Tamiseuse à jet d’air AS 200 Jet pro / pharma Improved process reliability

Contrôle des tamis – le chemin direct vers le bon tamis grâce au code-barres

Assurez-vous que le tamis d'essai correspond à la méthode sélectionnée et identifiez vos échantillons en scannant simplement le code-barres correspondant ! Grâce à un lecteur de codes-barres USB standard et à l'option Sieve-Check (Controle des tamis), vous pouvez vérifier la compatibilité entre la méthode sélectionnée et le tamis d'essai requis. Cela réduit le risque d'erreurs à long terme.

The digital Weighing-Assistant

Determining adequate sample quantities is a real time-consuming task, especially when dealing with different sample materials in series.

• Overloading the sieve leads to non-reproducible sieving results, as the sample cannot be sieved (quickly enough).
• Insufficient sample quantities lead to incorrect results, as their representativeness cannot be guaranteed.

Thanks to the new Weighing-Assistant in the AS 200 jet pro, this problem is now a thing of the past. After entering the respective sample bulk density, the system recommends a sieve-specific weighing range. This allows you to meet the specifications for the maximum permissible sieve load and the required minimum quantity in equal measure – and avoid incorrect sieving!

Weigh-In-Tolerance

This function allows you to set your own parameters for your individual weighing processes. First, specify the sample quantity to be weighed. Then you can define define deviation tolerances as upper and/or lower limit in percent. Compared to the Weighing-Assistant (which refers to general standards), a narrower process-related loading range can be specified—tailored precisely to your needs.

Tolérance de pesée arrière

Votre échantillon respecte-t-il les limites de qualité prédéfinies ? Grâce à la tolérance de pesée, vous pouvez vous assurer que la taille des particules et leur distribution répondent à vos exigences.

• Tout d'abord, utilisez la fonction « Weigh-In-Tolerance » (Tolérance de pesée) pour peser l'échantillon avec précision.
• Avec la tolérance de poids arrière, vous pouvez également définir le poids arrière attendu (en surpoids ou en sous-poids) en grammes.
• Vous pouvez définir un écart en pourcentage pour ajuster la plage de tolérance autorisée.

Les écarts par rapport aux spécifications apparaissent immédiatement sous forme de message à l'écran, ce qui vous garantit une fiabilité encore plus grande du processus !

Trend analysis: Test equipment and process monitoring -
Proactively avoid incorrect sieving

Trend analysis can be used to compare several sieving processes based on freely selectable parameters. This allows you to benefit from simple and reliable monitoring of various quality criteria.

Test equipment monitoring

Detect early on when your sieves are no longer functioning in accordance with standards and need to be replaced.

• Blinding refers to a wear process in which the sieve mesh becomes clogged with particles.
• Aging processes and wear-promoting handling in the often-hectic everyday laboratory routine lead to a decrease in sieve tension or an expansion of the sieve meshes on the material side.

Replace the often purely subjective assessments with objective measurement data that realistically reflects the current condition of your sieve. Trend analysis allows changes in sieve quality to be detected and faulty sieves to be replaced at an early stage. For certified sieve testing we offer the Retsch calibration service.

Process monitoring

Monitor production processes change by continuously comparing multiple sieving processes. This allows you to identify potential changes in ongoing processes at an early stage and make immediate adjustments.

Tamiseuse à jet d’air AS 200 Jet pro / pharma Learn everything you need to know about modern air jet sieving

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.

Guided Sieving: After selecting the desired sieving method, the software guides you step by step through the sieving process. You can precisely control all relevant parameters via the control panel of the AS 200 jet pro. In addition, Guided sieving improves safety, as each step is clearly described, thereby reducing human error.

• The speed of the nozzle influences the frequency of impact of the sample during the sieving process.
• The vacuum has a significant influence on the sieving process and can be controlled by automatic vacuum cleaner control.
• The sieving time can be set to the nearest second.
