HERMLE
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.
