Microplate Shaker Incubator for Cell and Microbial Growth

What is the Microplate Shaker Incubator for Cell and Microbial Growth?

A microplate shaker incubator holds plates at controlled temperature and often humidity while shaking, supporting bacterial growth, suspension cell culture and long enzymatic incubations. It is used where plate cultures need temperature stability from ambient to about 60 degrees for hours to days.

Overview

This variant is an enclosed chamber with a shaking platform, forced-air or conduction heating, and often a cooling option and humidity control. Typical chamber temperatures range from ambient minus 5 degrees to 60 or 70 degrees Celsius, with uniformity within plus or minus 0.5 to 1 degree, and shaking speeds from 100 to 1,200 revolutions per minute with orbit of 3 millimeters. Capacity ranges from 2 to 12 plates on a platform or stacked trays. A condensation-free transparent lid or window allows visual inspection, and a humidity reservoir reduces edge effects over 24 to 72 hours. Gas control for carbon dioxide is available on some models, but many are for air-only bacterial and yeast work. Compared with a reader, it has no optical measurement, so growth must be assessed in an external reader or by sampling. Larger footprint and longer stabilization time are practical considerations.

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?

• Enclosed chamber from ambient minus 5 to 60 degrees Celsius
• Orbital shaking at 100 to 1,200 revolutions per minute with 3 millimeter orbit
• Holds 2 to 12 microplates on platform or stacked trays
• Humidity reservoir reduces edge effect in 24 to 72 hour runs
• Transparent window and interior light for visual inspection
• Optional CO2 control on selected models

What are the technical specifications?

A typical microplate shaker incubator for cell and microbial growth configuration offers temperature range of Ambient −5 to 60 °C, temperature uniformity of ±0.5–1.0 °C, speed range of 100–1,200 rpm, orbit diameter of 3 mm, plate capacity of 2–12 plates (96-well) and humidity control of Reservoir, up to 80% RH (typical). 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 Microplate Shaker Incubator for Cell and Microbial Growth is used in bacterial and yeast growth in microplates, antimicrobial susceptibility incubation, suspension cell culture in plates, long enzymatic incubations and biofilm formation 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 Microplate Shaker Incubator for Cell and Microbial Growth?

Choose this variant for multi-plate, multi-hour cultures or incubations that need stable temperature and shaking without a reader. If you need continuous optical readout, choose a reader with incubation and shaking instead. In an RFQ specify temperature range, plate capacity, humidity and CO2 needs and shaking orbit.

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.
