Truelab D1008E ZeeMini Palm-Sized Centrifuge

Overview

The Truelab D1008E ZeeMini Palm-Sized Centrifuge is a compact, benchtop-ready centrifugal instrument engineered for rapid, reliable microsample separation in molecular biology, clinical diagnostics, and routine laboratory workflows. Operating on the principle of sedimentation under radial acceleration, it delivers precise and repeatable centrifugal force to separate suspended particles—such as cellular debris, precipitated proteins, or nucleic acid complexes—from liquid phases within microvolume containers. Designed specifically for low-volume applications (0.2–2.0 mL), this device integrates fixed-angle rotor geometry optimized for high efficiency in small-tube formats including standard microcentrifuge tubes, PCR strips, and filter-based spin columns. Its brushless DC motor ensures stable rotational performance across variable line voltages (100–240 V, 50/60 Hz), eliminating speed drift due to power fluctuations—a critical feature for labs with unstable grid conditions or mobile deployment scenarios.

Key Features

• Compact footprint (150 × 150 × 117 mm) and ultra-lightweight design (0.5 kg) enable placement on crowded benches, biosafety cabinets, or transport between workstations without compromising stability.
• Dual interlock lid mechanism prevents operation unless fully closed, meeting IEC 61010-1 safety requirements for laboratory electrical equipment; automatic rotor stop upon lid opening ensures operator protection.
• Patented quick-release rotor system allows tool-free removal and reinstallation of the fixed-angle rotor—reducing cleaning downtime and minimizing cross-contamination risk during high-throughput sample processing.
• Ultra-quiet operation at ≤45 dB(A) enables use in noise-sensitive environments such as teaching labs, point-of-care settings, or shared core facilities without acoustic interference.
• Intuitive flip-lid activation: centrifugation initiates immediately upon closure and halts instantly when opened—eliminating manual start/stop button presses and reducing procedural steps.
• Multi-format compatibility supported via interchangeable adapters: accommodates 0.2 mL, 0.5 mL, 1.5 mL, and 2.0 mL microtubes; 16-position 0.2 mL PCR tube racks; and dual 8-well PCR strip carriers.

Sample Compatibility & Compliance

The D1008E ZeeMini supports standard polypropylene and polyethylene microcentrifuge tubes, including spin-filter columns used in DNA/RNA purification kits and protein desalting workflows. Its rotor geometry maintains consistent wall shear profiles across all compatible tube sizes, ensuring reproducible pelleting efficiency. The unit complies with international safety and electromagnetic compatibility standards, including TÜV Rheinland certification per EN 61010-1 (2013) and EN 61326-1 (2013), verifying conformity with EU Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU). While not classified as a GLP/GMP-regulated instrument per se, its consistent RCF output (2680 × g at 5000 rpm), traceable speed calibration, and non-volatile runtime memory support audit-ready documentation in regulated QC/QA environments.

Software & Data Management

As a standalone analog-controlled centrifuge, the D1008E ZeeMini does not incorporate embedded firmware, touchscreen interface, or digital connectivity. All operational parameters—including speed (rpm), run time (continuous mode only), and RCF—are set manually via mechanical controls. This architecture eliminates software validation requirements and reduces long-term maintenance complexity. For laboratories requiring electronic recordkeeping, optional external timing devices or lab information management systems (LIMS) may be integrated via manual log entry. No data export, remote control, or FDA 21 CFR Part 11-compliant audit trail functionality is provided—consistent with its role as a dedicated, entry-level separation tool.

Applications

• Routine pelleting of PCR products, restriction digests, and enzymatic reaction mixtures prior to electrophoresis or downstream analysis.
• Clarification of bacterial lysates, tissue homogenates, and cell culture supernatants in preparative molecular workflows.
• Spin-down of filtration columns during nucleic acid extraction, buffer exchange, or desalting procedures.
• Centrifugal concentration of dilute protein samples using ultrafiltration devices rated for ≤2680 × g.
• Point-of-care sample preparation in field-deployable diagnostic platforms where size, weight, and power resilience are critical constraints.

FAQ

What is the maximum relative centrifugal force (RCF) achievable with the D1008E model?

The D1008E achieves a maximum RCF of 2680 × g at its rated speed of 5000 rpm.
