TTL TTL-800 Extraction & Purification Shaker for Separatory Funnels

Overview

The TTL TTL-800 Extraction & Purification Shaker is an engineered benchtop platform designed specifically for reproducible, high-efficiency liquid-liquid extraction and sample cleanup workflows in analytical chemistry, environmental testing, food safety, and pharmaceutical QC laboratories. Unlike general-purpose orbital shakers, the TTL-800 implements a dual-mode mechanical drive system—capable of both vertical reciprocating motion and user-adjustable inclined oscillation—to optimize phase mixing kinetics in separatory funnels. Its operation relies on controlled inertial displacement of aqueous-organic biphasic systems, enhancing interfacial contact area and mass transfer rates while minimizing emulsion formation and funnel pressure buildup. The device operates at ambient temperature only and is not equipped with active heating or cooling; its robust aluminum-alloy frame and precision-machined cam mechanism ensure long-term mechanical stability under continuous duty cycles typical of multi-sample batch extractions.

Key Features

• Dual oscillation modes: Selectable vertical reciprocation (for gentle phase separation) or adjustable inclination (0°–30°) to intensify mixing energy—enabling method-specific optimization for diverse solvent systems (e.g., dichloromethane/water, ethyl acetate/hexane, or MTBE/aqueous buffer).
• Four independently mounted shaker platforms, each accommodating up to two standard 1–2 L glass separatory funnels (total capacity: 8 funnels), with quick-release universal clamps compatible with conical, pear-shaped, and cylindrical funnel geometries.
• Digitally controlled brushless DC motor delivering smooth, low-noise (<55 dB[A]) operation across the full 0–300 rpm range, with real-time rpm readout and fine-resolution speed adjustment (1 rpm increments).
• Programmable digital timer (0–60 minutes) with auto-shutdown and audible alert; memory retention preserves last-used settings after power interruption.
• Rotatable sample carrier assembly allows 360° horizontal rotation for ergonomic loading/unloading without repositioning the instrument—critical for high-throughput labs handling heavy or volatile solvent systems.
• Modular accessory support: Optional funnel holders for 250 mL, 500 mL, 1 L, and 2 L capacities; PTFE-coated clamp liners for chemical resistance; and anti-slip silicone base pads for vibration isolation on shared lab benches.

Sample Compatibility & Compliance

The TTL-800 accommodates standard borosilicate glass separatory funnels (ISO 17761-compliant dimensions) and select polypropylene alternatives rated for organic solvents. It supports common extraction protocols aligned with EPA Method 3510C (liquid-liquid extraction), ASTM D7089 (petroleum hydrocarbon analysis), and AOAC 996.06 (pesticide residue cleanup). While the unit itself carries no CE or UL certification, its electrical design conforms to IEC 61010-1:2010 safety requirements for laboratory equipment. For GLP/GMP-regulated environments, users may integrate the TTL-800 into validated workflows using external audit-trail-capable timers or connect it to LIMS via optional RS-232 interface (available upon request).

Software & Data Management

The TTL-800 operates as a standalone hardware platform with no embedded software or network connectivity. All operational parameters—speed, time, and mode—are set locally via front-panel membrane keys and displayed on a 3-digit LED screen. For traceability in regulated settings, laboratories commonly pair the shaker with electronic lab notebooks (ELNs) or chromatography data systems (CDS) that log instrument usage metadata (e.g., timestamped start/stop events, operator ID, protocol version). TTL provides a complete calibration certificate (including speed accuracy verification at 100/200/300 rpm) and maintenance log template compliant with ISO/IEC 17025 documentation standards.

Applications

• Preparative cleanup of environmental water samples prior to GC-MS analysis of PAHs, PCBs, and organochlorine pesticides.
• Residue extraction from food matrices (e.g., fruits, vegetables, meat homogenates) per EU SANTE/11813/2021 guidelines.
• Pharmaceutical impurity isolation during forced degradation studies and stability-indicating method development.
• Metabolite recovery from cell culture supernatants or plasma extracts in early-stage drug discovery pipelines.
• Standardization of manual shaking procedures in method transfer between R&D and QC labs, reducing inter-operator variability by >65% (based on internal repeatability studies).

FAQ

Is the TTL-800 suitable for use with volatile or corrosive solvents?
Yes—when used with chemically resistant funnels and PTFE-lined clamps (recommended accessory), it safely handles chlorinated solvents (e.g., DCM, chloroform), esters (ethyl acetate), and aliphatic hydrocarbons. Avoid prolonged exposure to strong oxidizers (e.g., nitric acid) or halogenated fluorocarbons.
Does the instrument include temperature control?
No—the TTL-800 is an ambient-only shaker. For thermally sensitive extractions requiring precise temperature management, integration with external cold/hot rooms or use of pre-chilled funnels is advised.
Can I run fewer than eight funnels without affecting performance?
Yes—load imbalance is mechanically compensated by the counterweighted drive system. However, symmetric placement (e.g., 2 or 4 funnels evenly distributed) is recommended to minimize bearing wear over extended operation.
What maintenance is required?
Biannual inspection of cam follower lubrication and clamp torque verification; annual recalibration of speed display against a certified tachometer is recommended for ISO/IEC 17025 compliance.
Is technical support available outside China?
TTL provides English-language documentation, remote troubleshooting via email, and application guidance through authorized regional distributors in North America, EU, and Southeast Asia—support contracts include firmware updates and spare parts logistics.
