Atomic Absorption Spectrophotometer | Flame & Graphite Furnace AAS TAS990

Designed for research institutions, pilot plants, and quality control laboratories, this vertical semi-circular planetary ball mill delivers high-energy grinding, mixing, and homogenization for hard, brittle, fibrous, and soft materials. Widely utilized across advanced ceramics, mineral processing, pharmaceuticals, chemical synthesis, battery development, and electronic materials, the system facilitates rapid particle size reduction down to colloidal fineness under wet, dry, or inert atmospheric conditions.

Semi-Circular Ergonomic Architecture and Observation Design The instrument features a semi-circular flip-open housing equipped with an integrated transparent observation window. This configuration allows laboratory operators to inspect the internal grinding station during setup and monitoring while providing ample clearance for loading and securing grinding jars. The chassis is engineered for benchtop operation, operating with an acoustic emission profile below 60 dB to maintain a quiet laboratory environment.

Precision Variable Frequency Drive and Programmable Dynamics Operating with a 0.75 kW motor, the mill is governed by a stepless Variable Frequency Drive (VFD) that ensures smooth acceleration and precise speed stabilization. The planetary geometry generates high centrifugal impact and shear forces, with revolution speeds adjustable from 35 to 335 rpm and planetary rotation speeds from 70 to 670 rpm. Intelligent programming allows users to configure total operating runs from 1 to 9999 minutes, alongside alternate forward and reverse cycle intervals from 1 to 999 minutes to eliminate sample agglomeration and cold-welding.

Flexible Jar Configurations and Controlled Atmosphere Milling The 2 L overall volumetric capacity supports four grinding positions, accommodating standard grinding jars ranging from 50 mL to 500 mL. For oxygen-sensitive, reactive, or pyrophoric materials, optional vacuum jars from 50 mL to 250 mL enable high-energy pulverization under inert gas blankets or vacuum environments. The platform accommodates a broad selection of jar and ball media—including agate, zirconium oxide, stainless steel, and tungsten carbide—to eliminate elemental cross-contamination.

Technical Specifications

Frequently Asked Questions (FAQ)

1. What is the total volume capacity and jar configuration of the 2A model?

The system has a 2 L total volumetric platform featuring four jar clamping positions that each accommodate standard grinding jars from 50 mL up to 500 mL.

2. Can this planetary ball mill grind under inert gas or vacuum conditions?

Yes, the machine supports optional specialized vacuum jars from 50 mL to 250 mL, allowing users to draw a vacuum or introduce inert protective gas for pyrophoric or easily oxidized powders.

3. What are the adjustable revolution and rotation speed ranges?

Controlled via a variable frequency drive, the revolution speed ranges from 35 to 335 rpm, while the counter-directional rotation speed ranges from 70 to 670 rpm.

4. How does the alternate forward and reverse rotation cycle function?

The digital controller allows setting alternate forward and reverse directional cycles from 1 to 999 minutes, preventing particulate sedimentation and material caking along the jar walls.

5. What is the maximum programmable run time for long milling tasks?

The operator can configure automated continuous or stepped milling runs from 1 up to 9999 minutes, enabling unattended operation for mechanical alloying tasks.

6. What is the noise emission level during standard laboratory grinding?

The enclosed semi-circular benchtop structure features balanced mechanical dynamics, maintaining operating noise at or below 60 dB.

7. Can operators view the grinding process while the machine is running?

The semi-circular flip-open upper cover incorporates a transparent observation window, facilitating safe visual monitoring of jar clamps and rotation mechanics.

8. Are grinding jars and media balls included with the base unit?

Grinding jars and milling balls are sold separately, allowing buyers to customize media materials (such as zirconia, agate, stainless steel, or tungsten carbide) to their analytical requirements.

9. Can this mill perform both dry and wet grinding operations?

Yes, the planetary drive mechanism is fully compatible with both dry pulverization and wet liquid-suspension milling to produce sub-micron and nano-scale colloidal slurries.

10. What power supply and bench requirements are necessary for installation?

The mill operates on standard single-phase 220 V, 50 Hz power with a 0.75 kW power draw, requiring a sturdy benchtop capable of supporting its 80 kg net weight.

11. Is it necessary to balance all four jar stations during every milling run?

Yes, to prevent centrifugal imbalance, excessive bearing wear, and mechanical vibration, jars of identical mass (including sample and balls) must be loaded symmetrically across opposing positions.

12. What sample materials are suitable for processing with this equipment?

The unit pulverizes hard, brittle, fibrous, and soft materials including geological ores, electronic ceramics, active battery materials, pigments, grains, and pharmaceutical active ingredients.
