Reciprocating homogenizer LTH-201

back-and-forthcompactbenchtop

Product overview
The Labotemp Stomacher LTH-201 is a benchtop stomacher homogenizer designed for fast, sterile and reproducible sample preparation in microbiology, clinical and research laboratories. The unit processes samples directly inside sterile disposable homogenization bags to minimize cross-contamination while preserving sample integrity. Programmable microprocessor control supports up to 8 user-defined programs with adjustable speed (3–12 strokes/s), flapping distance (0–50 mm) and timing from 0.1 s up to 99 h 59 min 59 s. The instrument accommodates sample volumes from 3–400 mL and includes a 4.3-inch color touchscreen, integrated heating sterilization and UV disinfection for hygienic chamber control.

How it works
The LTH-201 uses a paddle-based homogenization mechanism that compresses samples inside disposable bags without direct contact with the instrument. Adjustable flapping distance and programmable modes allow optimization for different sample types. Automatic door interlock, anti-pinch safety stop and soft-start protect operators and delicate samples. Disposable bag workflow eliminates chamber cleaning between samples, reducing turnaround time and contamination risk.
