Raymetech MMS100 Manual Micro-Manipulation Arm

Overview

The Raymetech MMS100 is a fully manual, high-stability mechanical micromanipulator engineered for precise positioning and manipulation of microscale objects under optical microscopy. Designed for integration with inverted or upright research-grade microscopes, the MMS100 operates on a robust lever-and-screw actuation principle—leveraging calibrated micrometer drives and low-backlash kinematic linkages to deliver sub-micrometer repeatability in X, Y, and Z axes. Unlike motorized or piezoelectric systems, its purely mechanical architecture eliminates electromagnetic interference, power dependency, and software latency—making it ideal for electrophysiology patch-clamp rigs, single-cell injection platforms, and fluorescence imaging setups where signal integrity and operational simplicity are paramount. The system conforms to standard microscope stage mounting protocols (36 mm dovetail or M4/M6 threaded base), enabling rapid deployment in GLP-compliant core facilities and academic physiology labs.

Key Features

• Three-axis orthogonal translation with independent coarse (10 mm range, 1 mm/rev) and fine (5 mm range, 10 µm/rev) adjustment dials per axis
• Anodized aluminum alloy frame with hardened stainless steel lead screws and brass bushings—optimized for thermal stability and long-term dimensional retention
• Zero-play gimbal joint design at the manipulator tip ensures minimal angular drift during extended positional holding
• Modular toolholder compatibility: accepts standard 1.0 mm OD glass capillaries, tungsten microelectrodes, fiber-optic probes, and custom-fabricated microtools via interchangeable collet sleeves
• No external power, controllers, or drivers required—fully functional out-of-the-box with microscope alignment verification
• Calibrated scale markings on all micrometer drums with engraved reference lines for traceable manual positioning

Sample Compatibility & Compliance

The MMS100 supports direct manipulation of biological specimens including oocytes, zygotes, blastomeres, primary neurons, organotypic brain slices, and adherent cell monolayers cultured on glass-bottom dishes or chambered coverslips. Its mechanical design avoids static charge accumulation and outgassing—critical for live-cell viability during prolonged (>2 hr) microinjection or patch-clamp experiments. The device meets ISO 13485-aligned manufacturing controls as implemented by Raymetech’s Jiangsu production facility. While not CE-marked as an active medical device, it complies with IEC 61000-6-2 (immunity) and IEC 61000-6-3 (emission) standards applicable to laboratory ancillary equipment. It is routinely validated in laboratories adhering to USP <1058>, CLSI EP26-A, and ISO/IEC 17025 quality frameworks for instrument qualification.

Software & Data Management

As a fully manual system, the MMS100 requires no proprietary software, firmware, or driver installation. All positional data is recorded manually via micrometer dial readings or synchronized with third-party acquisition platforms (e.g., MetaMorph, NIS-Elements, or Spike2) using analog trigger inputs or TTL-based event logging. For audit-trail compliance in regulated environments (e.g., preclinical pharmacology studies under FDA 21 CFR Part 11), users may document manipulator settings alongside image timestamps and experimental metadata in electronic lab notebooks (ELNs) such as LabArchives or Benchling. No embedded memory, network interface, or remote access capability is present—eliminating cybersecurity validation overhead.

Applications

• Reproductive Biology: Intracytoplasmic sperm injection (ICSI), blastomere biopsy for PGD/PGS, embryonic stem cell isolation, and zona pellucida drilling using sharpened beveled pipettes
• Neurophysiology: Stable positioning of patch pipettes for whole-cell recordings in acute brain slices; simultaneous placement of stimulating and recording electrodes in multi-electrode arrays
• Single-Cell Genomics: Targeted aspiration of cytoplasmic or nuclear content from individual cells for downstream RNA-seq or ATAC-seq library preparation
• Optogenetics & Photostimulation: Precise alignment of 405 nm/473 nm laser-coupled fibers onto defined neuronal subcompartments (dendritic spines, axon initial segments)
• Microfabrication Integration: Alignment of microfluidic chips, MEMS devices, or photonic waveguides relative to microscope objectives during optical characterization

FAQ

Is the MMS100 compatible with upright microscopes?
Yes—the base plate includes both 36 mm dovetail and M4 threaded mounting options, allowing secure attachment to most commercial upright and inverted microscope stages.
Can it be used inside a CO₂ incubator?
No—the aluminum and brass components are not rated for humidified 5% CO₂ environments; condensation may impair screw thread performance and accelerate oxidation.
What is the maximum recommended payload for sustained use?
200 g at the tip; exceeding this limit risks hysteresis in fine-adjustment response and reduces long-term repeatability beyond ±2 µm.
Does Raymetech provide calibration certificates?
Upon request, Raymetech issues a factory-as-tested report documenting micrometer linearity and axial orthogonality per ISO 9283, traceable to NIM (China National Institute of Metrology).
How is maintenance performed?
Annual cleaning of lead screws with isopropyl alcohol and re-lubrication with Dow Corning® Molykote® BR2 plus is recommended; no user-serviceable electronics or firmware exist.
