We engineer our motors in-house, allowing them to provide longevity of the end devices. Thanks to our state-of-art engineering Thomas vacuum pumps and compressors are regarded as reliable and efficient components for life science research applications.
Vacuum concentrators use centrifugal force to concentrate or evaporate multiple samples, under vacuum, for further analysis. The process typically requires a chemical-resistant diaphragm vacuum pump or system with particular attention to your setup. Low volatility solvents and high gas flow at the operating pressure show a correct chosen vacuum level. Trapping solvent vapors using a refrigerated trap is recommended to prevent pump flooding and protect air quality. In smaller labs, one vacuum pump can run both a vacuum gel dryer and a vacuum concentrator. A chemical duty diaphragm vacuum pump can be used to serve these two devices by assembling a basic manifold with tubing and two in-line valves, despite the vacuum concentrator needing a deeper vacuum to evaporate solvents.
Nitrogen generators produce nitrogen from compressed air supplied by a dedicated air compressor. The compressor is mounted at the beginning of the system and passes compressed air through sets of filters to remove the impurities before entering into the generator. The filtrated air then passes through another filter that eliminates oxygen and carbon dioxide molecules resulting in high purity of hydrogen gas.
Microplate washers are designed to supply cleaning buffers and remove excess reaction substances in microplates used in diagnostic processes. Liquid pumps are used for transferring the cleaning agents and vacuum pumps for the removal of residue substances.
Aspiration is the process of removing fluids or gases via suction. A general lab aspiration setup consists of a sample that will be aspirated (in a bottle, spilled liquid, on a multi-well plate, etc.), a liquid trap, and a vacuum pump. Researchers commonly use aspiration setups to remove supernatants from different manufactured deep well plates after centrifugation to pick up spilled liquids on a bench.
Cell harvesting is the process of collecting animal or human blood or bone marrow cells. A cell harvester and a vacuum pump are the two critical components of equipment to accomplish this goal.
A vacuum concentrator uses centrifugal force with heat and vacuum to rapidly evaporate and condense solvents from biological and analytical samples. The concentrator and vacuum pump are the two Essential elements of lab equipment to accomplish this.
A desiccator is a round or square vessel, usually made of glass, plastic, or stainless steel used to equilibrate materials in a controlled atmosphere without moisture.
Vacuum filtration uses a pressure differential (atmosphere above filter paper and vacuum beneath) to drive a solution through a paper filter. The filtration flask is connected to a pump that generates the vacuum necessary for this procedure.
Lyophilization, also called freeze-drying, is a method of removing water, organic solvents, and/or acids from various materials through sublimation.
Pipettes are a lightweight, handheld devices ideal for precise, safe, and fatigue-free series pipetting in conjunction with standardized graduated pipettes. With the help of a miniature vacuum pump, individual tasks like slow or rapid aspiration, setting the liquid meniscus, or emptying the pipette can be conducted.
A rotary evaporator is a device used in laboratories where a liquid is evaporated by reducing the pressure and applying heat. At the same time, the samples are rotated in a vessel. A typical rotary evaporator setup requires a vacuum pump, a vacuum controller, and a chiller.
Solvent degassing implies removing a particulate matter and dissolved gases from solvents, as it can create false peaks or baseline instability. Most instrument manufacturers recommend filtration and degassing of solvents and samples before they are analyzed. The vacuum pump evacuates the gases and allows for reduced instrument downtime, extended column life, and optimized instrument performance.
Tissue culture is the technique or process of keeping tissue alive and growing in a culture medium. During the procedure, an aspiration pump may be needed to remove the medium from the culture vessel. A typical tissue culture aspiration setup consists of a liquid trap, vacuum pump, and pipette to remove the culture medium.
Vacuum concentrators offer a fast and convenient means to concentrate on clinical or research samples for analysis.
Dental laboratories are using special ovens for manufacturing ceramic prosthesis. These ovens use vacuum pumps to evacuate air or other gases from the melted ceramic in the burn chamber, and prevent the cavities.
