• For purchasers from molecular biology, biochemistry, clinical research and environmental testing labs, LVM-S variable speed vortex mixer supports mixing from gentle low speed to high speed. One single unit meets diverse scientific pretreatment demands and cuts the cost of purchasing multiple instruments.
• The 2.0kg unit equipped with steel vacuum suction base firmly adheres to the bench under all speeds from 0–3000rpm. It avoids displacement and vibration during long-time stirring of water samples, biological reagents and viscous extracts, ideal for daily batch sample processing in university research labs and third-party testing institutes.
• Dual operation modes fit diversified lab workflows: touch mode for rapid detection of tiny single tube samples (start by pressing, stop by releasing); continuous mode for batch processing of environmental specimens, macromolecule raw materials and high-viscosity extracts with non-stop long-hour stirring, matching multi-process parallel lab stations.
• Built-in electronic constant speed system maintains set rotation speed despite changes of sample volume and viscosity. The scale speed dial allows intuitive adjustment of mixing intensity, meeting the repeatability requirements for academic papers, clinical tests and official environmental test reports.
• Robust aluminum-cast housing with IP20 dust-proof structure prevents lab dust from entering internal components. The shaded pole motor requires no carbon brush replacement, suitable for year-round open teaching labs and commercial testing workshops to lower long-term maintenance cost.
• Universal 100–120V/200–240V wide voltage design with optional US/EU/UK/AU power plugs. When reselling overseas to molecular biology labs, environmental monitoring stations and small biochemical factories, it can work directly in all lab and production environments. Stable working range: 5–40℃, relative humidity ≤80%RH, no extra temperature control equipment needed for standard indoor labs.
• Standard mixing head included as factory default fits all test tubes and small vials within 30mm diameter. No extra adaptors are required for regular experiments such as molecular assays, water quality tests and biochemical analysis.

• If your lab processes samples of various viscosities, requiring gentle low-speed mixing for micro biological samples and high-speed stirring for viscous environmental water and biochemical extracts:
  LVM-S features 0–3000rpm stepless adjustable speed with a scale dial. One single instrument meets all mixing intensity demands, suitable for molecular biology, clinical research and environmental testing labs worldwide.
