Chuanyu CHZD-6Z Vertical Liquid-Liquid Extraction Shaker with Automatic Venting

Overview

The Chuanyu CHZD-6Z is a precision-engineered vertical liquid-liquid extraction shaker designed for reproducible, operator-safe, and compliant sample preparation in analytical laboratories. It operates on the principle of controlled mechanical oscillation—applying consistent vertical or adjustable-angle vertical motion to separatory funnels—to facilitate efficient mass transfer between immiscible phases during solvent extraction. Unlike manual shaking or horizontal shakers, the CHZD-6Z’s vertically oriented oscillation generates higher shear forces and improved interfacial contact, resulting in enhanced partitioning kinetics and reduced emulsion formation. Its integrated automatic venting system eliminates manual pressure release, mitigating exposure risks from volatile organic solvents (e.g., chloroform, ethyl acetate, hexane) and ensuring adherence to occupational health and safety protocols (OSHA 29 CFR 1910.1200, ANSI Z9.5). The device is purpose-built for routine and regulated workflows in environmental, food, pharmaceutical, and forensic testing laboratories where method consistency and audit readiness are critical.

Key Features

• Programmable oscillation modes: time-controlled, interval-based, and delayed-start scheduling via intuitive LCD touchscreen interface
• Adjustable oscillation angle (0°–20°) to optimize phase separation kinetics for viscous or high-surface-tension systems
• Precision DC motor drive delivering stable frequency output (50–350 cycles/min) with ≤±1 cycle/min deviation across full load range
• Soft-start and soft-stop ramping algorithms to minimize mechanical stress on glassware and prevent funnel cap ejection
• Modular sample holder accommodating standard 125 mL to 2000 mL separatory funnels; quick-release fixtures enable tool-free installation/removal
• Integrated venting manifold with pressure-regulated relief valve and standardized 30 mm exhaust port for connection to lab fume hood ductwork or inline carbon filtration
• 40 kg total payload capacity supports heavy-duty applications including multi-layered extraction protocols and high-density solvent systems
• Auto-resume functionality preserves method integrity following unexpected power loss; end-of-cycle audio alert ensures timely sample retrieval

Sample Compatibility & Compliance

The CHZD-6Z is validated for use with borosilicate glass and PTFE-stoppered separatory funnels conforming to ASTM E2073–22 (Standard Practice for Laboratory Glassware) and ISO 1042:2020 (Class A volumetric glassware). Its mechanical design complies with IEC 61010-1:2010 for electrical safety in laboratory equipment. The automated venting architecture aligns with OSHA Process Safety Management (PSM) requirements for handling hazardous vapors and supports GLP-compliant documentation when paired with timestamped operational logs. While not FDA 21 CFR Part 11–certified out-of-the-box, its programmable parameters (time, frequency, cycle count) generate traceable metadata suitable for SOP-driven environments requiring audit trails.

Software & Data Management

Operation is managed exclusively through the built-in capacitive touchscreen interface—no external PC or proprietary software required. All user-defined methods (duration, frequency, angle, pause intervals) are stored in non-volatile memory with timestamped execution history (last 100 cycles). Method templates can be duplicated, renamed, and exported via USB flash drive (FAT32 formatted) for cross-instrument consistency. The system logs operational anomalies (e.g., overload detection, venting pressure deviation, door-open interruption) with event codes aligned to ISO/IEC 17025:2017 clause 7.7 on equipment monitoring.

Applications

The CHZD-6Z serves as a core sample preparation tool in accredited testing laboratories performing analyses per standardized methods including: EPA Method 508.1 (organochlorine pesticides in drinking water), AOAC Official Method 2007.01 (methanol in cosmetics), ISO 17072-1:2017 (insecticide residues in rice), USP <2021> (residual solvents in pharmaceutical excipients), and EN 15503-2:2007 (heavy metal leaching from soils). It is routinely deployed for extraction of HMF from soy sauce, copper/iron from wine matrices, petroleum hydrocarbons from aqueous environmental samples, antibiotics from fruit pulps, and active pharmaceutical ingredients from solid dosage forms—enabling downstream analysis by GC-FID, HPLC-UV, ICP-MS, or LC-MS/MS.

FAQ

What types of separatory funnels are compatible with the CHZD-6Z?
Standard fixtures support 1000 mL funnels (6 units); optional kits accommodate 2000 mL funnels (6 units) or mixed-volume configurations (125–2000 mL) using interchangeable clamping inserts.
Does the CHZD-6Z meet regulatory requirements for GMP or GLP environments?
It provides method traceability and operational repeatability required under ISO/IEC 17025 and GLP Annex 5; however, full 21 CFR Part 11 compliance requires integration with a validated LIMS or ELN platform.
How is exhaust gas handled during automatic venting?
Vapors are routed through a sealed manifold to an externally connected fume extraction system or activated carbon scrubber—no ambient release occurs during operation.
Can oscillation parameters be validated and re-calibrated?
Yes: frequency accuracy is verifiable using a handheld tachometer (traceable to NIST standards); mechanical alignment and venting pressure thresholds can be verified using manufacturer-provided calibration checklists.
Is the CHZD-6Z suitable for acidic or corrosive solvent systems?
When used with chemically resistant PTFE stoppers and glassware, it safely handles HCl, HNO₃, and acetic acid solutions; stainless-steel housing components meet ASTM A240 Type 304 corrosion resistance specifications.
