Shaking Microplate Incubator for Bacterial Culture

What is the Shaking Microplate Incubator for Bacterial Culture?

A shaking microplate incubator for bacterial culture combines controlled temperature, often 25 to 60 degrees Celsius, with orbital shaking of 500 to 1,200 revolutions per minute to aerate cultures in 96- and deep-well plates. It is used for microbial growth, screening and expression.

Overview

This variant integrates a thermostatted chamber with a high-speed orbital shaker of 3 millimeters or larger orbit, strong enough to supply oxygen to bacterial cultures in microplates. Typical speeds are 500 to 1,200 revolutions per minute, temperature ranges from ambient plus 5 to 60 degrees, and platforms hold 2 to 12 plates or deep-well blocks with clamps. Humidity cassettes and breathable films control evaporation, while deep-well plates allow 0.5 to 2 milliliter cultures with better oxygen transfer. Optional optical density readers are built into some models for continuous growth monitoring. Because faster shaking increases splashing and cross-contamination risk, sealed breathable films are essential. Noise, vibration and heat output should be checked, and the units are not designed for CO2-dependent mammalian cells.

How does it work?

Microplate incubators maintain a uniform thermal environment around plates. Forced-air designs circulate heated air through the chamber with a fan, heater and a platinum resistance sensor feeding a PID controller, giving uniformity within about plus or minus 0.5 degrees Celsius. Dry-block designs conduct heat from an aluminum block that contacts the plate base, with Peltier elements for heating and cooling. Humidity is generated by a water reservoir or ultrasonic humidifier and monitored by a sensor, preventing evaporation from wells. CO2 incubators add infrared or thermal conductivity sensors and gas solenoid valves to hold 5 percent carbon dioxide for bicarbonate-buffered media. Shaking incubators combine these conditions with orbital motion. Door seals, insulation and heated lids limit gradients and condensation, which otherwise produce edge effects between outer and inner wells.

What are the key features?

• High-speed orbital shaking at 500 to 1,200 revolutions per minute
• Temperature range of ambient plus 5 to 60 degrees Celsius
• Clamps for 2 to 12 plates or deep-well blocks
• Humidity cassettes and breathable film to limit evaporation
• Optional built-in optical density monitoring
• Deep-well plate support for 0.5 to 2 milliliter cultures

What are the technical specifications?

A typical shaking microplate incubator for bacterial culture configuration offers temperature range of Ambient +5 to 60 °C, temperature uniformity of ±0.5 °C, speed range of 500–1,200 rpm, orbit diameter of 3–25 mm (model dependent), plate capacity of 2–12 plates and culture volume of 100–2,000 µL/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 Shaking Microplate Incubator for Bacterial Culture is used in bacterial growth curves in plates, antibiotic susceptibility incubation, recombinant protein expression screening, yeast and microbial strain screening and biofilm growth. Across the wider Microplate Incubators class, laboratories also deploy it for ELISA and immunoassay incubation, bacterial growth and susceptibility testing and mammalian cell culture in plates.

Which standards and certifications apply?

Relevant standards and methods include IEC 61010-1, IEC 61010-2-010, IEC 61326-1, ANSI/SLAS 1-2004 to 4-2004, ISO 13485 (IVD workflows) and EN 12469 (for biosafety-related enclosures, where applicable). 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.

Install on a level surface away from drafts, direct sunlight and heat sources, with clearance for ventilation. Map temperature with calibrated probes in loaded and empty conditions at installation and periodically, and record set point drift. Use distilled or deionized water in humidity reservoirs and clean them regularly to prevent microbial growth. Clean interior surfaces with disinfectants compatible with the chamber material, and run sterilization cycles where available. Avoid frequent door openings, and allow recovery time for temperature and CO2. Calibrate CO2 sensors against a reference analyzer, and keep alarms active for unattended runs.

How do I select the right Shaking Microplate Incubator for Bacterial Culture?

Choose this variant for microbial growth and screening in plates needing aeration and temperature control. For mammalian cells use a CO2 incubator. In an RFQ specify temperature range, speed, orbit, plate capacity, deep-well support and optional OD monitoring.

How does it compare with other Microplate Incubators variants?

Match the incubator to assay temperature, duration and atmosphere. Dry-block or forced-air models are enough for ELISA and binding steps at 25 to 37 degrees. Use a humidified chamber for long incubations to limit evaporation. Mammalian cell assays need CO2 and humidity control, while bacterial growth may need shaking and temperatures up to 60 degrees. Check capacity in plates, uniformity and recovery time after door opening, plus cooling below ambient for refrigerated incubations. Consider footprint, compatibility with stackers and readers, contamination control features such as HEPA filtration or copper surfaces, data logging and alarms. For regulated laboratories, verify temperature mapping documentation, calibration certificates and audit trail capabilities.
