Product catalog summary
Theoretical Foundations
The document explains the principles of centrifugation, focusing on the Relative Centrifugal Force (RCF), essential for particle separation. The RCF is calculated using the formula: F.C.R = 1.118 x 10-5 x r x n2, where 'r' is the radius and 'n' is the rotation speed in RPM.
Types of Rotors
  • Fixed Angle Rotor: Tubes are placed at a fixed angle, ideal for sedimenting dense particles like bacteria and cells.
  • Swing-out Rotor: Tubes swing to a horizontal position during rotation, suitable for density gradient separations.
Centrifugation Techniques
  • Differential Centrifugation: Used for sedimenting cells and large particles based on size and density.
  • Density Gradient Centrifugation: Allows separation of components based on density using a gradient medium.
Types of Centrifuges
  • Low-Speed Centrifuges: Suitable for basic laboratory applications.
  • High-Speed Centrifuges: Designed for microtubes and high-density samples.
  • Refrigerated Centrifuges: Maintain sample integrity by controlling temperature.
Models and Specifications
The catalogue lists various models with specifications such as capacity, speed, maximum RCF, and timer settings. For example, model 52615000 has a capacity of 6x15 mL, a speed of 4000 RPM, and a maximum RCF of 1790 g.
Accessories
Includes tubes, microtubes, and freezing boxes, enhancing the versatility and functionality of the centrifuges.
Key Features
  • Safety features like lid locks and alarms.
  • Versatile adapters for different tube sizes.
  • Maintenance-free induction motors in some models.
This document serves as a comprehensive guide for selecting the appropriate centrifuge based on specific laboratory needs, highlighting the importance of RCF and rotor type in achieving desired separation outcomes.
Overview
The document is a technical catalogue detailing various models of centrifuges, their specifications, and applications in laboratory settings. It covers small-sized centrifuges, high-speed centrifuges, and refrigerated centrifuges, highlighting their features, capacities, and operational parameters.
Small-Sized Centrifuges
These are portable and suitable for micro tubes with low sample values, offering FCR values from 2000 to 5000 G. They are used in molecular biology for PCR techniques, HPLC solution preparations, and microfiltration. Key features include angle rotors with adapters, silent operation with suction pads, transparent lids for rotor visibility, and a switching-mode power supply (100-240V).
High-Speed Centrifuges
Designed for centrifugation of cellular fractions with FCR values from 2000 to 20000 G. They feature fixed-angle rotors, digital control with LCD displays, speed adjustment in steps, adjustable timers, safety lid switches, and maintenance-free induction motors. These centrifuges are robust, silent, and vibration-free, suitable for laboratories with space constraints.
Refrigerated Centrifuges
These are high-speed desktop centrifuges with built-in refrigeration systems, used for protocols requiring low-temperature centrifugation, such as nucleic acid extraction and PCR sample preparation. Features include quiet operation, temperature, speed, and time displays, pre-cooling capabilities, CFC-free refrigerant use, and multiple safety mechanisms to prevent operation with an open lid.
Key Specifications
The document provides detailed specifications for each centrifuge model, including capacity, maximum speed, maximum FCR, and timer settings. It also lists accessories like rotors for specific models, highlighting their capacity and speed capabilities.
Applications
The centrifuges are applicable in various fields such as Biotechnology, Microbiology, Biochemistry, Biomedicine, and Molecular Biology, supporting tasks like blood sample processing, PCR preparation, and cellular fraction centrifugation.
Specifications
  • Microtubes and tubes are available in various capacities ranging from 0.2 mL to 50 mL, with different configurations for centrifuge use.
  • Rotors for centrifuge model 2818 are supplied separately.
  • Products are available in bags of 50 or 1000 units, depending on the capacity.
Procedures and Standards
  • All tubes can be sterilized in an autoclave and used at temperatures as low as -20 ºC.
  • Some tubes are graduated and have a conical bottom with a threaded cap for secure closure.
  • Non-graduated tubes have thicker walls to withstand centrifugal forces and are designed with a rim for optimal pouring.
Recommendations
  • Use polypropylene racks for organizing microtubes, available in various colors and dimensions, with alphanumeric labeling for sample identification.
  • Freezing boxes for centrifuge tubes are available with a numbered grid for sample identification.
Key Data from Tables
  • Racks are available for different tube capacities and alignments, with options for 24, 50, 72, and 100 tubes.
  • Dimensions and colors for racks and boxes are specified, ensuring compatibility with laboratory needs.

La centrífuga es el equipo que nos proporciona la técnica de separación basada en el movimiento de partículas por rotación y aceleración centrífuga de modo que, sometidas a altas velocidades durante cortos periodos de tiempo, permiten la sedimentación de los componentes de una solución homogénea según sus diferentes densidades. De esta manera, dicha solución queda finalmente separada en dos fracciones, la fracción sobrenadante y la fracción sedimentada que queda depositada en el fondo del tubo de centrifugación. Extensamente empleada en los campos de la Biología, la Bioquímica o la Medicina,...

El radio de giro es por lo tanto un factor determinante, junto con la velocidad de giro, en el cálculo de la FCR y es específica para cada rotor. El rotor o cabezal es el dispositivo que gira y en el que se colocan los tubos y pueden ser de dos tipos: Rotor angular: Los tubos se insertan en orificios en el interior de rotores macizos con un ángulo fijo. El caso extremo es el de los rotores verticales en los que el tubo se sitúa paralelo al eje de giro. Empleado habitualmente en la sedimentación de partículas de alta densidad como son bacterias, células o levaduras y en la separación isopícnica...
