Laser Particle Sizer

ANALYSETTE 22

NeXT Micro

Automatic particle size analysis: unbeatably simple and affordable

The completely revised ANALYSETTE 22 NeXT Micro with a measuring range of 0.5 – 1500 μm is perfectly suited for all measuring tasks. The intelligently revised measurement design makes the ANALYSETTE 22 NeXT especially compact and space saving. The measuring time is for most measurements less than a minute – including a reliably residue-free cleaning.

The complete evaluation of the particle size analysis takes place automatically with clearly organised results visible directly on the screen. Of course, you can also save and print out a report customised to your needs. 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.

The ANALYSETTE 22 NeXT Micro is ideal for especially efficient particle size analysis – in production and quality control as well as in research and development or for controlling manufacturing processes.

Certified reproducibility
The ISO 13320 (Particle size analysis – Laser diffraction methods) defines as a guideline the minimum standards for Laser Particle Sizers regarding repeatability, reproducibility and measuring precision and thus regulates the verification of the measuring results. The FRITSCH ANALYSETTE 22 NeXT clearly surpasses the requirements of the ISO 13320.

The FRITSCH patent
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. Your advantage: No additional optical elements are necessary between the measuring cell and detector. The design is compact with as few components as possible and has no moving parts – low wear and practically maintenance-free.

Strong advantages during measurement
• Only one light source: simple, robust, reliable
• Quick and simultaneous recording of all scattering data
• Highly precise recording of the light intensities by state-of-the-art 16 bit converter technology
• Recording also of very wide scattering angles by intelligent measuring cell design
• Two models available with different measuring ranges
• Continuous logging of the laser output
• Quick, automatic beam adjustment

One laser – faster measurement
The ANALYSETTE 22 NeXT operates with only one laser. Therefore it records the entire measuring range with only one scan. That makes your work significantly faster – you can conduct more measurements in the same time if necessary. And see live how the measuring result develops.

Extremely enlarged measuring angle
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.

Simultaneous data acquisition
Due 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. 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.

Reliable thoroughness
For most samples, wet dispersion represents the ideal method of preparation for particle size measurement. What counts here: Each particle size measurement is only as good as its dispersion. For this reason, we place great importance on this aspect and bring all our experience to bear. The result: a quite powerful, flexible and modular wet dispersion system.

A powerful centrifugal pump with individually adjustable speed ensures stable measuring in the dispersion unit of the ANALYSETTE 22 NeXT. It also transports heavy particles and facilitates a fast and uniform distribution of the sample material in the entire circulation system. Standard programs for simple operation, freely programmable dispersion process, an especially fast and efficient automatic cleaning and many other advantages also simplify your work. And ensure the quality of your measuring results.

Fast measurement of powdery samples in an accelerated airflow
Dry dispersion is especially suited for not too fine, free-flowing materials, which react in water or other liquids. For sample volumes from less than 1 cm³ up to approx. 300 cm³.

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.

Work particularly easily with the FRITSCH wet dispersion unit
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. A single rinse is sufficient and you can go on directly to the next sample.

Easily removable hood
The hood of the FRITSCH wet dispersion unit can be removed quite easily. This makes the complete dispersion bath much more accessible for cleaning than comparable instruments.

Dispersion bath without dead space
Available only from FRITSCH: The first fully automatic wet dispersion unit that does not need a clamping or rotation valve for emptying the system. That makes it significantly more robust and virtually wear-free. And there are neither difficult to clean dead spaces in which soiling can get deposited permanently nor seals that can become leaky just by single particles.

Easy visible hoses
The hoses made of silicone with especially smooth interior surfaces are hardly susceptible to deposits and make soiling or blockages directly visible. Due to practical cap nuts they can be easily removed and reattached manually without tools for cleaning.

Predefined SOPs make the operations especially easy
The ANALYSETTE 22 NeXT software contains completely predefined Standard Operating Procedures – SOPs for short – for nearly all typical measurement tasks, making operation especially easy. Via a well-arranged input mask, you are completely free and flexible in modifying these SOPs to perfectly suit your measurement requirements.

By selecting a predefined SOP, for example, dispersion process and duration, measuring frequency and time intervals are set automatically. For flexible adjustment you can also freely select it and many other parameters, save it as a separate SOP and retrieve it at any time. Your advantage: a completely new level of freedom in designing and structuring the entire dispersion and measurement process. And simple, reliable reproducibility of the measurement sequence.

Security by individual user rights
The individual assignment of user rights allows you to define precisely for the user the access to data or the ability to influence measurement processes.

For the control, recording and perfect evaluation of your measuring results your ANALYSETTE 22 NeXT is delivered with the software MaS control software in which all user entries, parameters and results are saved automatically and revision-proof in an SQL database. And by integration into a local computer network, all measuring data can also be conveniently analysed on other computers.
