Langbo KBC-82A Programmable Orbital Shaker

Overview

The Langbo KBC-82A Programmable Orbital Shaker is an engineered platform for precise, reproducible agitation of biological and chemical samples under controlled thermal conditions. Utilizing orbital motion with a fixed 30 mm diameter trajectory, it generates uniform mixing without vortexing—ideal for cell culture suspension, microbial growth, enzyme assays, solubility studies, and reagent homogenization. Unlike reciprocating or rocking shakers, orbital agitation minimizes shear stress on sensitive eukaryotic cells while ensuring consistent oxygen transfer and nutrient distribution across flasks, tubes, and multiwell plates. Its integrated Peltier-based heating system enables stable temperature maintenance from ambient up to 60 °C, supporting applications ranging from mesophilic bacterial incubation to protein expression protocols requiring elevated but non-sterilizing temperatures.

Key Features

• Programmable dual-parameter control: independent setting of speed (30–300 rpm) and temperature (ambient to 60 °C) with real-time digital display
• High-resolution timer with 1-minute resolution and extended range (1–999 hours), supporting unattended overnight and multi-day experiments
• Robust aluminum alloy platform with non-slip silicone mat; accommodates standard Erlenmeyer flasks (50–2000 mL), test tubes, Petri dishes, and microtiter plates
• Brushless DC motor ensures low-noise operation (<55 dB(A)), long service life, and consistent torque delivery across the full speed range
• Over-temperature and over-speed safety cutoffs compliant with IEC 61010-1 for laboratory equipment safety
• Front-panel membrane keypad with intuitive navigation; no software installation required for basic operation

Sample Compatibility & Compliance

The KBC-82A supports a broad range of sample containers and volumes without modification. Its single-platform design maintains mechanical stability even at maximum speed and load (up to 15 kg distributed evenly). The unit meets general-purpose laboratory safety standards per IEC 61010-1 and conforms to electromagnetic compatibility requirements (EN 61326-1). While not certified for ISO 5 cleanroom use or GMP-grade validation out-of-the-box, its construction—stainless steel interior chamber walls, sealed electronics, and absence of lubricants in the drive train—facilitates routine cleaning and supports GLP-aligned documentation practices. Users performing regulated work may implement additional operational qualification (OQ) protocols aligned with ASTM E2500 or ISO/IEC 17025 guidelines.

Software & Data Management

The KBC-82A operates as a standalone instrument with no proprietary software dependency. All parameters are set and monitored via the built-in LED display and tactile interface. For laboratories requiring audit trails or remote monitoring, optional RS-485 or USB-to-serial adapters enable integration into existing Lab Information Management Systems (LIMS) or SCADA platforms using Modbus RTU protocol. Logged data—including start time, duration, target speed, actual speed (±2 rpm accuracy), setpoint temperature, and chamber temperature (±0.5 °C)—can be exported for CSV-based analysis. The device supports 21 CFR Part 11–compliant electronic record workflows when paired with validated third-party data acquisition software that enforces user authentication, electronic signatures, and immutable audit logs.

Applications

• Mammalian and insect cell suspension culture in vented-cap flasks and bioreactor bags
• Bacterial and yeast fermentation kinetics studies under defined thermal regimes
• Antibiotic susceptibility testing (AST) via broth microdilution with continuous agitation
• Immunoassay plate washing and coating steps requiring gentle orbital motion
• Solubility profiling of APIs and excipients across temperature gradients
• DNA/RNA hybridization and probe binding optimization in hybridization ovens
• Environmental microbiology: water sample enrichment and dilution series preparation

FAQ

Is the KBC-82A suitable for CO₂-controlled environments?
No—it lacks gas-tight sealing or CO₂ sensor integration. Use only in ambient-air or externally regulated incubator chambers.
Can it accommodate stacked multiplate carriers?
Yes, provided total height does not exceed 180 mm and center of gravity remains within platform boundaries; verify mechanical stability at ≥250 rpm.
What is the calibration interval recommendation?
Annual verification of temperature accuracy (using NIST-traceable thermometer) and speed accuracy (via optical tachometer) is advised per ISO/IEC 17025 Annex A.
Does it support ramping profiles (e.g., gradual speed increase)?
No—this model implements step-change programming only. For ramped protocols, consider Langbo’s KBC-82P variant with PID-controlled acceleration/deceleration.
Is firmware upgrade capability available?
Firmware updates are performed exclusively by authorized Langbo service centers using JTAG interface; end users cannot modify firmware independently.
