COLO.SCIENCE – MIXING & SHAKING EQUIPMENT / COMPACT ORBITAL SHAKERS
Why ORSHA21 is a practical compact orbital shaker for routine laboratory work
The ORSHA21 compact orbital shaker is designed for laboratories that need controlled shaking without occupying much bench space. Its 320 × 320 mm platform, 0–300 rpm speed range and 20 mm amplitude make it suitable for routine shaking, sample agitation, gentle mixing and preparation tasks using small to medium laboratory vessels.
ORSHA21 is positioned as a simple and reliable bench-top solution for users who do not need a large incubated shaker or a high-capacity multi-platform system. The PID LCD control, soft-touch buttons, timer settings and automatic operation functions make it practical for everyday use in education, quality control, research support and routine laboratory workflows.
Key features
- Compact orbital shaker for routine bench-top laboratory shaking.
- 0–300 rpm speed range with ±1 rpm rotation speed accuracy.
- 20 mm shaking amplitude for controlled round shaking motion.
- PID LCD control with soft-touch button input.
- Automatic direction change, automatic shutdown, quick start and quick stop.
Where it fits best
- Routine laboratory shaking and gentle sample agitation.
- Small and medium flask or beaker workflows.
- Education, training and demonstration laboratories.
- Quality-control labs requiring repeatable bench-top shaking.
- Users who need a compact shaker before moving to larger platform systems.
PRACTICAL USE & WORKFLOW
Why users choose ORSHA21
ORSHA21 is useful when a laboratory needs a straightforward shaker for everyday mixing tasks, without the size or complexity of a larger shaking incubator. Its compact footprint and simple control interface make it suitable for laboratories where multiple small devices must fit into limited bench space.
The automatic direction change function supports more consistent sample movement, while timer-controlled operation and automatic shutdown help users run repeatable procedures. Quick start and quick stop are useful for short shaking cycles and routine preparation steps.
COLO.Science & configuration support
COLO.Science supports shaker selection according to vessel type, vessel volume, platform load, fixing method, operating speed and laboratory workflow. This is especially useful when choosing between a compact shaker such as ORSHA21 and larger orbital shaker systems such as ORSHA344.
For ORSHA21, the key configuration points are vessel volume, vessel diameter, liquid working volume, bar fixing method, platform load and expected shaking speed. These should be confirmed before final quotation.
