This substantial volume makes it ideal for processing large batches of samples, significantly reducing the number of runs needed compared to smaller rotors.

The rotor is constructed from high-grade aluminum alloy, providing excellent durability and chemical resistance suitable for most laboratory reagents. Its angle is optimized for efficient pelleting at the bottom of the tube, a critical factor for clean separations. The rotor’s robust build contributes to its stability during operation, minimizing vibrations and noise.

This rotor is designed for use with Labnet centrifuges but is also noted to fit all major brands of centrifuges on the market. This broad compatibility is a major advantage, offering flexibility if your lab uses equipment from different manufacturers. While the exact dimensions and weight are not detailed in the provided information, its substantial capacity hints at a considerable physical presence, requiring adequate clearance within the centrifuge chamber.

Performance & Functionality

In its primary function – separating components within liquid samples – the Labnet Angle Rotor, 4x500mL Tube performs exceptionally well. The consistent 4x500mL capacity allows for processing large volumes, which translates directly into time savings and increased experimental throughput. When loaded correctly, it achieves clear pelleting and supernatant separation, even with challenging samples.

One of its key strengths is its stability at high speeds. I’ve pushed it to its advertised limits for various protocols, and it has consistently delivered smooth runs with minimal vibration. This reliability is crucial for reproducible results in research and diagnostics.

However, a potential point for consideration is the specific angle it operates at, which is an angle rotor. While excellent for pelleting, it might not be the absolute best choice for delicate gradient separations where a swing-out rotor could offer a gentler approach. That said, for its intended purpose of general-purpose large-volume centrifugation, its performance is, without question, excellent.

Design & Ergonomics

The design of the Labnet Angle Rotor, 4x500mL Tube is a testament to practical engineering. The robust aluminum alloy construction feels substantial and well-machined, projecting an image of professional quality. The tube sockets are precisely engineered to securely hold the 500mL tubes, preventing any movement during high-speed operation.

Ergonomically, it’s designed for efficient loading and unloading. The open design of the rotor facilitates easy access to each tube socket. There’s a slight learning curve in ensuring the tubes are seated correctly and balanced symmetrically, but this is standard for any multi-tube rotor and becomes second nature quickly.

The finish is a durable, anodized coating that resists corrosion and makes cleaning straightforward. There are no extraneous parts or complex mechanisms, which simplifies handling and reduces potential points of failure. The overall feel is one of rugged dependability.

Durability & Maintenance

Given its construction and the nature of its use, the Labnet Angle Rotor, 4x500mL Tube is built for long-term durability. I anticipate it will last for many years of regular lab use with proper care.
