The UMH-KJMR-IV and UMH-KJMR-IVA Laboratory Tube Rotator Mixers
are designed for gentle 360° rotational mixing of blood, urine and other
laboratory liquid samples.
Both models use a rotating plate with a fixed
38° inclination angle to keep samples moving continuously
during mixing.
The UMH-KJMR-IV provides simple continuous operation, while the
UMH-KJMR-IVA adds digital speed adjustment, timer control and an LED display.
Key Features

360° Gentle Rotational Mixing
The rotating plate provides continuous
360° rotational motion.
A fixed 38° plate inclination helps maintain continuous
sample movement during rotation.
This mixing method is suitable for applications where samples need to remain
gently suspended without aggressive shaking.
Designed for Blood and Laboratory Samples
The rotator is suitable for mixing blood samples, urine samples and other
laboratory liquids that require gentle and continuous motion.
Typical applications include clinical laboratories, blood collection
laboratories, diagnostic laboratories and research facilities.
Interchangeable Tube Clips
The rotating plate supports interchangeable elastic tube clips for different
tube sizes.
Available clip configurations can accommodate common centrifuge tubes and
laboratory test tubes.
- 50 mL centrifuge tubes
- 15 mL centrifuge tubes
- 1.5 mL centrifuge tubes
- Test tubes with Ø8 mm diameter
- Test tubes with Ø9 mm diameter
- Test tubes with Ø12 mm diameter
- Test tubes with Ø13 mm diameter
- Test tubes with Ø16 mm diameter
The required clip or plate configuration should be confirmed before ordering
according to the tube size and quantity.
UMH-KJMR-IV Continuous Rotator Mixer
The UMH-KJMR-IV is the standard continuous-operation model.
Its rotation speed can be adjusted from
6 to 32 rpm.
The simple control configuration is suitable for laboratories requiring
continuous rotational mixing without programmable timing.
UMH-KJMR-IVA Digital Rotator Mixer
The UMH-KJMR-IVA adds digital speed and timer control
to the basic rotator platform.
The rotation speed can be adjusted from
5 to 35 rpm.
A digital timing range of 0–999 minutes allows timed
or continuous operation.
The backlit LED display shows operating speed, time and operating mode
for easier reading and adjustment.
