Multi-Plate Microplate Shaker

What is the Multi-Plate Microplate Shaker?

A multi-plate microplate shaker holds two to four plates or deep-well blocks at once. It is chosen for high-throughput assay work where several plates must be mixed together in one single run.

Overview

The multi-plate shaker enlarges the platform to accept two to four microplates or deep-well blocks, so several samples are mixed in one run instead of one at a time. Speeds run 100 to 1200 rpm with a 2 to 3 mm orbit, and load ratings are low but must be distributed evenly. Clips or mats hold each plate, and the platform is sized to keep all plates moving consistently. Closed-loop control holds speed under the extra load, and timers or pulse modes run the assay steps. A wider platform increases vibration, so the base should be firm and level. It suits high-throughput ELISA, screening and sample preparation laboratories that process many plates per day.

How does it work?

A microplate shaker moves a small platform at high frequency with a short orbit, typically 1.5 to 3 mm, so each well is agitated without splashing liquid out of the small volume. A brushless motor turns an eccentric bearing, and the platform is held by plate clips or a rubber mat so plates and deep-well blocks stay in place. Speed is set from about 100 to 1500 rpm and held by closed-loop control, and timers or short-run buttons provide the pulses used in assay protocols. The small orbit and high frequency create vigorous mixing at low amplitude, which is effective for resuspending pellets and mixing reagents in wells. Some models accept two or four plates at once, and platforms may be interchangeable for tubes or microtubes.

What are the key features?

• Platform for two to four plates or blocks
• Speed 100 to 1200 rpm with 2 to 3 mm orbit
• Clips or mats for each plate
• Even load distribution for consistent mixing
• Closed-loop speed control under load
• Timer or pulse modes for assay steps

What are the technical specifications?

A typical multi-plate microplate shaker configuration offers plate capacity of 2–4 plates, speed range of 100–1200 rpm, orbit diameter of 2–3 mm, speed accuracy of ±5 rpm, timer range of 1 s to 99 min and pulse mode of Optional. 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 Multi-Plate Microplate Shaker is used in high-throughput ELISA, screening assay mixing, batch sample preparation and deep-well block mixing. Across the wider Microplate Shakers class, laboratories also deploy it for ELISA plate mixing and washing, cell-based assay mixing and immunoassay 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 shaker on a level surface close to the reader or washer so plates are not carried far, and ensure plates are fully seated in the clips before starting. Do not exceed the speed rating for the plates in use, since very high speeds can splash contents or loosen seals on covered plates. Balance the platform when more than one plate is loaded. Clean spills and spills of reagents promptly, since salts and proteins corrode the platform and clips. Check clips, mats and bearings on schedule, and keep covers or seals in good condition to prevent cross-contamination between wells.

How do I select the right Multi-Plate Microplate Shaker?

Select the multi-plate shaker when several plates must be mixed in the same run, as in high-throughput ELISA and screening. Single-plate units suffice for low volumes. In the RFQ, specify plate count and type, speed range, orbit, holding method and noise limits.

How does it compare with other Microplate Shakers variants?

Choose a microplate shaker when plates, deep-well blocks or strip wells must be mixed quickly in small volumes, as in ELISA, immunoassays and cell assays. Set the speed range from the task, using moderate speeds for gentle mixing and higher speeds for resuspension. Match the platform to the plate type and count, checking that clips or mats hold plates securely at high speed. Decide between single-plate and multi-plate platforms, and whether a timer, pulse mode or program storage is needed. Confirm the orbit suits the well volume, since too large an orbit splashes small volumes, and check noise, footprint and power supply before ordering.
