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 pieces in a suitable vessel and embrittle them with liquid nitrogen N2. Sieve shells with trapezoidal perforation 1 mm in the cutting rotor were used. The crushed sample was collected in the collecting vessel and the sample glass of the small volume Cyclone separator. The small volume cyclone was used passively without a vacuum.
The trapezoidal perforation of the sieve shells < 1 mm used in the cutting rotor were completely residue-free the after comminution and not clogged. Finally, the latex sample was packed for further use.
