AS 200 Air Jet Sieve Machine Pharma

Really robust and super sensitive: the internal balance

Comply with quality assurance standards such as ISO 9000 ff

As part of test equipment monitoring, you can calibrate the sieving machine (clock, speed & pressure sensor) and internal balance. As part of the RETSCH maintenance service, we are happy to take care of all calibration processes for you.

Thanks to native software integration, you always have control over the entire process chain via an intuitive touch display:

✔ Sieve Management
✔ Parameter Setup
✔ Method Setup
✔ Sieve Analysis
✔ Weighing
✔ Data Evaluation & Reporting via USB or LAN connection
✔ Optional User Management (in the pharma version)

Our patent, your advantage: combined sieving and weighing

The patented combination of sieving and weighing in the AS 200 jet pro offers you real added value.

The principle behind this: for sieving, the sieving chamber is connected airtight to the vacuum cleaner. For a precise weighing process, the airtight sieving chamber is mechanically decoupled.

Your advantage in everyday laboratory work: error-free, time-saving weighing and subsequent evaluation in a single process, without the hassle of transferring the sieve between the machine and the balance.

Various test sieves for your requirements – the choice is yours

Not only existing customers benefit from our modular and sustainable development design. The AS 200 jet pro allows the use of all RETSCH test sieves with a diameter of 203 mm (8″) and 200 mm (with adapter) and a height of 25 and 50 mm (1″ and 2″).

Step by step to the desired result

With the integrated software, you can easily perform both simple routine sieving and complex distribution analyses: and display all results immediately afterwards in both graphical and tabular form.

The internal wizard guides the user step by step through the entire process. Every process step is clearly explained and ensures reliable sieve processes. Human errors are reduced to a minimum.

The optional “Weighing Assistant” recommends a suitable sample amount which avoids errors based on overcharging the sieve but still keeping a minimum amount for a reliable sieve analysis by considering the sample’s representativeness.

The “Weighing Assistant” exclusively can be used with RETSCH test sieves and can easily be activated/deactivated in the method.

“TRACK’N TRACE” FOR YOUR SIEVE ANALYSIS

An integrated audit trail records all process steps and activities and assigns them to the respective users. This guarantees genuine track and trace: all user activities and events can be traced back seamlessly.

LEARN EVERYTHING YOU NEED TO KNOW ABOUT MODERN JET SIEVEING

Air jet sieving is the optimal method for dry sieving of samples with a high proportion of fine particles. Compared to traditional sieving methods, this process saves time and reduces your costs in the long term.

✔ As an alternative to vibration screening, this method offers a significantly higher process speed for fine particle sizes.

✔ Unlike other methods, air jet sieving uses only one sieve per sieving process.

The rule of thumb for choosing the best parameters:

1. Sensitive samples should be sieved with low vacuum pressure to protect the material. The vacuum pressure can be adjusted variably via the touch display. In addition, the sieve height can be varied to adjust the impact effect.
   
2. Higher vacuum pressure and/or a low test sieve are suitable for agglomerated samples. The increased impact intensity allows even strong agglomerates to be broken up in a short time.

FUNCTIONAL PRINCIPAL

The AS 200 jet pro / pharma is equipped with a rotating slot nozzle, over which the sieve and cover are placed. A vacuum generates a strong air jet that swirls the sample particles on the sieve and distributes them. Sample material that is smaller than the mesh size of the sieve is transported by the reverse air flow to the cyclone or vacuum cleaner. The air jet also ensures continuous resolution of agglomerated particles (deagglomeration) and cleaning of the sieve mesh.
