ANALYSETTE 22

NeXT Nano

PRODUCT INQUIRY

Automatic dry dispersion unit for sample volumes from less than 1 cm³ up to approx. 300 cm³ - especially suited for not too fine, free-flowing materials, which react in water or other liquids.

The ultra-compact dry dispersion unit has a height-adjustable funnel and stirrer made of stainless steel ensuring optimum sample feeding adapted to the respective sample material. All parts that come into contact with the sample can be easily dismantled - thus guaranteeing absolutely fast and easy cleaning. Also the measuring cell of the ANALYSETTE 22 NeXT can be opened without tools by means of an eccentric lock. Its cleaning is quite convenient by an easily re-insertable outer seal. And also the exchange of the measuring cell glasses can be done any time completely uncomplicated.

In dry measurement the sample material is transported with a vibratory feeder through the intake funnel into the dry measuring cell, where it falls directly into a Venturi nozzle operating with an adjustable flow of compressed air. Upon passing through the nozzle, agglomerates are broken up and the measurement of the particle size dispersion in the laser beam takes place directly afterwards.

The exhaust system, dust category "M" according to DIN EN 60335-2-69 for 230 V/1~, 50/60 Hz, 1600 Watt is versatile:

For combination with the high performance and small volume cyclones.
To operate the FRITSCH Cyclones you need an exhaust system. The strong airflow ensures simple feeding, increases throughput, and reduces the thermal load of the samples. The high performance and small volume Cyclone separator can be combined with Universal Cutting Mills PULVERISETTE 19, the Variable Speed Rotor Mill PULVERISETTE 14 premium line and classic line. The small volume cyclone can also be combined with the Variable Speed Rotor Mill PULVERISETE 14 premium line and classic line even for passive utilisation – without sample exhaust.
The high-performance cyclone is ideal for combination with the Universal Cutting Mills PULVERISETTE 19 large, the Cross Beater Mill PULVERISETTE 16 and the Disk Mill PULVERISETTE 13 premium line for optimal sample extraction and for comminution of larger quantities.

For cooling of the Variable Speed Rotor Mill PULVERISETTE 14 premium line
By connecting the exhaust system with the connecting piece order no. 14.4214.00, the cooling of the mill can easily be enhanced.

For connecting to Disk Mill PULVERISETTE 13 premium line
The exhaust is simply connected to the PULVERISETTE 13 premium line and operated via a start and stop button on the instrument – for dust free comminution.

For connecting to the Jaw Crusher PULVERISETTE 1, Modell I + II classic line
Simply connect the exhaust system to the integrated connection of the PULVERISETTE 1. Fine dust arising during comminution is automatically removed. The exhaust system is also very useful when cleaning the grinding parts.

For connecting to the Disk Mill PULVERISETTE 13 classic line
The exhaust system can be easily connected to the PULVERISETTE 13 classic line. Fine dust arising during comminution is automatically removed. The exhaust system is also very useful when cleaning the grinding parts.

For exhaustion of the sample during dry measurement with the Laser Particle Sizers ANALYSETTE 22 NeXT
An exhaust system is necessary to ensure automatic sample exhaustion during dry measurement. When the measurement is completed it can also be easily used to manually clean the feeder.

Please note that the exhaust system article no. 43.9070.00, is not equipped with a fine filter and therefore dust may escape. Please consider the valid occupational health and safety regulations. This exhaust system is mostly recommended for dust-free grinding and the vacuuming of during the process developing fine dust in the upper part of the grinding chamber and for the cleaning of the grinding parts.

For vacuuming of the sample during dry measurement with the Laser Particle Sizers ANALYSETTE 22 NeXT, we recommended we recommend the exhaust system article no. 43.9060.00, which is equipped with a hose and an ultra-fine filter of dust class "H" according to DIN EN 60335-2-69, so that the escape of fine dust is reduced.

for simple, continuous monitoring of the pH value of the dispersion liquid

The new pH sensor is installed as a module in the dispersion bath and connected to the Laser Particle Sizers ANALYSETTE 22 NeXT. It continuously measures the pH value during the measurement and automatically transfers the determined values to the software for documentation.

This method covers fluctuations much more effectively than the zeta potential and offers many advantages, especially in the area of research and development.

The pH value is much broader, especially with measurements in the field of nano-suspensions. Its monitoring provides valuable information about how and when a chemically inert material, for example, reacts to alkalis, depending on the environment. If the curve is unstable and varies during measurement, the pH value helps with stabilization and interpretation. The pH measurement process introduced by FRITSCH enables to observe these values precisely. The detection of agglomeration or aggregation is also much easier.
