Reciprocating homogenizer LTH-201

back-and-forthbenchtopcompact

Product Overview
The Stomacher LTH-201 is a bench-top laboratory homogenizer designed for fast, sterile and reproducible sample preparation in microbiological, clinical and research laboratories. The unit processes samples directly within disposable sterile homogenization bags to minimize cross-contamination and maintain sample integrity. Programmable microprocessor control supports up to eight user-defined programs with adjustable homogenization speed (3–12 strokes/second), adjustable flapping distance (0–50 mm), and timing from 0.1 s up to 99 h 59 min 59 s, including continuous operation. The instrument accommodates sample volumes from 3–400 mL, features a 4.3-inch color touch-screen interface and includes integrated heating sterilization and UV disinfection functions for a hygienic chamber.

Key Benefits

• Sterile sample processing using disposable homogenization bags to reduce cross-contamination and simplify cleanup.
• Programmable operation with up to eight user-definable methods for consistent, repeatable results.
• Integrated heating and UV disinfection for in-chamber sterilization and improved hygiene control.

Features

• Heating capability from room temperature up to 60°C and chamber sterilization function.
• Paddle-based homogenization that compresses samples inside disposable bags without direct contact with instrument surfaces.
• Microcomputer control with 8-segment combined programming for flexible process sequencing.
• Adjustable flapping distance (0–50 mm) to optimize homogenization for different sample types.
• Automatic safety door interlock with anti-pinch and anti-collision protection.
• Soft-start technology to reduce mechanical shock at startup.
• Pause-and-resume function to interrupt processes without losing program settings.
• Voice prompts and end-of-cycle audible alarm for operator convenience.
• Durable stainless-steel chamber with anti-corrosion powder coating.
• Compact benchtop design with touch-screen interface for quick parameter adjustment and monitoring.

Applications

• Food microbiology: preparation of samples for microbiological analysis, pathogen detection and QC testing.
• Pharmaceutical testing: homogenization for microbiological and analytical workflows.
• Clinical diagnostics: processing biological specimens for microbiology and diagnostic procedures.
