An orbital shaker or vortex mixer agitates liquid samples in tubes and small vessels so contents blend quickly and evenly. This category covers benchtop vortex mixers and the mini orbital shaker style used for tube mixing in labs, test benches and quality control stations. Buyers are mostly trade and industrial labs, calibration and testing departments, and technical teams that need fast, repeatable mixing of small volumes.
Compel carries a focused range here, not a wide one. It centres on mini vortex mixers: the VM-300 family with models from 2000rpm up to 3000rpm, and the VX-4 touch-start orbital unit. Both handle up to 50ml. Each listing gives speed, amplitude or orbital diameter, and capacity, so you can check the numbers against your method before ordering. UK plug options are available on the listings, which saves hunting for an adapter.

Fixed speed or variable speed vortex mixer
Start with how much control your method needs. The VM-200 runs at a constant 2000rpm and the VM-300 at a constant 3000rpm. The VM-300S has a stepless knob covering 0 to 3000rpm.
Fixed-speed units suit routine tasks where every sample gets the same treatment. A variable unit helps when you handle both viscous and thin liquids, or need a gentler start to avoid splashing. The VX-4 is fixed at 3000RPM, so it fits repeat jobs rather than speed-sensitive work.
- VM-200: 2000rpm, constant speed, 6W
- VM-300: 3000rpm, constant speed, 12W
- VM-300S: 0 to 3000rpm, stepless knob, 12W
- VX-4: 3000RPM fixed, touch start
Circular oscillation or orbital movement
The two product types move differently. The VM-300 family uses circular oscillation with 4.5mm amplitude. The VX-4 uses orbital movement with a 20mm orbital diameter.
A larger orbital diameter moves the sample through a wider path, which can mix a full tube faster. The VX-4 lists 5 seconds for a full 50mL container. Check your own method for the mixing result you need before choosing.
Capacity and vessel size
Both models list a maximum capacity of 50ml, so they suit small tubes and vials, not flasks or large bottles. If your work needs bulk volumes, long shaking runs or several vessels at once, a benchtop platform shaker or roller mixer is a different tool class, and these units won't replace it.
Match the vessel to the listed maximum and leave headroom in the tube so liquid doesn't climb the wall at 3000rpm.
Plug type and power
Plug options differ by listing. Some versions ship with an EU or US plug and need a UK adapter. Choose the UK plug option where it's offered. Power ratings are low: 6W for the VM-200 and 12W for the VM-300 and VM-300S. For any compliance or safety marking your site requires, check the listing datasheet.
Buying guide
Choosing Shakers & Vortex Mixers
- How do I choose between a vortex mixer and an orbital shaker for tube mixing?
- Check the movement and the capacity. The VM-300 family gives circular oscillation at 4.5mm amplitude. The VX-4 gives orbital movement with a 20mm orbital diameter. Both top out at 50ml, so for larger vessels you need a different class of lab shaker.
- What speed does a benchtop shaker like this run at?
- The VM-200 runs at 2000rpm. The VM-300 and the VX-4 run at 3000rpm, fixed. The VM-300S is the one with variable control, stepless from 0 to 3000rpm by knob. Pick the VM-300S if your samples need gentler mixing.
- What is the maximum volume I can mix on a mini vortex mixer?
- The listed maximum capacity is 50ml on both the VM-300 and the VX-4. The VX-4 lists a 5 second mix time for a full 50mL container. Don't fill tubes to the brim; leave air space so the sample mixes instead of spilling.
- Will these mixers work with a UK mains socket?
- Yes, if you choose the UK plug option on the listing. Some versions ship with an EU or US plug and need a UK adapter. Select the UK plug at order so you don't need to source one.
- Can a vortex mixer replace a rocker shaker or roller mixer?
- No. A vortex mixer agitates small tubes quickly in short bursts. A rocker shaker or tube rotator gives slow, continuous movement over long periods. This range covers mini vortex and orbital tube mixers, so check your method before swapping one type for another.
- What's a common mistake when buying a lab shaker for a test bench?
- Buyers often pick a fixed-speed unit when their method needs speed control. The VM-200, VM-300 and VX-4 run at one set speed. Only the VM-300S offers the stepless 0 to 3000rpm knob.
