Industry Challenges

Thermostatic baths, circulators, and shakers must maintain long-term stability and repeatable performance while operating quietly and efficiently in temperature-sensitive environments.

Continuous-duty operation
Long runtime under constant load.
Low noise and vibration
Essential for maintaining a quiet laboratory environment.
Temperature and chemical resistance
Components must withstand exposure to heat, moisture, and vapours.

Compact integration
Fitting motors and gearboxes into sealed instrument housings.
Precision control
Ensuring repeatable motion profiles and consistent test conditions.

How Motion Technology Supports Laboratory Agitation and Circulation Systems

Rotalink’s gear motors enable smooth, efficient control of pumps, impellers, and agitation mechanisms.

Our miniature gearboxes provide stable torque, reduced speed, and precise motion control — ensuring dependable performance for temperature and mixing systems.

Our technology delivers:

High torque at low speed
For smooth fluid movement.
Low backlash gearing
For stable oscillation and shaking motion.
Sealed, durable housings
For moisture and chemical protection.
Energy-efficient operation
For extended continuous use.

Applications of Miniature Motors and Gearboxes in Baths, Circulators, and Shakers

Rotalink | Bath, Circulator & Shaker Actuation 2

Laboratory Baths (Water or Oil Baths)

Function: Maintain uniform temperature and solution mixing using gentle stirring or continuous agitation.
Gearbox Role: Drives impellers or paddles for controlled fluid motion.
Pump Actuation: n circulatory baths, gear motors move fluid through external or internal channels.
Requirements:
- Quiet operation to minimise laboratory noise.
- Continuous-duty rating for long runtime.
- Sealed housing for indirect chemical resistance.

Circulators (Thermostatic or Recirculating Units)

Function: Constant airflow, pressure accuracy, very low noise, compact design, long-term durability.
Gearbox Role: Precise airflow regulation, quiet operation, durability for thousands of hours, energy efficiency.
Integration: Patient comfort, compliance, and reliable nightly therapy.
Requirements
- High torque at low speed.
- Compact design for enclosed systems.
- Thermal stability and moisture sealing.

Shakers (Orbital, Rocking, or Reciprocating)

Function: Translate rotary motion into oscillating, circular, or tilting motion for sample mixing or agitation.
Gearbox Role: Converts motor rotation into controlled oscillation or reciprocation.
Performance Needs: Handles varying sample weights with consistent motion.
Requirements:
- Smooth motion with low backlash.
- Long life and minimal maintenance.
- Programmable movement profiles using stepper or servo gear motors.
