MAJOR SCIENCE · WINPACT · WP-COS

Add orbital motion to your incubator workflow

The Winpact WP-COS is an orbital shaker designed for use inside a suitable CO2 incubator. It is not an incubator and does not provide its own temperature, humidity or CO2 control. Major Science specifies corrosion-resistant construction to help protect internal components in high-CO2, humid conditions.

A brushless motor drives a 20 mm orbit across the 300 x 300 mm platform. The separate 12-inch color touch controller provides speed adjustment and continuous, timed or programmable operation, allowing you to select the run style that fits your protocol.

Incubator-based mixing

Add a purpose-designed orbital shaker to a suitable host CO₂ incubator, instead of assuming an ordinary bench shaker is suitable.

Separate touch control

Use the 12-inch panel for continuous, timed or programmable operation. Agree controller placement and cable routing for the site.

Defined mixing format

A brushless motor, 20 mm orbit and 300 × 300 mm platform provide clear parameters for a fit and load review.

SI-910

Refrigerated, non-CO₂ format

25 mm orbit; 10–300 rpm; 4–60°C at 23–25°C ambient. No CO₂ or humidity control specified.

SI-960

Refrigerated CO₂ format

50 mm orbit; 10–180 rpm; 4–60°C at 23–25°C ambient. 0.1–20% CO₂; 50–95% RH; HEPA optional.

WP-COS · Current model

Shaker for an existing incubator

20 mm orbit; 1–300 rpm; 300 × 300 mm platform. Requires a suitable host incubator for environmental control.

Check the chamber before choosing the shaker

The base measures approximately 310 x 310 x 97 mm including the tray platform. Use these dimensions as the starting point for a fit check, then account for vessel height, holders, orbital movement, ventilation and cable routing. The published base dimensions are not a minimum incubator chamber specification.

Confirm the incubator shelf loading limit against the base mass of approximately 7.15 kg plus the planned load. The controller measures 320 x 102 x 246 mm and weighs approximately 4.65 kg. Controller placement, cable access and required clearances should be agreed for the installation.

Select speed and run mode at the touch panel

The 12-inch color touch panel supports continuous, timed and programmable modes. Shaking speed is adjustable from 1 to 300 rpm in 1 rpm steps, and the specification also lists a 0 rpm setting.

For protocols that depend on a particular timing range, sequence length or saved-program workflow, confirm those details before purchase. The public specification does not define program-step limits, stored recipe capacity or the full timer range.

Match vessel retention to your experiment

The 300 x 300 mm platform has a 316L top plate. Major Science lists strip springs, a 200 x 200 mm sticky pad, 300 x 300 mm dimpled and flat mats, and flask holders in nominal sizes from 50 to 2000 mL as accessories for this model.

Choose retention accessories around the actual vessel geometry, working load and intended speed. Holder size is not a claim about how many vessels fit on the platform or how much culture volume the shaker can process. Confirm the accessory arrangement rather than using photographs as a packing list.

Specify the complete configuration

The listed WP-COS configuration combines the orbital shaker, 12-inch color touch controller and flat-mat platform. A blue sticky pad is a different retention option, not the stated flat-mat configuration.

Confirm the supplied cable and its length, the final platform assembly and any additional vessel-retention accessories when defining the order. An incubator, glassware, blue sticky pad and pictured flask holders are not part of that stated configuration.

1 · Space and access

Start with the approximately 310 × 310 × 97 mm base envelope, then add your vessel height, retaining hardware, motion clearance and access.

2 · Shelf and load

Check the host shelf rating for the approximately 7.15 kg base plus the planned load. The shaker maximum load is 5.2 kg.

3 · Conditions and cable

Confirm temperature, humidity, CO₂ conditions, cable reach and routing. Published base size does not establish a universal incubator fit.

Alternative format

A different orbital format for a separately defined bench or chamber workflow. Review its lower published speed range and different load rating; it is not an integrated incubator or a like-for-like replacement.

Explore a separate liquid-transfer step. Tubing and flow requirements are selected independently; no mechanical, electrical or automated integration with this shaker is implied.
