Screw feeder: LabDos Solid-SCR

Suitable for vacuum and overpressure

Precise screw feeding for small amounts under challenging conditions

The screw feeder LabDos-SCR is the optimal solution for continuously dosing small quantities of powders and crystals. The small outlet opening prevents rising vapors from entering the conveying mechanism, ensuring trouble-free operation, even with challenging materials.

Thanks to its slim design, the screw feeder can be mounted directly on NS29/32 and operates in the range of 0.01-200 rpm. This ensures safe integration into Laboratory Reactor Systems for laboratories and pilot plants.

Features & benefits:

• Continuous, uniform dosing: No shock operation – the rotating screw conveyor guarantees a continuous material supply and stable process conditions.
• Broad adjustment range for precise dosing rates: The finely adjustable speed enables precise dosing - from the slowest feeds to higher delivery rates.
• Optional reactor integration: Dosing into reactors with pressures up to 5 bar and process temperatures up to 500 °C – for flexible operation even under challenging process conditions.
• Robust and chemically resistant: All parts that come into contact with the medium are made of high-quality stainless steel in the standard version – optionally with nitrogen purge connections for inertization and drying.
• Flexible control – stand-alone or integrated: Operation via a dedicated control unit with analog or serial interface – or fully embedded into your automation system, e.g. via LabManager or LabBox.

Typical applications:

• Feindosierung kristalliner oder pulverförmiger Edukte
• Continuous addition of material under vacuum or pressure conditions
• Integration in Laborreaktorsysteme mit hohen Anforderungen an Genauigkeit und Hygiene

For particularly shear-sensitive or fragile solids, we recommend our drum feeder LabDos Solid-DRM with very gentle conveying characteristics and gravimetric control.
