A single rinse is sufficient and you can go on directly to the next sample. The efficient, valveless rinsing of the FRITSCH wet dispersion unit utilises the powerful pressure of the pump and thus achieves a fast and thorough cleaning of the dispersion system. Work particularly easily with the FRITSCH wet dispersion unit 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.ĭETAILS on the modules in the leaflet 'NEW INSPIRATIONS FOR YOUR lab' 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. And also the exchange of the measuring cell glasses can be done any time completely uncomplicated. Its cleaning is quite convenient by an easily re-insertable outer seal.

Also the measuring cell of the ANALYSETTE 22 NeXT can be opened without tools by means of an eccentric lock. 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.Īll parts that come into contact with the sample can be easily dismantled - thus guaranteeing absolutely fast and easy cleaning. For sample volumes from less than 1 cm 3 up to approx. As a result, it always delivers the entire scattered light distribution at respectively exactly the same time and transmits it several hundred times per second to the software.įast measurement of powdery samples in an accelerated airflowĭry dispersion is especially suited for not too fine, free-flowing materials, which react in water or other liquids. That is the decisive difference especially in the nano range.ĭue to its ultra-modern electronics, whose core are extremely fast, high-resolution converters, the ANALYSETTE 22 NeXT records the signals of all detector elements simultaneously. In the ANALYSETTE 22 NeXT, the measuring cell is set at an angle to the laser beam so that a significantly wider scattering angle range can be recorded as with comparable instruments. And see live how the measuring result develops.

That makes your work significantly faster – you can conduct more measurements in the same time if necessary. Therefore it records the entire measuring range with only one scan. The ANALYSETTE 22 NeXT operates with only one laser and does not need an additional light source even for backward scattering. Two models available with different measuring ranges.Recording also of very wide scattering angles by intelligent measuring cell design.Highly precise recording of the light intensities by state-of-the-art 16 bit converter technology.Quick and simultaneous recording of all scattering data.Only one light source: simple, robust, reliable.The design is compact with as few components as possible and has no moving parts – low wear and practically maintenance-free. Your advantage: No additional optical elements are necessary between the measuring cell and detector. The current generation ANALYSETTE 22 NeXT operates like every FRITSCH Laser Particle Sizer to date with the Reverse Fourier design invented by FRITSCH which has established itself by now as a general standard. Get all the decisive advantages with the model that meets your requirements: especially easy operation and cleaning, short analysis times, reliably reproducible results and the recording of additional parameters such as temperature and pH value during wet dispersion. Of course, you can also save and print out a report customised to your needs.

The complete evaluation of the particle size analysis takes place automatically with clearly organised results visible directly on the screen. The measuring time is for most measurements less than a minute – including a reliably residue-free cleaning. The intelligently revised measurement design makes the ANALYSETTE 22 NeXT especially compact and space saving. The completely revised ANALYSETTE 22 NeXT Nano with an extra wide measuring range of 0.01 – 3800 μm for maximum precision and sensitivity for smallest particles with an additional detector system. Automatic particle size analysis down to the nano-range: unbeatably simple and affordable
