Product news

Thermo Electron Corporation, the world leader in analytical instruments, today introduced the latest versions of its highly successful Heraeus® Pico™ & Fresco™ microcentrifuges.

Designed to cover a broad spectrum of life science research areas, these new models accelerate researchers’ routine sample preparation processes by delivering higher speeds, improved safety and convenience, an enhanced user interface and an expanded rotor set. These and other enhancements are available on four new models: the ventilated Heraeus Pico, available in a 17,000 x g version and a brand new 21,000 x g version, and the refrigerated Heraeus Fresco, also available in both 17,000 x g and 21,000 x g models.

The new Heraeus Pico & Fresco microcentrifuges offer researchers outstanding flexibility and throughput by providing the widest range of high-capacity rotors available for their size, supporting sample formats ranging from hematocrit tubes to open mini-preps. The unique “click-close” bio-containment lid system ensures user safety and confidence. Combined with the large, easy-to-read digital display, the Heraeus Pico & Fresco microcentrifuges are the perfect high-speed solution for micro-volume protocols such as nucleic acid preparation, protein isolation and reaction set-up.

For increased throughput the Heraeus Pico & Fresco microcentrifuges provide rapid acceleration and deceleration rates on all models. The broad rotor set includes a new 18-place dual-row rotor that accepts 2.0 ml and 0.5 ml tubes which eliminates the need for rotor changes. The highly corrosion-resistant rotor materials can be autoclaved and cleaned repeatedly with the harshest detergents.

Delicate samples can be spun on all models and for precise temperature control, the Heraeus Fresco 17 and Heraeus Fresco 21 feature efficient refrigeration systems that maintain temperatures between -9°C and +40°C in 1°C increments.

Thermo’s Heraeus Microcentrifuge Series is designed to address the needs of both small and large labs carrying out extensive micro-volume protocols. With more than 100 years of combined R&D experience Thermo has produced exceptional performance, throughput and flexibility for all pharmaceutical, biotechnology and academic research laboratories.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.CentrifugesCentrifuges are used to separate particulates suspended in a liquid via the application of a centrifugal force including cells, macromolecules, nanoparticles and precipitates. Centrifuges come in three sizes: microcentrifuges, benchtop and floor-standing centrifuges, depending on the volume and number of samples that require separation. When choosing a centrifuge, consider its maximum separation power indicated by its relative centrifugal force (RCF) value. Low force centrifuges reach a maximum RCF of 8,000 g, high-force centrifuges can reach maximum RCF values of 80,000 g. For extremely high forces, consider ultracentrifuges (up to 800,000 g). Refrigerated and vacuum centrifuges also known as concentrators are available for more specialized applications. A range of volumes are available for centrifuge tubes and microfuge tubes, depending on sample sizes.

Consequently, the importance of high-quality DNA/RNA extraction and purification equipment cannot be underestimated. Many purification kits are available and are typically optimized for nucleic acid type and source, including plasmid DNA, genomic DNA, mRNA, RNA and viral nucleic acid purification kits. Automated extraction and purification of nucleic acids can be implemented with magnetic bead separator instruments or high-throughput purification workstations.

The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.
