As
technology moves forward in laboratory research and development, new products
are emerging within the field of sample preparation. One of the continuously
evolving product lines is homogenizing equipment. As technology advances, the
industry will rely on novel developments within this field. Some of these
developments, offered by PRO Scientific (Oxford, CT), are described
below.
The DPS-20 dual processing system combines mechanical and ultrasonic homogenizing methods in a closed compact and timesaving unit with full automation. The system permits the use of each homogenizing method, dependently or independently of each other. It has the memory capacity to store up to nine programs at one time; alternatively, the system can be used in manual mode for individual sample processing. Users are given maximum control to best support their own processing needs.
Generator probes
Viewed as the better alternative to plastic generator probes, which are often seen as disposable, the Multi-Gen 7 is a 7-mm-diam generator probe designed to meet the ever-increasing demand to homogenize numerous samples without the risk of cross-contamination, and it eliminates the need to spend valuable time cleaning the generator between samples. The probes are designed to quickly lock into any of the manufacturer’s homogenizer units through the Multi-Gen Adapter. The adapter permits hands-free ejection of the used generator probe, which minimizes the chance of accidental contamination when attaching the next generator probe.
Responding to the needs for mechanical homogenizers that can accurately and repetitively perform batch processing, two lines of high-quality benchtop homogenizers, the D-Series and PC-Series, were developed. The slim profile of both homogenizer lines provides a more modern visual appeal, while their technological abilities are equally impressive. Each line consists of four units under the model type PRO300, PRO350, PRO400, and PRO400EL (with a convenient extra-long stand). Both series include the PRO TRAC motorized stand, which enables effortless, accurate, and smooth motor positioning. With sample volume range capability from 0.03 mL to 30 L, the homogenizers are well suited for homogenizing, emulsifying, blending, and/or mixing organic and inorganic materials.
There is currently an increasing demand to safely homogenize biohazardous materials. Safety Seal tubes and chamber assemblies were designed to provide a two-way barrier to keep both the end user and the sample safe. The assemblies protect end users from hazardous aerosols that are generated during processing. Delicate or precious samples are also carefully isolated from external contaminants. The assemblies prevent the user from operating the blade system while the blade is exposed, thus providing an additional level of safety; the tube or chamber must be assembled correctly for the generator or blade to run. The assemblies are available in tube, glass, or stainless steel, ranging from volumes of 1.5 mL to 1 L. All the assemblies work with the manufacturer’s homogenizers, from handheld to benchtop models. Safety Seal tubes and chamber assemblies are an extremely safe method of homogenizing, with either a blade for large, solid material sample processing or a rotor stator generator probe for smaller solid material or liquid processing.
