How Lab Homogenizers Contribute to R&D

Some of us may remember grandma with the spoon and bowl or mom with the Mixmaster but for R&D scientists this mixing action is accomplished by using lab homogenizers.  These compact but immeasurably useful benchtop instruments are used to develop scalable processes for processing ingredients – some of which may be initially incompatible – into…

Flow-through Chamber Accessory for a Lab Homogenizer

Lab homogenizers are often the instruments of choice when developing pilot-plant procedures to be scaled up to production line operations. Typically laboratory homogenizers are suspended over beakers or flasks containing samples to be processed by being drawn into the homogenizer generator for mixing, dispersing, emulsifying and similar treatment. Researchers can greatly extend the utility of…

Cleaning and Sterilizing Laboratory Homogenizers

As with medical and surgical instruments, laboratory homogenizers must be thoroughly cleaned and sterilized or disinfected after use to avoid contaminating subsequent samples. The complex designs of homogenizer rotor-stator generator teeth and slots provide an ideal setting to trap and hold sample particles. Here we present a suggested procedure that can be employed or modified…

Understanding Laboratory Homogenizers

A lab homogenizer is often the tool of choice for researchers in pilot plant labs to develop procedures aimed at achieving the most efficient method of processing samples that later can be applied to full-scale production lines.  These versatile tools are fitted with what are called rotor-stator assemblies  powered by a drive motor, much in…

Achieve Superfine Disintegration with a High-Speed Homogenizer

Superfine disintegration in samples from 0.l ml to 2 liters in volume is achieved by using high-speed lab homogenizers such as the X360 offered by CAT Scientific. With a design speed of 45,000 RPM the 350-watt drive motor can be mated to rotor-stator generators in 6 sizes from 6 to 40mm in diameter and Teflon…

How to Prepare Linen for Radiocarbon Dating

Radiocarbon dating is a common technique to determine the age of a sample.  Dating ancient linen samples such as found, for example, on mummy shrouds is a complex process involving cleaning the sample to remove neutron contamination on the external layers of the fiber.  Such contamination skew results and can occur over the years from…

Homogenizer Configurations for In-Line Processing

Lab homogenizers are versatile tools used to mix, emulsify, disperse, disrupt and otherwise subject materials to a violent action by passing them through what is called a rotor-stator generator.  For simplification we’ll say that homogenizers “mix.” Rotors are powered by a drive motor, most of which have controllable speeds.   The processing end of the rotor…

When to use Sealed and Non-Sealed Homogenizer Shafts

Laboratory homogenizer shaft assemblies have a number of components, all designed to work together to accomplish homogenizing, emulsifying, mixing, cell disruption, and similar processing.   The work performed governs the selection of the homogenizer generator, specifically choosing the correct rotor-stator configuration.  This includes the size (diameter) and the length of the shaft assembly. For certain homogenizing…
