Sample Preparation Made Easy
Sample preparation is very important to obtain accurate data from analytical testing. To obtain this representative data, the entire sample must be properly comminuted. The Knife Mill PULVERISETTE 11 is perfectly suited for this task. Consistent, Representative, Accurate Consistent and viable representation of sample preparation leads to more accurate and repeatable results for analysis. Obstacles in handling or reducing materials with varied sample size, moisture levels, physical attributes, and material sensitivity create additional challenges in critical analysis. Obtaining a representative sample from an entire batch can be variable, complex, and time consuming. This is more complex when faced with a diverse sample load. While difficult, sample preparation is one of the most important steps in obtaining accurate data from analytical testing. In regards to comminution there are often limiting factors, like the rheological properties of a material, the ingredients, or the volatile components. In this case, consumer products such as blenders and coffee grinders are chosen for laboratory use. Industry quality knife mills offer specific utilization capabilities beyond consumer appliances.

Fritsch laboratory mills suitable for size reduction of latex products
Fritsch laboratory mills are suitable for size reduction of latex products, so further analyses can be done, for example for the use of solvents and toxic substances. Latex, the milk-like plant sap of the tropical rubber tree (Hevea brasiliensis), was already brought to Europe from America 500 years ago. A special property of latex is its extraordinary elasticity, which cannot be matched by any synthetic product. Protective gloves made of latex are used in the food industry, hairdressing and by cleaners. However, latex gloves can cause allergies in frequent users. To prevent allergic reactions, latex products were comminuted for further analysis in the Variable Speed Rotor Mill Pulverisette 14 premium line. Variable Speed Rotor Mill Pulverisette 14 premium line For the test, the Pulverisette 14 premium line with the cutting rotor was used. To ensure a better air flow during the comminution process, the small volume Cyclone separator was connected. The mill was operated at a speed of 20,000 rpm. The latex products were manually pre-shredded down to a feed size of 1 cm. Second step The next step was to place the pre-crushed

Quality control of nuts
Quality control of nuts
Distributors as well as consumer have a great interest in their products meeting quality standards. For chemical analysis and quality control is a diligent sample preparation as a prerequisite for a fine analysis essential, in order to observe the predefined critical values and tolerance values. Perfectly suitable for the comminution of nuts are the FRITSCH Cutting Mills. Consumer protection Food inspections concentrate on verifying harmful substances like toxins, heavy metals and non-permitted pesticides. The consumers trust that top limits of harmful substances are not exceeded and therefore contaminated products not sold. Nuts are considered a problematic product in food inspections since the shell gives no clue about whether the core has the adequate quality. The inside may contain fungal spores or toxins which simply can not be perceived from the outside. With defined methods, samples may be tested for their safety. Research and development in chemical analysis

Comminution of Nuts Generation of representative samples
Comminution of Nuts
Generation of representative samples Detailed sample preparation of nuts according to regulation (EG) no. 401/2006 with tips, approaches and photos of the individual steps With the REGULATION (EG) no. 401/2006 of the COMMISSION of 23rd February 2006 binding standards for sampling procedures and analysis methods for the official testing of the mycotoxin content of food stuffs for example nuts was established. The task in the laboratory is as follows: „Each laboratory sample is to be prepared with a verifiable procedure which guarantees a complete homogenisation, ground finely and meticulously mixed. “ The regulation allows two means: 1. The nuts in the shell may be peeled and the aflatoxin content is to be determined for the edible share. This might be still feasible for peanuts. With walnuts, filberts or almonds this is very problematic though. 2. The other possibility is to use the nuts „inside the shell“ for the sample preparation. The task: 10 kg peanuts, walnuts, filberts, Brazil nuts

Cutting Power XL for High Sample Throughput The new SM 400 XL RETSCH, a model for specific requirements
Cutting Power XL for High Sample Throughput
The new SM 400 XL RETSCH, a model for specific requirements This mill is suitable for primary cutting of large sample pieces measuring up to 170 x 220 mm, but can also achieve the required final fineness in one step, depending on the application. The grinding chamber volume of 7.5 l and the large surface of the bottom sieves (240 x 240 mm) allow for complete homogenization even of large sample volumes in one working run. Hence, the sample throughput is considerably higher than that of smaller models. Thanks to the optional cyclone-suction combination, the SM 400 XL is also suitable for grinding heat-sensitive materials. This tool not only improves material discharge but also provides a cooling effect thanks to the air jet. The fold-back hopper and removable bottom sieves ensure quick and easy cleaning of the mill. In addition to the SM 400 Xl retsch offer three cutting mill types for different requirements: from the budget-priced basic model and universally suitable standard model to the heavy-duty mill with RES technology.
