Thermo Scientific TSSWB27 Precision 27L Shaking Bath

The Thermo Scientific TSSWB27 Precision 27L Digital Lab Shaking Water Bath is engineered for laboratory workflows requiring uniform thermal regulation combined with controlled mechanical agitation. With a generous 27-liter chamber capacity, this benchtop unit accommodates high-throughput sample batches, larger flasks, and diverse rack configurations while maintaining precise process control.

Thermo Scientific TSSWB27 Key Technical Specifications

• Chamber Capacity: 27 liters (approx. 7.1 gallons), providing ample space for high-volume incubation.
• Temperature Range: Ambient +5°C to 100°C (when operated with the included gabled stainless steel lid).
• Thermal Uniformity: ±0.05°C at 37°C, ensuring consistent heat distribution across all samples.
• Shaking Motion: Reciprocating orbital/linear agitation, adjustable from 30 to 200 oscillations per minute (OPM).
• Stroke Length: Adjustable stroke settings (typically 0.5 in. to 1.0 in.) to tailor agitation intensity to shear-sensitive samples.
• Control System: Microprocessor-controlled digital interface with dual LED displays for setpoint and actual process values.
• Chamber Construction: Seamless, corrosion-resistant 304 stainless steel interior with an external front-mounted drain port for rapid cleaning.

Design and Operational Features

The TSSWB27 features a durable heating element beneath the chamber floor. Consequently, this design eliminates fluid contact and avoids hot spots. Furthermore, perimeter heating works alongside natural fluid circulation to maintain stable thermal equilibrium throughout the bath.

The gabled lid also prevents condensation from dripping directly onto sample vessels by channeling moisture down the walls. In addition, an independent over-temperature cut-off protects sensitive samples, while low-water-level sensors prevent dry-run damage.

Target Applications

The combination of digital temperature stability and continuous mechanical shaking makes the TSSWB27 well-suited for demanding research, clinical, and industrial environments:

• Cell Culture & Microbiology: Culturing bacteria, yeast, and tissue samples requiring continuous oxygenation and thermal consistency.
• Molecular Biology: Hybridization assays, DNA extraction protocols, and enzymatic digestions.
• Biochemical Assays: Protein solubility studies, reagent incubation, and controlled chemical reactions.
• General Lab Procedures: Gentle thawing of cryovials, reagent warming, and general sample dissolution.

Overall, the Thermo Scientific TSSWB27 features a quiet drive mechanism and user-friendly digital calibration. Therefore, its rugged stainless steel construction makes it a dependable workhorse for academic, pharmaceutical, and industrial testing facilities requiring repeatable experimental conditions.
