Adjustable-Tilt Rocking Shaker

What is the Adjustable-Tilt Rocking Shaker?

An adjustable-tilt rocking shaker lets the user change the tilt angle to suit different tasks. It is chosen when one unit must handle gentle membrane work and stronger mixing of larger volumes.

Overview

This rocker adds an adjustable tilt mechanism, so the angle can be set from about 3 to 15 degrees, either continuously or in steps. A gentle 3 to 5 degrees keeps membranes and gels wet without washing them off, while 10 to 15 degrees moves solution further for mixing larger volumes or thicker samples. Speed remains separately adjustable from 5 to 80 tilts per minute. Platforms of 250 to 400 mm carry 2 to 8 kg, and rubber mats or clips hold trays, frames and boxes. Digital controllers may store tilt and speed settings. The mechanism uses a movable link or offset pivot, and the angle should be checked after each change. It suits multi-method laboratories and protocol development where tilt affects the result.

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?

• Adjustable tilt from about 3 to 15 degrees
• Independent speed from 5 to 80 tilts per minute
• Platform of 250 to 400 mm, load 2 to 8 kg
• Continuous or stepped tilt adjustment
• Rubber mats or clips to secure items
• Stored tilt and speed settings on digital models

What are the technical specifications?

A typical adjustable-tilt rocking shaker configuration offers platform size of 250×250 to 400×400 mm, tilt angle of 3–15 degrees, adjustable, speed range of 5–80 tilts/min, load rating of 2–8 kg, tilt adjustment of Continuous or stepped and drive type of Motor with adjustable link. 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 Adjustable-Tilt Rocking Shaker is used in method development comparing tilt angles, membrane and gel work with variable flow, mixing larger volumes gently and multi-method general laboratories. 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 Adjustable-Tilt Rocking Shaker?

Select the adjustable-tilt rocker when one unit must cover gentle membranes and stronger mixing, or during protocol development where tilt matters. Fixed-angle models are simpler for a single method. In the RFQ, specify tilt range, speed range, platform size and load.

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.
