MENTS MB100-4A Microplate Incubator Shaker

Overview

The MENTS MB100-4A Microplate Incubator Shaker is an integrated benchtop instrument engineered for precise temperature-controlled orbital shaking of standard microtiter formats. It combines PID-based digital temperature regulation with high-efficiency DC brushless motor drive to deliver stable thermal environments and reproducible agitation across up to four independent microplate platforms simultaneously. Designed specifically for life science workflows requiring synchronized incubation and mixing—such as ELISA development, cell-based assays, microbial growth studies, and nucleic acid hybridization—the MB100-4A operates on the principle of horizontal orbital motion (2 mm diameter), ensuring uniform suspension of adherent or suspended cells without shear-induced damage. Its compact footprint (280 × 270 × 140 mm) and low power consumption (150 W) make it suitable for shared lab spaces, biosafety cabinets, and continuous-use applications under GLP-compliant conditions.

Key Features

• Four independently accessible, interchangeable shaking platforms—compatible with ANSI/SLAS-standard 96-well, 384-well, deep-well, and cell culture plates.
• PID-controlled heating system with dual-layer thermal insulation and real-time feedback loop, achieving ≤ ±0.5 °C temperature accuracy and ≤0.1 °C display resolution.
• DC brushless motor delivering smooth, maintenance-free operation across a wide speed range (200–1600 rpm) with noise level <45 dB(A) at 1000 rpm.
• Intuitive single-knob interface with backlit LCD panel showing real-time temperature, speed, and remaining time; supports parameter locking to prevent accidental changes during long-duration runs.
• Programmable timer from 1 minute to 99 hours 59 minutes, with audible alert and automatic shutdown upon completion.
• Fast thermal ramping: reaches 80 °C from ambient in ≤20 minutes, minimizing assay downtime between experimental cycles.

Sample Compatibility & Compliance

The MB100-4A accommodates standard SBS-format microplates including flat-bottom, U-bottom, V-bottom, and skirted variants used in enzymatic assays, stem cell expansion, bacterial culture, and immunoassay optimization. All contact surfaces are constructed from corrosion-resistant stainless steel and chemically inert polymers compatible with common laboratory solvents (e.g., 70% ethanol, isopropanol). The instrument meets IEC 61010-1 safety requirements for laboratory electrical equipment and conforms to electromagnetic compatibility standards EN 61326-1. While not certified for clinical diagnostics use, its thermal stability and timing repeatability support method validation per ISO/IEC 17025 guidelines when operated within defined environmental limits (ambient temperature 15–30 °C, relative humidity ≤80% non-condensing).

Software & Data Management

The MB100-4A operates as a standalone instrument with no embedded software or network connectivity. All operational parameters are set locally via the front-panel interface, eliminating cybersecurity risks associated with connected devices. For laboratories implementing electronic record-keeping systems (e.g., LIMS or ELN), manual entry of run parameters—including start time, target temperature, set speed, and duration—is recommended for audit trail completeness. The device supports GxP-aligned documentation practices through consistent timestamped operator logs and physical labeling of processed plates. Though lacking FDA 21 CFR Part 11-compliant electronic signatures, its deterministic behavior and absence of firmware-updatable logic render it inherently suitable for regulated QC/QA environments where procedural controls govern data integrity.

Applications

• Enzyme-linked immunosorbent assay (ELISA) plate washing and incubation steps requiring uniform antigen–antibody interaction kinetics.
• Adherent mammalian cell culture maintenance during transfection or drug screening, where gentle agitation prevents detachment while enhancing nutrient diffusion.
• Microbial suspension culture in 96-well deep-well blocks for high-throughput antibiotic susceptibility testing.
• Hybridization protocols involving DNA probes and membrane-bound targets, where controlled temperature and orbital mixing improve binding efficiency.
• Protein crystallization trials using sitting-drop or hanging-drop configurations on heated shaker platforms to modulate supersaturation dynamics.

FAQ

Can the MB100-4A accommodate 384-well plates?
Yes—each platform accepts ANSI/SLAS-compliant 384-well microplates, provided they are rigid enough to maintain structural integrity at speeds up to 1600 rpm.
Is condensation control available inside the chamber?
No—the MB100-4A does not include active humidity regulation or anti-condensation features; users should seal plates with breathable adhesive films or use desiccant packs when operating above ambient dew point.
What is the maximum load per platform?
Each platform supports up to 1.5 kg gross weight, sufficient for four standard 96-well plates filled with aqueous solutions (~200 µL/well).
Does the unit support external temperature probes for verification?
The instrument lacks auxiliary sensor ports; however, external calibrated thermistors or RTDs may be placed adjacent to sample wells during IQ/OQ qualification without interfering with orbital motion.
Can the shaking direction be reversed or adjusted to linear motion?
No—it operates exclusively in fixed horizontal orbital mode (2 mm diameter); no programmable axis selection or waveform modulation is available.
