Product news

The ultra-compact FRITSCH Mini-Mill PULVERISETTE 23 is the ideal assistant for fine comminution of smallest quantities – for wet grinding as well as for dry or cryogenic grinding. Its special, spherical grinding bowl ensures much better performance in grinding, mixing and homogenizing compared with similar models. With a footprint of just 20 x 30 cm and a weight of 7 kg, it easily fits anywhere. It is smart, extremely user-friendly, inexpensive, and convinces with impressive results.

For perfect, loss-free grinding results in shortest times!

Ideal for
Chemical analysis: Comminution and homogenization of grinding samples for creation of compacts for x-ray fluorescence and infrared spectroscopy (e.g. potassium bromide tablets)
Environmental research: Soils in contaminant analysis, humic acid determination, botanical materials in residue analysis of fertilizers and pesticides, pulping of seeds
Pharmaceuticals and medicine: Kidney and gallstone analysis, breaking up tablets, pharmaceutical ingredients
Forensic analysis: Hair analysis for genetic testing and drug tests, preparation of extremely small particles for chemical analysis, textile fiber and bone analysis
Biotechnology: Comminution of deep frozen tissue samples
Material synthesis: Creating mixtures for catalytic tests on polymers, ceramic analysis

PTFE bowl
The 5 ml PTFE bowl is specially suited for using the FRITSCH PULVERISETTE 23 in biotechnology applications. For example, it is possible to break up fungus or yeast cells, deep frozen tissue and cells in only a few minutes with this special plastic bowl and a 10 mm steel ball. It is also possible to pre-cool the entire bowl in liquid nitrogen.


Unmatched effectiveness with spherical grinding bowls
Available only from FRITSCH: In special consideration of the ball mill grinding concept, the PULVERISETTE 23 a grinding bowl with interior walls that are spherical instead of cylindrical has been devoloped. Advantages include unmatched grinding performance with a significantly improved grinding effect, much easier recovery and simpler cleaning.

The spherical grinding bowls of the PULVERISETTE 23 are assembled simply and quickly, just twist and turn!

DNA sequencers and genetic analyzers are based on capillary electrophoresis, where labeled DNA fragments are electrophoretically separated by size as they migrate through a polymer. Find the best DNA sequencing products, including DNA sequencing kits, genomic libraries and genetic identity kits in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.NanotechnologyNanotechnology, or nanotech, is an engineering technique using molecular scale functional systems. Applications of nanotechnology include medicine and medical devices, electronics, air and water purification, food science and energy production.Evidence Collection and AnalysisEvidence Collection and Analysis is the retrieval and subsequent investigation into criminal evidence obtained from a crime scene. Forensic genetic instruments, kits and reagents enable the analysis of evidence collected  at the crime scene. Reagents and kits for presumptive analysis for body fluids such as blood, saliva and semen in addition to drugs and narcotics test kits are used for CSI. Fingerprinting equipment, forensic light sources, casting kits and equipment for collecting recoverable materials can be found in the directory.Toxicology / Drugs of Abuse TestingToxicology and Drugs of Abuse Testing is the investigation into toxic and illegal substances found at the scene of a crime or from a suspect and / or victim associated with a scene of a crime. Analyzers, immunoassays and drugs of abuse test kits and presumptive test kits are an essential aspect of toxicology investigation.Food and Beverage AnalyzersFood and Beverage Analyzers are commonly used to provide information about the chemical composition, structure and physical properties of food materials.Food and Beverage ProcessingFood and Beverage Processing involves the preparation of food products for further analysis. Typical instrumentation includes blanchers, color sorters, cookers, grinders, and refrigeration. These are used to replicate the processes commonly used in the commercial preparation of food and beverages.Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.
