BD Bbl™ Catalase Reagent Droppers

The BD BBL™ Catalase Reagent Droppers are ready-to-use tools designed for the catalase test, a fundamental biochemical assay used to identify microorganisms based on their production of the enzyme catalase. These droppers simplify the testing process, making it convenient and reliable for clinical, environmental, and food microbiology applications.

Key Features

1. Ready-to-Use Format:
   • Pre-filled droppers eliminate the need for reagent preparation, reducing handling time and contamination risks.
2. Hydrogen Peroxide-Based Reagent:
   • Contains 3% hydrogen peroxide (H₂O₂), the standard reagent for catalase testing.
3. Single-Use Design:
   • Ensures sterility and accuracy by using a fresh dropper for each test.
4. Safe and Controlled Application:
   • Designed for direct application to bacterial colonies, ensuring precise reagent delivery without spillage.
5. Reliable Reaction:
   • Catalase-positive organisms produce visible bubbling or effervescence when the reagent reacts with hydrogen peroxide.

Specifications

Applications

1. Microbial Identification:

• Used to identify catalase-positive bacteria, including:
  • Staphylococci: Catalase-positive.
  • Streptococci: Catalase-negative.

2. Differentiation of Bacteria:

• Helps differentiate between bacterial genera based on their ability to produce the enzyme catalase.

3. Clinical Diagnostics:

• Assists in the identification of pathogens from clinical specimens for diagnostic purposes.

4. Food and Environmental Microbiology:

• Detects catalase activity in bacterial isolates from food and environmental samples.

5. Educational Use:

• An essential tool for teaching microbiology and bacteriology techniques in academic settings.

Testing Procedure

1. Sample Preparation:
   • Grow bacterial colonies on a suitable medium (e.g., blood agar) and ensure they are fresh for accurate results.
2. Application:
   • Remove a single-use dropper and apply 1–2 drops of the 3% hydrogen peroxide reagent directly onto the bacterial colony or a clean glass slide.
3. Observation:
   • Observe the reaction immediately:
     • Positive Result: Rapid effervescence (bubbling) indicates the presence of catalase.
     • Negative Result: No visible reaction.
4. Disposal:
   • Safely discard the used dropper according to laboratory waste protocols.
