Laboratory pumps

Laboratory pumping systems are used to transfer volumes of fluids and gases. Vacuum pumps are used in chemistry labs for filtration or decreasing the pressure in drying or evaporation and distillation processes. Syringe pumps and peristaltic pumps are frequently used to accurately transfer liquids, e.g. through a microfluidics system.

Wet gas vacuum pump Laboport SD N 860.3 FT.40.18 KNF-cover
Wet gas vacuum pump Laboport SD N 860.3 FT.40.18 KNF

Laboport SD N 860.3 FT.40.18 is a two-stage pump with an integrated “self-drying” system for automat (more)ic condensate drain. The “SD” series is widely used in laboratories, especially when the vapors are humid and a clean and ecological vacuum is required. Typical applications are: vacuum ovens (for drying chemicals, drying biological samples, heat treatments), autoclaves for sterilizing instruments, containers, filters and textiles. Thanks to the use of anti-corrosion materials, it is possible to vacuum even corrosive products. The heart of the pump is the diaphragm with differentiated structure in PTFE, optimized to guarantee high performance with reduced dimensions and at the same time, long life even in heavy applications. When the humid gases are sucked in, it can happen that condensation forms in the pump head: consequently the performance decreases, considerably increasing the emptying time. To eliminate condensation, the 'drying system' then opens a solenoid valve that allows ambient air to enter the heads. Once the condensation has been eliminated, the solenoid valve closes and the pump sucks from the stove in full capacity. Over time, condensation could form again and then the cycle is repeated. The time interval between one cycle and the next can be adjusted as desired, as well as the duration of the air injection. Technical features Flow rate (max.) 60 l / min Final vacuum (max.) 4 mbar (abs.) Pressure (max.) 1 bar (rel.) Fluid temperature allowed at 5-40°C FFPM valve material PTFE coated diaphragm material Pump head material PTFE Applications Rotary evaporation Centrifugal concentration Distillation Vacuum oven Qualitative characteristics Clean operation, 100% oil-free Corrosion resistant PTFE / FFPM flow path Ideal for extremely aggressive / corrosive gases and vapors Compact, silent and reliable The self-drying system removes condensation without altering the vacuum level Maintenance free Download the data sheet for further information and accessories.
