochloride compounds, such as BHC and DDT, were first synthesized in the 1800s’, but their properties as insecticides were not fully discovered and exploited until the late 1930’s.
