1.I. Laboratory Applications

2.Chemical Experiments

·Rotary Evaporators: Used for rapid solvent evaporation (e.g., organic solvent recovery, sample concentration).

·Vacuum Filtration: Accelerates filtration processes (e.g., precipitate separation, filtration of bacterial cultures).

·Vacuum Drying: Enables low-temperature drying for heat-sensitive materials (e.g., biological samples, chemical reagents).

·Inert Gas Purging: Vacuum environments allow displacement with inert gases (e.g., argon, nitrogen) to prevent sample oxidation.

3.Biological Experiments

·DNA/RNA Extraction: Facilitates rapid nucleic acid isolation using vacuum suction methods.

·Cell Culture: For liquid extraction from culture plates or adjusting incubator pressure.

·Centrifugal Concentration: Speeds up solvent evaporation during centrifugation.

4.Physics and Analytical Experiments

·Vacuum System Setup: Provides初级vacuum support for equipment like mass spectrometers or spectrometers.

·Gas Experiments: Studies gas flow, pressure changes, or physical phenomena under vacuum (e.g., electric discharge experiments).

5.II. Industrial and Professional Applications

1.Medical and Pharmaceutical Fields

·Device Manufacturing: Vacuum sealing of syringes, vials, etc., to avoid contamination.

·Diagnostic Procedures: Blood sampling or preparation of vacuum blood collection tubes.

·Lyophilization: Dehydration of pharmaceuticals in small freeze-drying machines.

2.Electronics and Semiconductors

·Circuit Board Production: Vacuum adsorption for component fixation or pre-encapsulation processing.

·Leak Testing: Detects seal integrity of electronic components and devices.

3.Food and Packaging

·Vacuum Packaging: Extends food shelf life (e.g., household vacuum sealers).

·Degassing: Removes oxygen from food to prevent oxidation.

4.Environmental and Safety Testing

·Water Sampling: Extracts groundwater or sewage samples without external contamination.

·Gas Sampling: Collects volatile organic compounds (VOCs) or biogas from soil/water.

5.Research and Material Science

·Vacuum Coating: Supports small-scale sputtering or evaporation coating systems.

·Material Synthesis: Controls reaction pressure in processes like chemical vapor deposition (CVD).

6.Education and Teaching

·Physics Demonstrations: Illustrates effects of air pressure or vacuum (e.g., Magdeburg hemisphere experiment).

·Chemistry Classes: Simulates industrial vacuum conditions (e.g., reduced-pressure distillation).

6.III. Specialized Use Cases

·Automotive Repair: Evacuates air from brake systems to ensure hydraulic efficiency.

·DIY and Hobbyist Projects: Builds vacuum adsorption tools (e.g., phone holders, mini suction cups).

·Agriculture and Aquaculture: Extracts mud from fish ponds or samples water quality.

7.IV. Selection Guidelines

·Corrosion Resistance: Prioritize chemical-proof materials (e.g., PTFE-coated or stainless steel) for corrosive experiments.

·Pressure Control: Choose models with adjustable pressure or built-in manometers for precise experiments (e.g., rotary evaporation).

·Portability: Battery-powered or compact designs suit fieldwork or mobile scenarios.

The versatility and compact design of small vacuum pumps make them indispensable tools across laboratories, industries, and research fields, catering to diverse needs from basic teaching to professional production.
