Laboratori

1. Protects the user (personnel)
   Prevents exposure to harmful biological agents (bacteria, viruses, aerosols).
2. Protects the sample/product
   Maintains a sterile working environment to avoid contamination.
3. Protects the environment
   Filters and prevents hazardous particles from being released into the lab.
4. Controls airflow
   Uses HEPA-filtered air to ensure clean, directional airflow inside the cabinet.

1. Separates chemical compounds
   Gas chromatography separates mixtures into individual components based on volatility.
2. Identifies compounds
   Mass spectrometry detects and identifies compounds by their unique mass spectra.
3. Quantifies substances
   Measures the concentration of specific compounds in a sample.
4. Analyzes complex mixtures
   Useful for analyzing environmental samples, food, pharmaceuticals, and forensic samples.
5. Detects trace-level compounds
   Highly sensitive—can detect very small amounts of chemicals.

1. Removes solvents efficiently
   Evaporates solvents from samples using reduced pressure (vacuum) and gentle heating.
2. Concentrates samples
   Increases the concentration of desired compounds by removing excess solvent.
3. Performs low-temperature evaporation
   Allows evaporation at lower temperatures, protecting heat-sensitive compounds.
4. Improves evaporation speed
   Rotation increases surface area, speeding up the evaporation process.
5. Solvent recovery
   Condenses and collects evaporated solvent for reuse.

1. Protects the user from hazardous fumes
   Removes toxic vapors, gases, and aerosols from the working area.
2. Improves laboratory safety
   Reduces exposure to dangerous chemicals during experiments.
3. Controls airflow and ventilation
   Draws contaminated air away from the user and expels it safely.
4. Prevents inhalation of harmful substances
   Ensures that chemical fumes do not enter the breathing zone.
5. Provides a controlled working environment
   Suitable for handling volatile, corrosive, or toxic substances.

Functions of Freezers

 -80°C Freezer (Ultra-Low Temperature Freezer)

1. Long-term sample storage
   Stores biological samples such as DNA, RNA, proteins, and microorganisms for extended periods.
2. Preserves sample integrity
   Extremely low temperature slows down enzymatic activity and degradation.
3. Prevents microbial growth
   Inhibits bacteria and fungi from growing.
4. Used for sensitive research materials
   Suitable for vaccines, cell cultures, and clinical samples.

1. Short- to medium-term storage
   Used for storing reagents, enzymes, and samples for shorter durations.
2. Maintains stability of materials
   Helps preserve chemicals and biological substances.
3. Prevents degradation
   Slows down chemical reactions and biological breakdown.
4. Common lab storage
   Widely used for everyday laboratory needs.

Functions of Chiller 

1. Controls and maintains temperature
   Keeps equipment or samples at a stable, low temperature during experiments.
2. Removes excess heat
   Absorbs and dissipates heat generated by instruments such as lasers, reactors, or analytical equipment.
3. Provides continuous cooling
   Circulates coolant (usually water or glycol mixture) to ensure consistent cooling performance.
4. Improves equipment performance
   Prevents overheating, ensuring instruments operate efficiently and accurately.
5. Enhances experiment stability
   Maintains constant conditions, which is critical for reproducible scientific results.
