Vacuum Aspiration System LVAS-A12

Labtron supplies advanced models of vacuum aspiration system LVAS-A12. The liquid-level sensor is an advanced safety feature designed to prevent overflow in the collection bottle. It detects the rising fluid level and triggers an automatic shut-off when the maximum limit is reached. This prevents liquid from being drawn into the vacuum pump or filter, protecting internal components and maintaining system performance. The sensor can be based on float switches, conductivity, or optical detection, depending on the model. It enhances user convenience by eliminating the need for constant monitoring and reduces the risk of biohazard exposure or contamination due to accidental overfill.

Labtron’s high-quality vacuum aspiration systems LVAS-A12 use chemically resistant and autoclavable materials such as borosilicate glass, PTFE, polypropylene (PP), and silicone. These materials are chosen for their durability and compatibility with common lab reagents, including bleach, ethanol, and disinfectants. The collection bottles are often made of thick-walled PP or glass to withstand pressure and harsh chemicals. Suction tubes and pipette adapters are also resistant to corrosion and thermal stress. This ensures that the system can be cleaned, disinfected, or autoclaved without degradation, making it ideal for sterile and biosafety-level applications.

Vacuum pressure is usually controlled by a manual or digital regulator, allowing users to adjust suction strength based on the viscosity or volume of the liquid being aspirated. Proper vacuum control is crucial to avoid splashing, foaming, or disruption of delicate cell layers in tissue cultures. Some systems include fine-tune dials or programmable vacuum levels for precise control. Low vacuum is ideal for gentle aspiration, while higher vacuum settings are used for rapid removal of large volumes. Accurate pressure regulation improves workflow safety, liquid handling precision, and equipment longevity.

Labtron’s vacuum aspiration system LVAS-A12 is a laboratory device designed to safely and efficiently remove supernatants, cell culture media, or other liquids from tubes, plates, and flasks using vacuum pressure. It works by creating negative pressure in a collection vessel, allowing liquid to be aspirated through a pipette or suction tip. The vacuum source can be built-in or external and is often adjustable for different liquid viscosities. These systems are widely used in biosafety cabinets, tissue culture labs, and molecular biology workflows. Advanced models include features like footswitch operation, liquid-level sensors, and anti-overflow protection. They provide fast, contamination-free liquid handling in various applications.

Vacuum aspiration systems LVAS-A12 are commonly used for removal of supernatants, waste liquids, and spent culture media in cell culture, microbiology, molecular biology, and clinical diagnostics. They are particularly useful during DNA/RNA extraction, immunoassays, ELISA washing, and other workflows requiring precise liquid removal. In microbiological labs, they help in safely discarding biohazardous fluids. Their role in maintaining aseptic conditions and reducing manual pipetting errors makes them indispensable for workflows requiring sterility, speed, and safety. Their closed waste system minimizes exposure and maintains lab hygiene.
