Dry Bath

• A dry bath is a laboratory instrument used to heat samples.
• It uses a heated metal block to transfer heat to the samples, unlike a water bath which uses a water medium.

Why Use a Dry Bath?

• Versatility: Dry baths can accommodate a wide variety of sample containers, including tubes, vials, and microplates.  
• Temperature Control: They offer precise temperature control, allowing for accurate heating of samples.  
• Dry Environment: Ideal for samples that cannot be exposed to water or moisture.
• Safety: Eliminates the risk of spills or contamination associated with water baths.

Common Applications

• Molecular Biology:
  • DNA denaturation
  • Enzyme reactions  
  • PCR sample preparation
• Microbiology:
  • Bacterial culture incubation
  • Media preparation
• Biochemistry:
  • Protein denaturation
  • Enzyme assays  
• Genetics:
  • DNA hybridization
  • Gel electrophoresis sample preparation

Key Features to Consider

• Temperature Range: Ensure it covers the required temperature range for your applications.  
• Block Capacity: Choose a block size that accommodates your sample volume.
• Temperature Uniformity: Look for models with even heat distribution across the block.
• Timer: A built-in timer is helpful for timed incubations.  
• Microprocessor Control: Provides precise temperature control and easy programming.
