HERMLE

HERMLE Labortechnik GmbH is a German manufacturer of laboratory centrifuges and related accessories, based in Wehingen, Baden-Württemberg. The company has been producing centrifugation equipment since the mid-20th century, and its product line spans benchtop and floor-standing centrifuges, fixed-angle and swing-out rotors, and a range of adapters and inserts that allow a single rotor to accommodate different tube and bottle formats. HERMLE centrifuges are used in clinical, research, industrial, and quality-control laboratories for applications such as sample preparation, cell separation, and sedimentation. The product families include universal benchtop centrifuges (e.g., Z207, Z307, Z327 series), refrigerated models (e.g., Z327-K), micro-centrifuges, and a comprehensive selection of rotors and accessories. Key technical characteristics across the line include programmable operation, variable speed control, digital displays, and compatibility with standard tube sizes (15 mL, 50 mL, 200 mL, 500 mL). Many models operate on 120V AC, making them suitable for North American and other markets using that voltage. Build standards typically feature robust construction with metal housings and lids, and safety features such as lid locks and imbalance detection. 3G Electric supplies HERMLE centrifuges and accessories globally, with a catalog of 89 SKUs covering complete units, rotors, adapters, and inserts. This includes conical inserts for 15 mL tubes (e.g., Z446-750-B15), tube adapters for 30 mL tubes (e.g., Z326-50-A30), and flat bottle inserts for 500 mL bottles (e.g., Z496-1L-A500S). The availability of these components allows laboratories to configure a centrifuge for specific tube types and volumes without replacing the entire rotor. 3G Electric supports the HERMLE line by providing access to both instruments and the consumable accessories required for ongoing operation, with the ability to source specific part numbers and provide technical specifications for procurement and engineering teams. For plant engineers and maintenance managers, HERMLE centrifuges offer a combination of programmable protocols, reproducible results, and a modular accessory system that can be adapted to changing sample formats. The benchtop models are designed for space-constrained environments, while refrigerated units (e.g., Z327-K) allow temperature-sensitive samples to be processed without external cooling. The rotor and adapter system is central to the brand's flexibility: a single rotor can accept different inserts to hold various tube sizes, reducing the need for multiple rotors. This is particularly relevant in multi-user laboratories where sample types vary. 3G Electric's role is to make these components available as individual SKUs, so procurement specialists can order exactly the part required, whether it is a complete centrifuge or a specific adapter. The catalog includes both current and legacy part numbers, supporting maintenance and replacement needs. All products are supplied with manufacturer part numbers for traceability. 3G Electric does not manufacture HERMLE products; it distributes them. Technical documentation, including specifications and compatibility information, is available for each SKU to assist with selection and integration into existing laboratory workflows.

Frequently asked questions

Common questions about HERMLE from 3G Electric.

What is the difference between the HERMLE Z327 and Z327-K centrifuges?

The HERMLE Z327 is a non-refrigerated universal benchtop centrifuge with a 4 x 200 mL capacity, programmable operation, variable speed control, and a digital display. The Z327-K is the refrigerated version of the same model, allowing temperature-sensitive samples to be processed at controlled temperatures. Both operate on 120V AC and are designed for use with centrifuge tubes. The choice between them depends on whether sample integrity requires cooling during centrifugation. The Z327-K includes refrigeration components, which may affect the unit's footprint and power consumption compared to the non-refrigerated Z327.

What HERMLE rotor adapters are available for 15 mL conical tubes?

HERMLE offers the Conical Insert with MPN Z446-750-B15, which is a rotor riser designed to hold 15 mL conical tubes securely during centrifugation. This adapter is compatible with specific HERMLE rotors and enables precise tube positioning. It is used when a rotor's standard bore does not directly accept 15 mL conical tubes. The insert is a separate SKU, allowing laboratories to adapt existing rotors to different tube formats without purchasing a new rotor. For compatibility with a specific rotor model, consult the rotor's technical documentation or contact 3G Electric with the rotor part number.

Can the HERMLE Z207-A centrifuge accommodate both 15 mL and 50 mL tubes?

The HERMLE Z207-A is a universal benchtop centrifuge with a capacity of 8 x 15 mL tubes. A variant, the Z207-A-CMB, accommodates 4 x 15/50 mL tubes, meaning it can hold either 15 mL or 50 mL tubes depending on the rotor or adapter configuration. The Z207-A itself is limited to 15 mL tubes unless used with a compatible rotor that accepts adapters for other sizes. Both models feature digital displays, variable speed control, and programmable operation, and operate on 120V AC. For specific tube compatibility, refer to the rotor and adapter specifications.

What is the purpose of the HERMLE flat bottle insert Z496-1L-A500S?

The HERMLE Flat Bottle Insert (MPN Z496-1L-A500S) is a rotor adapter designed to hold 500 mL flat bottles during centrifugation. It is used with compatible HERMLE rotors to enable the processing of larger volumes in bottles rather than tubes. This insert is typically used in applications such as sample preparation, sedimentation, and separation where larger volumes are required. It ensures secure positioning of the bottle within the rotor, maintaining balance and safety during operation. The insert is a separate component, allowing a rotor to be adapted for bottle processing without replacing the entire rotor.

Are HERMLE centrifuges compatible with standard laboratory tubes?

HERMLE centrifuges are designed to work with a range of standard laboratory tube sizes, including 15 mL, 50 mL, and 200 mL, depending on the model and rotor configuration. The use of adapters and inserts, such as the Conical Insert for 15 mL tubes or the Tube Adapter for 30 mL tubes, allows compatibility with various tube types and brands. The rotor system determines the maximum tube size and number. For example, the Z327 series accepts 4 x 200 mL, while the Z207-A accepts 8 x 15 mL. It is important to match the tube dimensions to the rotor or adapter specifications to ensure proper fit and safe operation.

What voltage do HERMLE benchtop centrifuges require?

The HERMLE benchtop centrifuges listed, including the Z207-A, Z207-A-CMB, Z307, Z327, and Z327-K, operate on 120V AC. This voltage is standard in North America and some other regions. For use in countries with different mains voltages, a suitable transformer or alternative voltage model may be required. It is important to verify the voltage requirement of the specific model before ordering, as HERMLE may offer variants for different markets. The product specifications provided by 3G Electric indicate the voltage for each SKU.
