Orbital Microplate Shaker for ELISA Incubation

What is the Orbital Microplate Shaker for ELISA Incubation?

An orbital microplate shaker moves 96-well plates in a small circular path at 100 to 1,500 revolutions per minute to mix reagents during ELISA incubations. It is the standard benchtop shaker for immunoassay laboratories that need consistent, low-splash mixing at room temperature.

Overview

This variant uses a brushless motor driving an eccentric mechanism with a 2 to 3 millimeter orbit, providing circular motion in the horizontal plane. The platform carries one to four 96-well plates with spring clamps or a non-slip mat, and a timer supports continuous or timed operation up to 99 hours. Speed is adjustable in steps of 10 to 50 revolutions per minute and is held within plus or minus 2 percent by electronic feedback. The orbit and speed range prevent splashing in standard 96-well plates filled to 200 microliters per well. Some units include a soft-start to avoid sudden acceleration and an overload alarm. There is no heating, so assays run at ambient temperature, and humidity covers or sealing films are used to limit evaporation. The design is robust, quiet and low maintenance.

How does it work?

A microplate shaker converts motor rotation into a small, controlled plate movement. In orbital designs, an eccentric cam or drive pin moves a platform in a circular path with an orbit diameter of about 1 to 4 millimeters, and speeds of 100 to 1,500 revolutions per minute. Linear shakers move the plate back and forth, and double-orbital shakers combine two circular motions for vigorous mixing in small wells. The amplitude is deliberately small so liquid swirls within each well without spilling, and surface tension limits splashing in high-density plates. Microplate clamps or non-slip platforms hold plates of different heights. Heating versions add a block or forced-air system for temperature control, and brushless motors with speed feedback provide consistent rotation for long incubations.

What are the key features?

• 2 to 3 millimeter orbit keeps 200 microliter wells free of splashing
• Brushless motor with electronic speed feedback within plus or minus 2 percent
• Holds one to four 96-well plates with clamps or non-slip mat
• Timer for continuous or timed operation up to 99 hours
• Soft-start and overload alarm protect plates and motor
• Quiet, low-maintenance operation suited to benchtop and cold room use

What are the technical specifications?

A typical orbital microplate shaker for elisa incubation configuration offers motion type of Orbital, orbit diameter of 2–3 mm, speed range of 100–1,500 rpm, speed accuracy of ±2%, timer of 1 min–99 h, continuous and plate capacity of 1–4 plates (96-well). 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 Orbital Microplate Shaker for ELISA Incubation is used in ELISA antibody and conjugate incubations, serology immunoassays, protein coating and blocking steps, colorimetric reagent mixing and bacterial adhesion assays. Across the wider Microplate Shakers class, laboratories also deploy it for ELISA incubation mixing, bead-based immunoassay suspension and cell suspension culture in plates.

Which standards and certifications apply?

Relevant standards and methods include ANSI/SLAS 1-2004 to 4-2004, IEC 61010-1, IEC 61010-2-051, IEC 61326-1 and ISO 13485 (IVD workflows). 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, stable surface and secure plates with clamps to avoid walking at high speed. Seal plates with adhesive film or lids to prevent evaporation and cross-contamination during long incubations. Check speed accuracy with a tachometer and, for thermoshakers, temperature accuracy with a calibrated probe during qualification and periodically thereafter. Clean spills immediately with compatible disinfectants and avoid liquids entering the drive. When used inside incubators, confirm the motor is rated for high humidity and heat. Service motor bearings according to the supplier's recommended schedule.

How do I select the right Orbital Microplate Shaker for ELISA Incubation?

Choose this variant for routine ELISA and general plate mixing at room temperature. For temperature-controlled incubations, a thermoshaker is needed, and for 384-well plates consider a small-orbit or double-orbital model. In an RFQ specify speed range, orbit diameter, plate capacity, timer and clamp type.

How does it compare with other Microplate Shakers variants?

Select a microplate shaker by motion type, speed range, orbit diameter and capacity. Orbital shakers with 2 to 3 millimeter orbit suit ELISA incubations and general mixing. Double-orbital or small-orbit models suit 384- and 1536-well plates, where splashing limits speed. Thermoshakers add heating and cooling for temperature-sensitive incubations. Check the plate carrier for your formats, including deep-well plates, and maximum load for stacked plates. Confirm low-speed stability for cell suspensions and high-speed performance for bead mixing. For incubators, choose models with low heat output and appropriate IP rating for humidity. Consider noise, timer and programmable profiles, and whether integration with automation requires open-lid access or a communication interface.
