The Variable speed Vortex Mixer (MX-S) is a versatile benchtop vortex mixer with adjustable speed control (0-3000 rpm), analog scale speed display, and touch/continuous operation modes, designed for optimal mixing of blood collection tubes, reagents, and biological samples in clinical diagnostic and research laboratories . With variable speed control, operators can select the appropriate mixing intensity for different sample types—gentle speeds (0-500 rpm) for resuspension of cell pellets and coagulation tubes to prevent platelet activation, moderate speeds (500-1500 rpm) for routine reagent mixing, and high speeds (1500-3000 rpm) for rapid mixing of buffers and viscous solutions .
Key features include dual operating modes—touch activation for quick mixing of individual tubes and continuous operation for extended mixing of bulk reagents or multiple samples, variable speed control knob for precise adjustment of mixing intensity (0-3000 rpm) with analog scale display for visual confirmation, and optional accessories including multi-tube head for 0.2 mL PCR strips and flat rubber pad for larger vessels (up to 50 mL conical tubes, small flasks) .
For the clinical laboratory scientist and phlebotomist, the Variable speed Vortex Mixer (MX-S) ensures optimal mixing of blood collection tubes after venipuncture with speed selection appropriate for different tube types—gentle speeds for light blue top coagulation tubes (PT/PTT) to prevent platelet activation, and higher speeds for lavender top EDTA tubes (CBC) and serum separator tubes to ensure thorough mixing of anticoagulants and clot activators . For the molecular biologist, the MX-S facilitates resuspension of nucleic acid pellets, mixing of PCR reaction components, and homogenization of buffers for diagnostic assays .
Universal voltage (100-240V, 50/60Hz) enables use in laboratories worldwide without voltage conversion, while the compact footprint (127 × 130 × 160 mm) and lightweight design (2.0 kg) allow easy benchtop placement . Rubber suction feet prevent "walking" during high-speed operation, and low-noise operation ensures a comfortable working environment .
For the patient undergoing coagulation monitoring (warfarin, heparin), complete blood count (CBC), molecular diagnostic testing (COVID-19, influenza, hepatitis), or routine chemistry panels, the Variable speed Vortex Mixer (MX-S) variable-speed, optimized mixing ensures accurate test results that guide appropriate treatment decisions—preventing false-negative or false-positive results due to improper sample mixing .
