Large-Platform Rocking Shaker

What is the Large-Platform Rocking Shaker?

A large-platform rocking shaker provides a wide tilting surface for big trays, multiple blots and bulk staining. It is chosen when several membranes or large gels must be processed together in a single staining run.

Overview

The large-platform rocker expands the tilting surface to 400 to 600 mm, so several blotting boxes, large gel frames or trays can be processed in one run. Load ratings of 3 to 10 kg and tilts of 3 to 12 degrees keep large items moving gently, and speeds run 5 to 70 tilts per minute. A reinforced pivot and stronger cam or belt handle the wide platform and heavier loads, and rubber mats hold trays in place. Some models offer adjustable tilt and digital timing. Because the platform is wide, liquid flow must be even across the surface, so the pivot is centred and the platform is stiff. It suits core facilities and laboratories that stain many membranes or large gels at once.

How does it work?

A rocking shaker pivots the platform about a central axis, so one end rises while the other falls, and the motion reverses each cycle. The drive is a motor turning a cam or crank that lifts the platform on alternating sides, and the tilt angle, usually 3 to 15 degrees, sets how far liquid flows each way. Because the movement is slow and symmetrical, shear is low and liquid spreads evenly over membranes, gels and slides without foaming or splashing. Speed is set in tilts per minute, from about 5 to 80, and rubber mats or dimpled platforms keep items from sliding. The gentle action suits fragile membranes and antibody incubations, and the open platform allows trays, gel frames and boxes to be placed directly. Timers and, on some models, programmable tilt and speed improve reproducibility.

What are the key features?

• Wide platform of 400 to 600 mm
• Load rating of 3 to 10 kg
• Tilt of 3 to 12 degrees
• Speed 5 to 70 tilts per minute
• Reinforced pivot and stronger cam or belt
• Rubber mats and optional adjustable tilt

What are the technical specifications?

A typical large-platform rocking shaker configuration offers platform size of 400×400 to 600×600 mm, tilt angle of 3–12 degrees, speed range of 5–70 tilts/min, load rating of 3–10 kg, drive type of Motor with reinforced cam and mat of Rubber, non-slip. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Large-Platform Rocking Shaker is used in bulk membrane staining, large gel processing, multiple blotting boxes at once and core facility staining workflows. Across the wider Rocking Shakers class, laboratories also deploy it for gel staining and destaining, western and Southern blotting and antibody and probe incubation.

Which standards and certifications apply?

Relevant standards and methods include IEC 61010-1, IEC 61010-2-051 and ISO 9001. Certification candidates for this model are CE, ISO 9001 manufacturing and RoHS; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Place the unit on a level, stable surface with clearance for the tilting platform, and use the rubber mat or clips so membranes, gels and boxes do not slide. Load items evenly around the axis so the drive is not strained, and stay within the load rating. For blotting and antibody work, use enough solution to keep the membrane wet but not so much that it floats off. Clean spills promptly and rinse trays to prevent residue that could contaminate later experiments. Check the pivot, cam and belt for wear on schedule, and confirm that the materials suit the solutions and temperatures used, especially in cold rooms.

How do I select the right Large-Platform Rocking Shaker?

Select the large-platform rocker when several membranes, large gels or trays must be rocked together and standard platforms are too small. Smaller units suffice for single blots. In the RFQ, specify platform size, load, tilt range, speed and whether adjustable tilt is needed.

How does it compare with other Rocking Shakers variants?

Choose a rocking shaker when gentle, low-shear movement is needed, as for gel staining, membrane washing, blotting and antibody incubation, where orbital or reciprocal motion could damage the substrate or cause foaming. Set the tilt angle from the task, using 3 to 8 degrees for membranes and slides and 8 to 15 degrees for mixing larger volumes. Match the platform size and mat to the trays, frames or boxes you will place on it, and confirm the load rating. Decide whether a fixed or adjustable tilt is needed, and whether a timer, digital control or dual platform improves your workflow. Confirm that the unit suits the temperature, such as a cold room, where it will be used.
