Thermo Scientific Lindberg Blue M 26.5 L Shaker Water bath

Thermo Scientific Lindberg Blue M 26.5 L Shaker Water Bath (SWB1122A-1) – Reciprocating Motion

The Thermo Scientific Lindberg Blue M SWB1122A-1 is an industrial-grade, constant-temperature shaking water bath engineered for precise sample tempering and uniform biological agitation. Featuring a 26.5-liter (7 gallon) fluid capacity, this robust system provides a heavy-duty reciprocating stroke mechanism alongside advanced microprocessor temperature regulation. Built with a high-durability stainless steel interior and cabinet, it is designed to maintain strict process validation benchmarks in molecular biology, cell culture, tissue metabolism, and chemical solubility workflows.

Technical Performance & Design

• High-Uniformity Microprocessor Control: Utilizes a digital PID controller that automatically monitors and adjusts heating parameters, delivering a remarkable temperature uniformity of ±0.1°C up to boiling points.
• Adjustable Reciprocating Stroke: Features a smooth reciprocating shaking action with an adjustable frequency up to 200 strokes per minute, paired with a mechanically adjustable stroke length ranging from 7/8 to 1-1/2 inches.
• Premium Stainless Steel Construction: Crafted with a Type 304 polished stainless steel interior chamber and a rugged exterior cabinet, offering exceptional resistance to corrosion, pitting, and aggressive chemical cleanings.
• Independent High-Limit Safety: Equipped with a user-adjustable, independent over-temperature safety circuit that instantly removes power from the 1400-watt heating element if a thermal runaway condition occurs.

Key Benefits & Applications

• High-Throughput Hybridization & Culturing: The broad 18x12-inch chamber accommodates a substantial volume of Erlenmeyer flasks, test tubes, or media bottles, making it ideal for large-batch bacterial incubations.
• Consistent Mass Transfer Rates: Adjustable stroke geometries allow technicians to precisely regulate the shear forces applied to cells or delicate tissue cultures during metabolic extraction runs.
• Low-Maintenance Architecture: Engineered with accessible drive links and a seamless internal pan design that eliminates common grime-catching corners, simplifying routine sanitation routines.
• High-Temperature Process Stability: Optimized to prevent evaporation heat-loss during long-term continuous runs, particularly when paired with a stainless steel gabled cover for operations exceeding 75°C.
