LABOPORT® Diaphragm Vacuum Pumps Collection

Perfect Match for Vacuum Desiccators

When it comes to creating optimal conditions for drying and preserving sensitive materials, diaphragm pumps from the LABOPORT® series are the perfect match for vacuum desiccators. If you have a desiccator with a volume of X liters, it is recommended to use a pump with a capacity greater than X L/min. This ensures that the pump can efficiently evacuate the air and moisture from the desiccator. Higher pumping capacity ⚙️ translates to faster evacuation, while using a pump with less capacity than the volume to be evacuated may result in inefficient performance.

Designed for 100% oil-free operation 🌱, these pumps guarantee contamination-free environments essential for applications in laboratories, pharmaceuticals, and material science. Proudly made in Germany with a Swiss core, they reflect high standards of quality and engineering.

With their compact and portable designs 👜, LABOPORT® pumps easily integrate into existing setups, providing reliable vacuum performance tailored to your specific needs. Explore how LABOPORT® pumps enhance the efficiency and effectiveness 🔧 of vacuum desiccators for superior material preservation.
