Labtron’s Diaphragm Vacuum Pump LDVP-A11 is specifically engineered for laboratory applications that demand clean, oil-free, and continuous vacuum performance. With a pumping speed of 20 L/min, its PTFE antiseptic pump and rubber diaphragm ensure high chemical resistance and long service life, making it ideal for sensitive operations like vacuum filtration, drying, and distillation without risk of sample contamination.
The oil-free design of the Diaphragm Vacuum Pump LDVP-A11 eliminates the need for routine oil changes and prevents backstreaming, which can contaminate samples or the work environment. This not only simplifies maintenance but also ensures clean vacuum conditions, crucial for accurate analytical results and safe handling of volatile chemicals.
Yes, our Diaphragm Vacuum Pump LDVP-A11 is designed for 24-hour continuous operation. This is made possible by its integrated automatic cooling exhaust system, which prevents overheating during prolonged use. This feature is particularly valuable in high-throughput laboratories or long-duration processes like vacuum drying or rotary evaporation.
Our Diaphragm Vacuum Pump LDVP-A11 offers a pressure-adjustable system, allowing users to fine-tune vacuum levels and gas flow according to specific application needs. This adjustability ensures optimal performance for tasks ranging from gentle solvent filtration to more demanding processes like vacuum distillation or SPE extraction.
Labtron’s Diaphragm Vacuum Pump LDVP-A11 features a friction-less membrane movement mechanism that reduces internal wear and energy consumption. Additionally, the pump head is constructed from corrosion-resistant materials like PTFE and nitrile rubber, ensuring long-term durability even in chemically aggressive environments. Its noise level remains under 50 dB, offering quiet, lab-friendly operation.
