Glucose-Glutamic Acid (GGA) Standard
Manufacturer: LabChem Inc.
Glucose-Glutamic Acid (GGA) from LabChem Inc. is a critical analytical reagent used primarily as a standard check solution in Biochemical Oxygen Demand (BOD₅) testing. This solution contains a precise 1:1 mixture of Glucose and Glutamic Acid, designed to provide a known biodegradable organic load for measuring the "health" and efficiency of the seed bacteria used in wastewater analysis. In accordance with Standard Methods for the Examination of Water and Wastewater, this reagent allows laboratories to verify that their BOD testing environment, seed, and dilution water are producing accurate and reproducible results (typically targeting a BOD value of 198 ± 30.5 mg/L).

Lead Times May Vary.
We offer GGA in both bulk bottles and convenient single-use 6 mL vials to minimize contamination risk and eliminate pipetting errors.
Features:- Verification of Seed Potency: Essential for determining if the microorganisms in your BOD test are viable and capable of breaking down organic matter at the expected rate
- Manufactured with ultra-pure reagents to ensure no background interference or toxic inhibitory effects on the bacterial seed
- Pre-prepared to exact concentrations, saving labor-intensive preparation time and reducing the risk of calculation or weighing errors
- Sterile Vials Available: The 6 mL vial format (Catalog #LC14845246) is ideal for high-compliance labs, ensuring a fresh, uncontaminated standard for every batch of BOD bottles
Safety & Regulatory Information:
WARNING! Chemical Hazard: GGA is highly susceptible to biological degradation.
- Refrigeration: Store at 2°C to 8°C to maintain the integrity of the solution.
- Handling: Use aseptic techniques when dispensing from bulk bottles. If the solution becomes cloudy or develops visible growth, it must be discarded.
- Personal Protection: Wear nitrile gloves and safety glasses. While generally non-toxic, follow standard lab safety protocols.
- Note on Use: For a standard 300 mL BOD bottle, typically 6 mL of this GGA solution is added to achieve the required concentration for the check test.
