Research institutions have extremely high requirements for the experimental environment and sample purity. Traditional oil-lubricated vacuum pumps generate oil mist during operation, posing a risk of contaminating samples and affecting experimental results. They also require regular oil changes and maintenance, affecting continuous experiments. Leynow oil-free vacuum pumps adopt an oil-free lubrication structure to prevent oil contamination from entering the vacuum system from the source, and have become the preferred configuration for multiple processes such as laboratory filtration, rotary evaporation, vacuum drying, freeze-drying, mass spectrometers, and electron microscopes.
Challenges Faced by the Industry
The requirements of scientific research experiments for vacuum systems are not just about "pulling a vacuum", but more importantly, cleanliness, stability, low noise, and repeatability. In practical applications, customers often encounter the following types of problems:
Risk of Oil Contamination of Samples
Oil-lubricated vacuum pumps generate oil mist during exhaust, which may contaminate samples, reagents, and the experimental environment, affecting the accuracy of experimental data.
Vacuum Degree Fluctuations Affect Experimental Results
Rotary evaporation, freeze-drying, and mass spectrometry analysis have high requirements for vacuum degree; fluctuations can lead to experimental result deviations or poor repeatability.
Noise and Continuous Operation Issues
The laboratory environment is sensitive to noise, and oil-lubricated pumps are noisy; during continuous experiments, pump body overheating or vacuum fluctuations can affect the experimental process.
High Maintenance Costs
Vacuum pump oil needs to be replaced regularly. Under working conditions containing solvent vapor, the oil is prone to emulsification and deterioration, and downtime for maintenance affects experimental progress.
Leynow Research Institution Solutions
Targeting the actual working conditions of research institutions, Leynow provides overall vacuum solutions centered on oil-free vacuum pumps, forming a complete service closed loop from equipment selection and installation and commissioning to post-maintenance.
Clean and Oil-free Vacuum Acquisition Method
Oil-free vacuum pumps adopt a self-lubricating structure, and the inner wall of the cylinder is specially treated. They do not generate oil mist or exhaust gas, preventing lubricating oil from entering the vacuum system, meeting the laboratory's requirements for sample and experimental environment cleanliness.
Selection Solutions Matched to Experimental Needs
Based on the experimental type, vacuum degree range, pumping volume requirements, and usage environment, professional engineers provide selection suggestions to avoid efficiency and lifespan issues caused by "using a large pump for a small job" or "overloading a small pump".
Guarantee of Stable and Low-noise Operation
For long-term continuous experiments and low noise requirements in laboratories, the heat dissipation and noise reduction structures are optimized to reduce pump body overheating and noise interference, maintain stable vacuum degree output, and ensure experimental repeatability.
Full-cycle Service and Parts Guarantee
Providing installation and commissioning, regular follow-up visits, and maintenance contract services. Repair parts are Leynow original genuine parts. All repair projects come with a 12-month warranty to reduce unplanned downtime.
