Product Overview
A thermostatic metal bath, also known as a dry bath, dry-block heater, or constant-temperature metal bath, delivers uniform dry-block heating and mixing for microtubes, PCR tubes, microplates, and other small-volume containers in molecular biology, clinical chemistry, and analytical laboratories. BKMAMLAB Labshark thermostatic metal baths come in four configurations: SMB-MH (heating and oscillation), SMB-FC (programmable heating and cooling with timing), SMB-C (heating and cooling, no programming), and SMB-H (heating only, no programming).
Key Features & Advantages
- Four model configurations: SMB-MH (heating + oscillation), SMB-FC (programmable heating + cooling with timing), SMB-C (heating + cooling), SMB-H (heating only).
- Microcomputer-based PID control: Delivers ±0.1°C temperature-control accuracy with low temperature fluctuation.
- DC brushless motor drive: Long service life with stable, quiet oscillation (oscillation models).
- Interchangeable sample modules: Supports volumes from 1 mL to 50 mL in formats including 96-well plate, 0.2 mL, 0.5 mL, 1.5 mL, 2.0 mL, 5 mL, 10 mL, 15 mL, and 50 mL.
- Flexible timing: Culture time can be set from 1 minute to 99 hours 59 minutes.
- Dual voltage options: 110 V or 220 V configurations available.

Comparison & Competitive Advantages
Unlike water baths that risk sample contamination from waterborne pathogens and spillage, the BKMAMLAB Labshark thermostatic metal bath provides clean, dry-block heating with no liquid medium. Compared to basic dry-block heaters that offer heating only, the SMB-FC model provides programmable heating and cooling with precise timing, eliminating the need for separate heating and cooling instruments. The ±0.1°C accuracy exceeds the precision of most competing dry baths in the same price range, making it suitable for sensitive enzymatic and nucleic-acid amplification workflows.
Applications
Ideal for enzyme reactions, immunoassays, nucleic-acid amplification setup, sample preservation, gene synthesis, hybridization reactions, phase-change studies, and laboratory temperature-controlled incubation. Suitable for laboratory research, bioengineering, pharmaceutical development, and scientific-research education environments.
Frequently Asked Questions
Q: What is a thermostatic metal bath and what is it used for?
A: A thermostatic metal bath (dry bath) is a laboratory instrument that uses heated metal blocks to uniformly warm samples in microtubes, PCR tubes, and microplates. It is used for enzyme reactions, immunoassays, nucleic-acid amplification setup, sample preservation, and temperature-controlled incubation without the contamination risks of water baths.
Q: What is the difference between the BKMAMLAB Labshark SMB-MH and SMB-FC models?
A: The SMB-MH provides heating with oscillation (mixing), making it ideal for reactions requiring simultaneous temperature control and sample agitation. The SMB-FC offers programmable heating and cooling with timing, making it suitable for protocols that require precise temperature ramping and cycling.
Q: What sample module formats are compatible with the thermostatic metal bath?
A: The thermostatic metal bath accepts interchangeable modules for 96-well plates, 0.2 mL, 0.5 mL, 1.5 mL, 2.0 mL, 5 mL, 10 mL, 15 mL, and 50 mL tubes. Modules can be swapped without tools to accommodate different experimental needs.
Q: What is the temperature-control accuracy of the thermostatic metal bath?
A: The BKMAMLAB Labshark thermostatic metal bath achieves ±0.1°C temperature-control accuracy using microcomputer-based PID control, making it suitable for sensitive enzymatic reactions and nucleic-acid amplification workflows.
