ORSHA75 · ORSHA125 Orbital Shaker-Incubator · Compact Benchtop · Exchangeable Platforms
The ORSHA75 orbital shaker-incubator and its larger sister ORSHA125 shake and incubate in one compact benchtop unit. A brushless DC motor drives the platform on a 20 mm orbit, and the chamber is held from 5 °C above room temperature up to 60 °C. ORSHA75 (PRO4550) has a 230 × 230 mm platform and runs at 50–300 rpm; ORSHA125 (PRO4559) has a 350 × 350 mm platform, 50–250 rpm and carries up to 10 kg.
ORSHA75 and ORSHA125 models and order codes
| Model | Order code | Platform size | Speed | Load | Exterior W × D × H | Power |
|---|---|---|---|---|---|---|
| ORSHA75 | PRO4550 | 230 × 230 mm | 50–300 rpm | 4.0 kg | 320 × 421 × 338 mm | 350 W |
| ORSHA125 | PRO4559 | 350 × 350 mm | 50–250 rpm | 10.0 kg | 632 × 502 × 512 mm | 600 W |
Both models heat from RT+5 °C to 60 °C with a 20 mm orbit and a brushless DC motor. The main unit is supplied without a platform: choose one or more platforms from the table below.
Compact orbital shaker-incubator for flasks, tubes and plates
Exchangeable platforms turn the same unit into a flask shaker, a tube incubator, a microplate incubator or a Petri dish incubator. The LCD shows the time, temperature and speed, and all three are set with a few keys. Heating and shaking stop as soon as the transparent lid is opened, and after a power cut the run continues by itself.
Key features
- Temperature control RT+5 °C to 60 °C, accuracy and uniformity ≤ ±0.5 °C at 37 °C
- Orbital shaking, 20 mm; ORSHA75 50–300 rpm, ORSHA125 50–250 rpm
- Direct brushless DC motor for gentle, reliable shaking
- LCD with time, temperature and speed; timer 1 min to 99 h 59 min or continuous
- Shaking and heating stop when the lid is opened
- Automatic restart after a power failure; over-heating protection
- Built-in temperature calibration
- Exchangeable platforms: 7 for ORSHA75, 4 for ORSHA125
Suitable for
- Shake-flask cultures of bacteria and yeast
- ELISA and deep-well plates incubated with shaking
- 15 ml and 50 ml tubes in clamp platforms
- Small laboratories and teaching, where one unit replaces a shaker and an incubator
Exchangeable platforms and order codes
The main unit is supplied without a platform. Choose the platform by the vessels you use; you can order several and change them in a minute. The spring holder is the most flexible choice for mixed flask and bottle sizes.

Installation and care
Place the unit on a firm, level bench that does not vibrate, with free space around it for ventilation, and connect it to an earthed 220 V socket. Spread the vessels evenly over the platform and stay within the load limit. Wipe the chamber with a neutral detergent; do not use solvents on the acrylic lid.
Standard delivery and options
- ORSHA75 or ORSHA125 orbital shaker-incubator, main unit.
- Platform: ordered separately (see the platform table).
- Option: additional platforms for other vessels.
The configuration for a specific order is the one confirmed in the COLO.Science quotation.
