The vortex mixer works well with 50ml container. But only when the liquid in the container does not exceed 40 ml, there will be enough space in the container to create the vortex effect. The liquid in the container is too full to vortex, but it still has the effect of mixing Voltage: 100-240V Frequency : 50/60HZ Output voltage : 12 V Lab Quality Mix up to 50ml The machine can mix up to 50 milliliter (approx. 1.7 fluid ounces) of liquid volume at high 0-3000rpm adjustable speed. The lab vortex mixer works well with test tubes and centrifuge tubes as well as other liquids with containers 50ml or less. Capacity: up to 50mL (1.7 fl. oz) Motor Type: brushless motor Type of movement: Orbital Orbital Diameter: 4.5mm Speed: 3000 &0-3000 RPM Permissible relative humidity: 80% Permissible ambient temperature[℃]: 5-40 Multiplate Adaptive Modules One Machine equipped wuth 8 modules(VM501-VM508) VM501 apply for centrifuge tube/test tube; VM502 apply for lab flask/multi tubes VM503 apply for 12mm blood collection tube VM504 apply for 5ml/15ml centrifuge tube*12 VM505 apply for 50ml centrifuge tube*4; 5ml/15ml centrifuge tube *5 VM506 apply for 0.2ml centrifuge tube*96 / 96 well plate VM507 apply for cell culture plate VM508 apply for 0.5ml centrifuge tube *20 ; 1.5/2ml centrifuge tube *30 Vortex Mixer with Multifunction Knob Model & Display Model The VM500 series multi plate vortex mixer is the ideal vortex mixer for any laboratory. The unit's Touch and Continuous modes euiquited with multi modules and timing function make it easy to different experimental requirements. The small and compact design conserves bench space, yet the mixer is powerful enough to deliver robust vortex mixing at 3000 rpm Digital display available; Ultra-low body ,operation more stable Stepless speed regulation; Brushless motor with string power. With timing function Touch/ Continuous easy to switch With various fixtures,suitable for centrifugal tube, lab flask,blood tube,PCR plate cell culture plate and so on. You can mix what you want. Except for lab use, it's suitable for other daily use also,such as mix nail polishes, eyelash adhesives, paints, glues, tattoo ink, pigments and other tough liquids. 2100rpm Vortex Mixer Pink Vortex Mixer Blue Mini Vortex Mixer Multifunction Vortex Mixer Digital Multifunction Vortex Mixer Buying Options Add to Cart Add to Cart Buying Options Buying Options Customer Reviews 4.3 out of 5 stars 162 4.3 out of 5 stars 162 4.0 out of 5 stars 253 — — Price $39.99 $ 39 . 99 $39.99 $ 39 . 99 $59.99 $ 59 . 99 — — Model VM-210 VM-300P VM-300 VM-500S VM-500pro Control method Knob speed regulation Constant speed Constant speed Knob speed adjustment PWM speed adjustment Shaking speed 2100RPM 3000RPM 3000RPM Touch:0-3000RPM; Run: 200-3000RPM Touch:0-3000RPM; Run: 100-3000RPM Max. capacity 50ML 50ML 50ML 50ML*4/ 15ML*9 /5-10ML*12 / 2ML*24 50ML*4/ 15ML*9 /5-10ML*12 / 2ML*24 Timing / / / 1-99min/1-59sec 1-99min/1-59sec Operating model Touch Touch Touch Touch/Run Touch/Run Display / / / / LCD Shaking Orbit 4.5mm(circle) 4.5mm(circle) 4.5mm(circle) 4.5mm(circle) 4.5mm(circle) Motor Brushless Motor Brushless Motor Brushless Motor Brushless Motor Brushless Motor
