Lab-Line 3D Rotator

Lab-Line Barnstead 3D Rotator Shaker – Fixed 30 RPM, 10-Degree Tilt, 6.75 x 5 Inch Platform, 120V (MPN: 4630)

The Lab-Line 4630 (manufactured under Barnstead / Lab-Line Instruments) is a rugged, compact benchtop 3D rotator shaker engineered to provide a smooth, three-dimensional gyroscopic mixing action for clinical, serological, and molecular biology procedures. Operating at a fixed speed of 30 RPM with a maximum 10-degree tilt angle from the horizontal plane, this heavy-duty platform mixer combines a circular motion with a gentle rocking waveform. This dual-action mechanics ensures thorough, low-foaming liquid agitation without introducing the high fluid shear forces that can damage delicate cellular suspensions, blood collections, or large macromolecular complexes. Featuring a compact 6.75 x 5 inch platform footprint, this steel-bodied unit provides continuous or timed operation inside restricted laboratory workspaces.

Technical Performance and Design

• Shear-Free 3D Gyroscopic Agitation: Integrates a fixed circular movement with an undulating rocking wave pattern. This combination provides uniform, low-foam agitation that keeps particulate suspensions, cells, and whole blood matrices evenly dispersed without sample shearing.

• Fixed 30 RPM Uniform Cadence: Programmed to maintain a constant operational speed of 30 RPM at a fixed 10-degree displacement tilt. This establishes a highly reproducible mixing environment across variable batch cycles and protocol loads.

• Dual-Mode Control Interface: Built with a manual control panel that supports both continuous processing and timed automation runs. The integrated mechanical timer can be dialed from 1 minute up to a maximum threshold of 60 minutes, turning off system power automatically at zero.

• Rugged All-Steel Body Housing: Fabricated with a heavy-gauge steel exterior frame and an enclosed drive motor assembly. This structural weight provides excellent benchtop anchoring, blocks dynamic creeping, and protects the gears from accidental fluid spills.

Key Benefits and Applications

• Serological and Immunoassay Mixing: The benchmark instrument selection for performing routine blood sample mixing, agglutination testing, latex diagnostics, and low-speed immunoassay processing loops.

• Gel Staining and Destaining: Provides a gentle, continuous wave motion that distributes wash buffers, staining solutions, and fixatives evenly across electrophoresis polyacrylamide gels without tearing the delicate polymer matrix.

• Space-Optimized Benchtop Footprint: The slim profile design easily fits inside congested biosafety hoods, environmental walk-in incubators, and small laboratory cold rooms operating down to plus 4 C.

• Anti-Slip Platform Baseline: Outfitted with a high-friction platform surface that securely holds test tube racks, small flasks, blot boxes, and multiwell culture plates in place during operational runs without needing physical clamps.
