Overview
The IKA Trayster Basic is a top-loading inversion mixer engineered for precise, gentle, and reproducible homogenization of biological samples in standard laboratory tubes. Unlike orbital or reciprocating shakers, the Trayster Basic operates on a fixed-axis rotational inversion principle—rotating sample carriers 180° around a horizontal axis at a constant speed of 20 rpm. This motion induces controlled tumbling without shear stress, making it especially suitable for delicate applications such as reconstitution of lyophilized proteins, mixing of blood derivatives (e.g., platelet-rich plasma), and suspension of particulates in viscous media. Its robust aluminum housing and brushless DC motor ensure long-term reliability under continuous operation conditions, while its compact footprint and low power draw support integration into biosafety cabinets, cold rooms, and multi-instrument benchtop configurations.
Key Features
- Fixed-speed inversion mechanism optimized for low-shear mixing at 20 rpm—ideal for sensitive biomolecules and cell suspensions
- Top-loading design enables rapid access to samples without disturbing adjacent equipment or requiring vertical clearance
- Interchangeable fixtures compatible with common tube formats including Eppendorf® 1.5–2.0 mL microcentrifuge tubes and Greiner Bio-One® 15–50 mL conical tubes
- Tool-free, snap-fit fixture mounting system allows quick disassembly and thorough cleaning after accidental spillage or cross-contamination events
- IP21-rated enclosure provides protection against vertically falling drips and solid objects >12.5 mm, supporting safe use in general laboratory environments
- Wide ambient operating range (4–50 °C) permits deployment in refrigerated workspaces, incubators, or temperature-controlled cleanrooms
- Touch-sensitive control panel with intuitive single-button interface—no firmware updates, no software dependencies
Sample Compatibility & Compliance
The Trayster Basic accommodates tubes up to 50 mL in volume when mounted on appropriate fixtures (sold separately). It maintains mechanical stability under full load (≤2 kg including fixture and samples), ensuring consistent motion profile across batch sizes. While not certified for GLP/GMP-regulated workflows out-of-the-box, its fixed-speed architecture and absence of programmable logic eliminate variability associated with timer drift or parameter misconfiguration—supporting traceability in quality-controlled environments. The device complies with DIN EN 60529 (IP21), IEC 61010-1 (safety requirements for electrical equipment), and EMC Directive 2014/30/EU. For laboratories subject to FDA 21 CFR Part 11, manual log entries documenting usage time, operator ID, and sample identifiers are recommended to meet audit trail expectations.
Software & Data Management
The Trayster Basic operates as a standalone hardware unit with no embedded microprocessor, network interface, or data logging capability. It does not feature USB, RS232, or analog output ports; therefore, no proprietary software, drivers, or cloud connectivity is required—or supported. This architecture eliminates cybersecurity risks, firmware validation overhead, and compatibility concerns across operating systems. All operational parameters are immutable by design: speed is factory-set at 20 rpm, and runtime is manually controlled by the user. For labs implementing electronic lab notebooks (ELNs) or LIMS, integration occurs via manual entry or barcode-scanned protocol association—not real-time telemetry.
Applications
- Rehydration of freeze-dried reagents and diagnostic kits
- Homogenization of whole blood, serum, and plasma prior to centrifugation or analysis
- Blending of antibody conjugates and nanoparticle suspensions
- Preparation of calibration standards and QC reference materials in clinical chemistry
- Mixing of agarose or acrylamide solutions before gel casting
- Equilibration of membrane protein samples in detergent buffers
FAQ
Is the Trayster Basic suitable for use inside a cold room or refrigerator?
Yes—the device is rated for continuous operation between 4 °C and 50 °C, and its sealed electronics prevent condensation-related failure in high-humidity chilled environments.
Does the unit include tube holders or clamps?
No—only the base unit is supplied. Fixtures for specific tube types (e.g., 24-position microtube carrier, 8-position 50 mL rack) must be ordered separately using IKA’s accessory catalog numbers.
Can the rotation speed be adjusted?
No—speed is permanently fixed at 20 rpm to ensure mechanical consistency and eliminate calibration drift over time.
What maintenance is required?
Routine cleaning of the platform and fixtures with 70% ethanol or isopropanol is recommended after each use. No lubrication, belt replacement, or sensor recalibration is necessary during the product lifecycle.
Is the Trayster Basic compliant with ISO 13485 or GMP Annex 11?
It is not formally certified to these standards, but its deterministic behavior, lack of configurable parameters, and minimal electronic subsystems simplify qualification protocols (IQ/OQ/PQ) in regulated settings.
