XUEKE IMS-50 Laboratory Flake Ice Machine

Overview

The XUEKE IMS-50 Laboratory Flake Ice Machine is a compact, air-cooled refrigeration system engineered specifically for scientific and analytical laboratory environments where consistent, high-surface-area ice is essential for temperature-sensitive sample handling, enzymatic reactions, electrophoresis cooling, and reagent stabilization. Unlike cubed or nugget ice generators, the IMS-50 employs a direct-expansion evaporator drum design that freezes thin layers of water on a chilled stainless-steel surface; these layers are continuously scraped off by rotating augers to produce irregular, dendritic flake ice with particle sizes ranging from 1–3 mm in thickness and variable lateral dimensions (typically 5–15 mm). This morphology maximizes thermal contact area while minimizing mechanical stress on biological specimens—critical for applications such as tissue homogenization, PCR setup, and cold-chain sample transport within lab workflows. The unit utilizes an eco-friendly, non-CFC refrigerant and a sealed, low-noise rotary compressor rated for continuous duty cycles under ambient conditions up to 32 °C.

Key Features

• Microprocessor-controlled operation with LED status display, real-time cycle monitoring, and automatic defrost initiation based on evaporator temperature differentials
• Stainless-steel ice-making drum and auger assembly ensuring corrosion resistance, ease of cleaning, and compliance with ISO 13485-informed hygiene standards for lab-grade equipment
• Air-cooled condenser with intelligent fan modulation—reducing energy consumption during low-load periods without compromising ice output stability
• Integrated water-level sensor and overheat protection circuitry preventing dry-run operation and compressor thermal overload
• Front-access service panel enabling rapid filter replacement and routine maintenance without disassembly of structural components
• UL-listed electrical safety certification (IEC 61010-1) and CE marking for electromagnetic compatibility (EMC Directive 2014/30/EU)

Sample Compatibility & Compliance

The IMS-50 is designed for use with deionized (DI) or distilled water sources commonly employed in analytical laboratories. Its flake ice output exhibits negligible leaching of metallic ions or organic contaminants when fed with water meeting ASTM D1193 Type II specifications. While not classified as medical device hardware per FDA 21 CFR Part 820, the unit conforms to general laboratory equipment requirements outlined in ISO/IEC 17025:2017 Clause 6.4 (environmental conditions) and supports GLP-compliant documentation through time-stamped operational logs exported via optional RS-232 interface. It is compatible with standard laboratory water purification systems delivering flow rates ≥1.5 L/min at inlet pressures between 0.1–0.4 MPa.

Software & Data Management

The IMS-50 operates autonomously without external software dependencies. All operational parameters—including runtime hours, cumulative ice production, defrost frequency, and fault codes—are stored in non-volatile memory and accessible via the front-panel interface. For integration into centralized lab infrastructure, an optional RS-232 serial module enables connection to building management systems (BMS) or laboratory information management systems (LIMS), supporting ASCII-based command-response protocols for remote status polling and event-triggered alerts (e.g., low ice level, high condenser temperature). Audit trails generated by this interface comply with ALCOA+ principles when paired with validated LIMS configurations adhering to 21 CFR Part 11 requirements for electronic records.

Applications

• Cold preservation of enzyme solutions, antibodies, and nucleic acid extracts during benchtop preparation
• Temperature control in gel electrophoresis tanks and chromatography cold traps
• Sample cooling during mass spectrometry sample introduction and MALDI matrix application
• Pre-chilling of centrifuge rotors and microcentrifuge tubes prior to high-speed runs
• Supporting cryo-microtomy workflows by maintaining specimen blocks at stable sub-zero surface temperatures
• On-demand ice supply for QC/QA testing labs performing thermal validation studies per ISO/IEC 17025 Annex A.3

FAQ

What type of water should be used to ensure optimal performance and longevity?
Deionized or distilled water meeting ASTM D1193 Type II specifications is strongly recommended to prevent scale formation on the evaporator drum and minimize maintenance intervals.
Can the IMS-50 be installed under a laboratory counter?
Yes—the unit is designed for freestanding or under-counter installation, provided minimum rear clearance of 100 mm and top clearance of 150 mm are maintained for adequate airflow and heat dissipation.
Is the ice output suitable for direct contact with biological samples?
Flake ice produced by the IMS-50 is microbiologically inert when generated from purified water and handled using clean, dedicated scoops; however, end-users must validate sterility per their internal SOPs if aseptic conditions are required.
Does the unit support remote monitoring via Ethernet or Wi-Fi?
No native Ethernet or Wi-Fi capability is included; remote supervision is limited to RS-232 serial communication with third-party protocol adapters.
What is the expected service life of the compressor under typical lab usage?
When operated within specified ambient conditions (10–32 °C) and maintained per the manufacturer’s schedule, the sealed rotary compressor demonstrates a mean time between failures (MTBF) exceeding 30,000 operating hours.
