Large-Capacity Reciprocating Shaker

What is the Large-Capacity Reciprocating Shaker?

A large-capacity reciprocating shaker provides a wide platform for many trays, racks or vessels in one run. It is chosen when the working area rather than the load mass limits the throughput of the laboratory.

Overview

The large-capacity reciprocal shaker emphasizes working area, with platforms of 700 to 1200 mm that hold many trays, sample racks or large vessels. Load ratings of 20 to 50 kg and strokes of 20 to 50 mm at 20 to 200 strokes per minute suit bulky loads. A reinforced frame and strong linear guides keep the wide platform moving straight, and a counterweight or opposed platform limits vibration. Soft start and closed-loop speed control protect the drive and keep results consistent. Trays can be arranged so several methods or sample batches share the platform. It suits soil and waste extraction, large staining runs and industrial washing where many items must be agitated together in one batch.

How does it work?

A reciprocal shaker converts rotary motor motion into linear motion with a crank and slider or an eccentric link, so the platform moves back and forth along one axis. Stroke length is set by the crank radius and typically ranges from 10 to 50 mm, while speed is set in strokes per minute from about 20 to 300. The back-and-forth movement creates shear at the liquid surface and along the vessel wall, which helps with washing, extraction and mixing of viscous samples where orbital motion alone is too gentle. A guide rail or linear bearing keeps the platform straight, and a counterweight or dual-opposed platform reduces vibration. Closed-loop control holds speed against load, timers run the cycle, and clamps or trays secure vessels so they do not slide with the motion.

What are the key features?

• Wide platform of 700 to 1200 mm
• Load rating of 20 to 50 kg
• Strokes of 20 to 50 mm at 20 to 200 per minute
• Reinforced frame with strong linear guides
• Counterweight or opposed platform to reduce vibration
• Soft start and closed-loop speed control

What are the technical specifications?

A typical large-capacity reciprocating shaker configuration offers platform size of 700×700 to 1200×1200 mm, stroke length of 20–50 mm, speed range of 20–200 strokes/min, load rating of 20–50 kg, trays supported of 2–6 and duty cycle of Continuous. 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-Capacity Reciprocating Shaker is used in soil and waste extraction, large staining and washing runs, industrial batch agitation and high-throughput sample preparation. Across the wider Reciprocal Shakers class, laboratories also deploy it for washing and rinsing of samples, liquid-liquid and solid-liquid extraction and staining and destaining procedures.

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.

Clamp or tray every vessel so it cannot slide with the reciprocating motion, and load the platform symmetrically to reduce vibration. Place the unit on a level, rigid surface with clearance for the moving platform, since reciprocal action can transmit vibration to the bench. Stay within the load rating at the working stroke and speed, and use a soft start or lower speed when vessels are full. Clean spills promptly to protect the rails and clamps. Lubricate or inspect the linear bearings and guides on schedule, check belts and fasteners for wear, and replace worn clamps that no longer hold vessels firmly.

How do I select the right Large-Capacity Reciprocating Shaker?

Select the large-capacity reciprocal shaker when the platform area limits throughput, such as many trays or racks at once. Heavy small loads are better served by a heavy-duty model. In the RFQ, specify platform size, load mass, stroke, speed and tray configuration.

How does it compare with other Reciprocal Shakers variants?

Choose a reciprocal shaker when linear shear is wanted rather than swirling, as in washing, extraction, staining and some homogenization steps. Set the stroke length from the vessel and the shear needed, since longer strokes move the liquid more but can splash, and set the speed from the method. Match the platform and clamps to the vessels, and the load rating to the total mass at the chosen speed. Decide between a single and an opposed dual platform, where the second platform balances the first and reduces vibration. Confirm the duty cycle for long runs, and specify the timer, soft start and power supply.
