Laboratory Equip.. for BIS Compliance
Setting up a BIS-compliant water testing laboratory is essential for obtaining certification for packaged drinking water (IS 14543) or packaged natural mineral water (IS 13428). The Bureau of Indian Standards (BIS) mandates that such laboratories be equipped to conduct comprehensive physical, chemical, and microbiological analyses.
🧪 Essential Laboratory Equipment for BIS Compliance
- Physical & Chemical Testing Instruments
These instruments assess parameters like pH, turbidity, total dissolved solids (TDS), and chemical contaminants:
- pH Meter: Measures the acidity or alkalinity of water.
- Turbidity Meter: Assesses the clarity of water by measuring suspended particles.
- Conductivity Meter: Determines the water’s ability to conduct electricity, indicating ion concentration.
- Spectrophotometer: Analyzes the concentration of specific substances by measuring light absorption.
- Analytical Balance: Provides precise measurements of chemical reagents.
- Hot Air Oven: Used for drying and sterilization processes.
- Water Bath: Maintains samples at a constant temperature during testing.
- Distillation Unit: Purifies water samples for accurate testing.
- Magnetic Stirrer with Hot Plate: Mixes solutions uniformly during chemical analysis.
- Microbiological Testing Equipment
Ensures the detection and analysis of microbial contaminants:
- Bacteriological Incubator: Provides optimal conditions for microbial growth.
- Autoclave: Sterilizes equipment and media to prevent contamination.
- Laminar Air Flow Cabinet: Offers a sterile environment for microbiological work.
- Colony Counter: Counts the number of microbial colonies in a sample.
- Microscope: Allows for the observation of microorganisms.
- Filtration Assembly with Vacuum Pump: Concentrates microbes from water samples for analysis.
- Auxiliary Equipment
Supports various laboratory operations:
- Centrifuge: Separates components in a sample based on density.
- Refrigerator: Stores temperature-sensitive reagents and samples.
- Glassware: Includes beakers, flasks, pipettes, and measuring cylinders for handling and measuring liquids.
These equipment lists are indicative; specific requirements may vary based on the scope of testing and BIS guidelines.
