Edmund Büehler KS15A Smart Compact Orbital Shaker

Overview

The Edmund Büehler KS15A Smart Compact Orbital Shaker is a precision-engineered laboratory shaker designed for consistent, low-vibration orbital motion in life science and biotechnology applications. Based on the proven principle of eccentric drive orbital agitation—where a motor-driven cam generates a uniform 15 mm circular orbit—the KS15A delivers highly reproducible mixing, suspension, and aeration performance across microplates, test tubes, Erlenmeyer flasks (up to 250 mL), and small-volume culture vessels. Its compact footprint (220 × 220 mm) and lightweight aluminum-magnesium alloy housing make it ideal for benchtop use in biosafety cabinets, cold rooms, and shared core facilities where space and thermal management are constrained. Engineered in Germany to DIN-certified manufacturing standards, the unit integrates a brushless DC motor for maintenance-free operation, extended service life, and minimal electromagnetic interference—critical in environments co-located with sensitive analytical instrumentation.

Key Features

• Intuitive touch-sensitive LED interface with rotary encoder for precise parameter adjustment and real-time feedback
• Programmable speed control (30–300 rpm) with ±1 rpm accuracy and ramp-up/ramp-down profiles to prevent splashing or cell shear
• Stable 15 mm orbit diameter optimized for homogeneous suspension of mammalian cells, bacterial cultures, and immunoassay plates
• Robust platform with non-slip silicone mat and universal clamping options (including optional microplate holders and tube racks)
• Low-noise operation (<45 dB(A) at 200 rpm) and thermally passive design enabling continuous operation at ambient temperatures from 5 °C to 40 °C
• Integrated safety features: automatic shutdown on overload detection, tilt compensation, and motor overtemperature protection

Sample Compatibility & Compliance

The KS15A accommodates standard ANSI/SLAS-format microplates (96-well, 384-well), conical tubes (15–50 mL), glass vials (10–30 mL), and small Erlenmeyer flasks (up to 250 mL) when used with compatible accessories. Its mechanical design conforms to ISO 8573-1 (compressed air purity classes) for compatibility with cleanroom-adjacent workflows and meets IEC 61000-6-2 (immunity) and IEC 61000-6-3 (emission) for electromagnetic compatibility in regulated laboratory environments. The device carries CE marking under the EU Machinery Directive 2006/42/EC and RoHS 2011/65/EU compliance for hazardous substance restriction. While not inherently GLP/GMP-certified, its stable performance, traceable speed calibration, and audit-ready operational logs (via optional USB data export) support alignment with internal SOPs for QC microbiology, assay development, and upstream bioprocess screening.

Software & Data Management

The KS15A operates as a standalone instrument with embedded firmware supporting up to 10 user-defined protocols stored in non-volatile memory. Speed, runtime, and ramp profiles are retained after power cycling. Optional USB-C connectivity enables firmware updates and time-stamped operational log export (CSV format), including start/stop timestamps, average speed deviation, and fault codes—facilitating retrospective review during internal audits or method validation. While no proprietary PC software is required, exported logs integrate natively with LIMS platforms compliant with ASTM E1578-22 (Laboratory Information Management Systems) and support 21 CFR Part 11-compliant electronic record retention when paired with validated third-party data archiving solutions.

Applications

• Cell culture maintenance: gentle resuspension of adherent and suspension lines prior to passaging or harvesting
• ELISA and lateral flow assay preparation: uniform coating and washing steps requiring consistent orbital agitation
• Molecular biology workflows: plasmid miniprep binding/wash cycles, PCR master mix homogenization, and enzymatic reaction incubation
• Microbiology: aerobic bacterial growth enhancement in liquid media, antibiotic susceptibility testing plate agitation
• Protein biochemistry: solubilization of inclusion bodies, ligand-binding equilibrium studies in microcentrifuge tubes
• Educational labs: standardized demonstration of kinetic mixing parameters in undergraduate biotechnology curricula

FAQ

Is the KS15A suitable for use inside a CO₂ incubator?
No—the KS15A is rated for ambient operation only (5–40 °C, non-condensing) and lacks ingress protection beyond IP21; it is not certified for humidified or elevated-CO₂ environments.
Can I calibrate the speed independently?
Yes—speed calibration is accessible via service mode using the rotary encoder; users may verify against a calibrated tachometer per ISO/IEC 17025-recommended practices.
Does the shaker support timed run termination?
Yes—runtime can be set from 1 minute to 99 hours 59 minutes, with audible and visual alerts upon completion.
What accessories are available for high-throughput formats?
Edmund Büehler offers certified 96-well microplate clamps, universal tube carriers (for 1.5/2.0 mL and 15/50 mL), and autoclavable silicone platform inserts—all mechanically tested for resonance suppression at maximum speed.
Is remote monitoring or Ethernet connectivity supported?
Not natively; the KS15A is a local-control instrument. Integration into building management systems requires external IoT gateways and custom middleware configuration.
