Schuett-biotec Homgen plus Benchtop Grinding Homogenizer

Overview

The Schuett-biotec Homgen plus is a precision-engineered benchtop grinding homogenizer designed for gentle yet effective mechanical disruption of biological and soft-tissue samples under controlled thermal conditions. Unlike high-shear rotor-stator or ultrasonic systems, the Homgen plus operates on the principle of controlled rotational grinding—where a motor-driven pestle rotates within a precisely fitted homogenization tube, generating consistent shear and compressive forces to lyse cells, disperse aggregates, and homogenize viscous or fibrous matrices. This method ensures high reproducibility, minimal foaming, and negligible nucleic acid shearing—making it especially suitable for downstream applications requiring intact RNA, native proteins, or functional organelles. Its low-noise, high-torque motor enables stable operation at speeds as low as 40 rpm for delicate samples and up to 3000 rpm for tougher tissues—without compromising sample integrity or operator safety.

Key Features

• Modular, height-adjustable design: Motor head and chuck assembly can be vertically repositioned to accommodate tubes from 1.5 mL Eppendorf microcentrifuge tubes up to 40 mL conical vessels.
• Integrated cryo-shield: Transparent polycarbonate cooling jacket accepts ice packs or chilled coolant to maintain sub-ambient temperatures during prolonged homogenization—critical for protease- or nuclease-sensitive samples.
• Multi-material pestle compatibility: PTFE pestles for soft tissues (e.g., liver, brain); borosilicate glass pestles for fibrous or calcified samples (e.g., muscle, bone); and reinforced glass-fiber–embedded PTFE pestles for exceptionally resilient materials (e.g., plant seeds, fungal mycelia).
• LED digital display with real-time speed readout and infinitely variable speed control (40–3000 rpm), enabling precise protocol replication across users and shifts.
• Three-point stabilized base frame and rigid aluminum support column ensure vibration-free operation—even at maximum torque—reducing mechanical stress on both instrument and sample tubes.
• CE-certified electrical architecture with thermal overload protection and automatic motor shutdown upon abnormal load detection.

Sample Compatibility & Compliance

The Homgen plus supports a broad spectrum of biological and environmental sample types—including mammalian and plant tissues, cultured cells, bacterial pellets, soil suspensions, and environmental biofilms—across volumes from 1.5 mL to 40 mL. All standard homogenization tubes (conical or round-bottom) are manufactured from autoclavable, chemically resistant polypropylene or borosilicate glass, compatible with common lysis buffers (RIPA, TRIzol®, QIAzol®, and SDS-based formulations). The system meets CE marking requirements for laboratory equipment (2014/30/EU EMC Directive and 2014/35/EU Low Voltage Directive) and is routinely deployed in ISO 17025-accredited labs and GLP-regulated environments. While not inherently 21 CFR Part 11 compliant, its digital speed logging (via optional external data logger integration) supports audit-ready documentation when used within validated SOPs.

Software & Data Management

The Homgen plus is a standalone hardware platform with no embedded firmware or proprietary software interface. Speed settings and runtime are manually configured via front-panel controls; all operational parameters are retained in user-maintained lab notebooks or electronic lab notebooks (ELNs). For traceability-critical workflows, third-party data acquisition systems (e.g., LabVIEW, Python-based serial loggers) may interface via the device’s RS-232 port (optional adapter required) to record timestamped speed profiles. No cloud connectivity, remote access, or built-in audit trail is provided—consistent with the design philosophy of robust, maintenance-light instrumentation intended for regulated routine use.

Applications

• Preparation of high-yield, low-degradation RNA extracts from neural tissue and embryonic samples.
• Isolation of intact mitochondria and synaptosomes from rodent brain homogenates.
• Homogenization of fibrous plant material (e.g., Arabidopsis leaves, maize kernels) prior to metabolite extraction.
• Dispersion of biofilm fragments from medical device surfaces for viable CFU enumeration.
• Cell lysis optimization studies requiring precise kinetic control over mechanical energy input.
• Standardized sample prep for LC-MS/MS proteomics workflows where protein denaturation must be minimized prior to digestion.

FAQ

What sample volumes can the Homgen plus process?
It accommodates volumes from 1.5 mL (in standard 2 mL Eppendorf tubes) up to 40 mL (in supplied conical or round-bottom homogenization tubes).
Is the instrument suitable for hard or mineralized tissues?
Yes—when paired with borosilicate glass or glass-fiber–reinforced PTFE pestles, it effectively processes cartilage, bone chips, and dried plant matter without pestle fracture.
Can the Homgen plus be integrated into automated liquid handling workflows?
No—it is a manually operated, stand-alone unit without robotic arm interfaces, barcode readers, or API-level control protocols.
Does the cryo-shield require active cooling?
No—thermal management is passive: users insert pre-chilled ice packs or cold gel packs into the polycarbonate jacket; no refrigeration unit or circulating coolant is needed.
Are replacement pestles and tubes supplied with lot-specific certificates of conformance?
Yes—certificates of conformance (CoC) are available upon request for all consumables bearing Schuett-biotec part numbers, including traceable batch data for glass and PTFE components.
