CZGY CZ-D2L Adjustable-Angle Partition Funnel Shaker

Overview

The CZGY CZ-D2L Adjustable-Angle Partition Funnel Shaker is an engineered solution for liquid–liquid extraction workflows in analytical and environmental laboratories. It operates on the principle of controlled orbital oscillation with variable tilt-angle adjustment (0–20°), enabling optimized phase separation kinetics during solvent extraction procedures. Unlike standard horizontal shakers, its inclined oscillation path enhances interfacial contact area and mass transfer efficiency between immiscible phases—critical for trace analyte recovery in EPA Method 508, ISO 10302, and USP <467> residual solvent analyses. Designed as a functional evolution of legacy HY-1 systems, the CZ-D2L integrates modern microprocessor-based motion control while retaining mechanical robustness for sustained operation under repetitive high-load conditions (up to 12 kg total payload). Its ambient-only operation makes it suitable for non-temperature-sensitive extractions where thermal degradation of analytes must be avoided.

Key Features

• Microprocessor-controlled speed regulation with digital RPM display and ±1 rpm accuracy across full 40–350 rpm range
• Adjustable inclination angle (0–20°) for tunable shear profile and improved emulsion breakdown
• Six independent, vertically aligned oscillation platforms with integrated quick-release clamping mechanism
• Ergonomic one-piece elastic clamp system accommodating volumetric glassware from 150 mL to 1000 mL partition funnels without tooling
• DC motor drive with low-noise brushless architecture ensuring stable frequency output over extended duty cycles
• Power-fail recovery function and auto-shutdown at timer completion compliant with GLP documentation requirements
• Electrostatically coated steel housing with corrosion-resistant finish for long-term durability in humid or solvent-rich lab environments
• Front-panel intuitive interface: up/down keys for parameter entry, RUN/STOP toggle, zero-time mode for continuous operation

Sample Compatibility & Compliance

The CZ-D2L accommodates standard laboratory glassware including stoppered volumetric flasks (100–1000 mL), graduated cylinders, colorimetric tubes, Erlenmeyer flasks (up to 1000 mL), centrifuge tubes, and calibrated pipettes. Its universal clamping geometry supports both conical and cylindrical geometries without adapter kits. The instrument complies with IEC 61010-1:2010 safety standards for laboratory electrical equipment and meets electromagnetic compatibility (EMC) Class B limits per EN 61326-1. While not temperature-controlled, its ambient-only design aligns with ASTM D3412 and ISO 11348 protocols requiring isothermal extraction conditions. All electrical components are CE-marked and rated for continuous 220 V / 50 Hz operation.

Software & Data Management

The CZ-D2L operates as a standalone hardware platform with no embedded software or network connectivity. Parameter settings—including speed, tilt angle (mechanically preset), and timer duration—are retained in non-volatile memory after power cycling. Digital display logs current RPM and remaining time in real time. For regulated environments, manual entry into laboratory notebooks or LIMS systems satisfies 21 CFR Part 11 audit-trail requirements when paired with operator-signed run records. Optional external data loggers (e.g., Omega OM-DAQPRO-5300) may be interfaced via analog voltage output (0–5 V) for time-stamped RPM monitoring.

FAQ

What is the maximum load capacity per platform?
Each platform supports up to 2 kg, with a total instrument payload limit of 12 kg.
Can the tilt angle be adjusted during operation?
No—angle adjustment requires manual mechanical repositioning before startup and is not dynamically controllable.
Is the timer resolution programmable in seconds or minutes?
Timer resolution is 1 minute; the device does not support sub-minute increments.
Does the unit include calibration certificates or traceable documentation?
Factory calibration data for speed accuracy (±1 rpm) is provided with shipment; third-party NIST-traceable calibration is available upon request.
Are replacement clamps or platform inserts available separately?
Yes—CZGY supplies OEM part numbers CLAMP-CZD2L and PLATE-6P for field service and maintenance.
