AIRFUGE AIR-DRIVEN ULTRACENTRIFUGE

Product catalog summary

Overview: The document outlines the specifications and applications of various rotors used in the Airfuge air-driven ultracentrifuge, designed for tasks such as clarifying lipemic samples, pelleting subcellular components, and preparing samples for electron microscopy.

Specifications: The document details several rotors, each with unique characteristics like maximum speed, relative centrifugal field, pressure at maximum speed, rotor capacity, and K-factor. For instance, the ACR-90 Chylomicron Rotor operates at 90,000 RPM, generating up to 122,000 x g with a 3.5 mL liner.

Applications: Each rotor serves specific purposes. The ACR-90 is used for clarifying lipemic serum by floating chylomicrons. The A-95 and A-110 rotors are suitable for pelleting subcellular components and isolating microsomal fractions. The Batch Rotor processes larger sample volumes like fruit paste, while the EM-90 Electron Microscopy Rotor sediments particles onto supports for electron microscopy.

Operational Details: The Airfuge uses air pressure, requiring 42 psi from a lab air source, achieving high speeds quickly to reduce run times. It allows smooth deceleration, minimizing remixing of tube contents, with runs timed from 0 to 300 minutes and a HOLD option for longer durations.

Key Features: The Airfuge is designed for rapid processing with minimal preparation time, achieving high g-forces with short path lengths, making it efficient for small volume samples. The rotors operate nearly friction-free on a cushion of levitating air.

Additional Specifications:

Air Pressure: 30 psi (210 kPa) for routine operation.
Acceleration Time: 30-60 seconds.
Deceleration Time: 2.5-5.5 minutes.
Speed Control: Regulated by air pressure.
Speed Readout: Conversion from air pressure reading; optional digital readout available.
Braking System: Coasting followed by frictional braking.
Temperature Range: Rotor temperature slightly above ambient.
Timer: 0-300 minutes in five-minute increments, with a HOLD option for longer runs.
Dimensions: 280 x 380 x 200 mm (11 x 15 x 8 in).
Weight: 10.4 kg (23 lbs).

Product Variants:

340400: 120 V, 60 Hz.
347854: 120 V, 60 Hz with Digital Tachometer.
340401: 220 V, 50 Hz.
347855: 220 V, 50 Hz with Digital Tachometer.

Features:

Compact, turbine-driven, benchtop ultracentrifuge.
Capable of accelerating rotors up to 110,000 RPM in 30 seconds.
No vacuum or high-speed bearings required; rotor supported by air streams.

Requirements:

Air Source: 3.5 cubic feet per minute (0.0016 m3/s) at 42 psi (290 kPa).
Power: 120 V, 60 Hz or 220 V, 50 Hz.

Accessories:

Includes connecting hose and air filter; rotors and accessories ordered separately.

ULTRACENTRIFUGE POWER FOR SMALL VOLUME SAMPLES Dedicated applications include: • inding studies right on your workbench B • Lipoproteins • larification of lipemic samples C • Proteomics • ample preparation for electron microscopy S • Soluble solid/total solids ratios for tomato canning applications How it works: The Airfuge is air turbine-driven and delivers results in a fraction of the time of larger units. The combination of high g-force and short path length results in remarkably short run times to produce results. Run time is shortened even further by rotor acceleration to full speed—110,000...
