MBIN18 Small Laboratory Incubator · 18 L · Natural Convection
The MBIN18 small laboratory incubator is a compact 18 L incubator for routine microbiological work on a small bench. It holds the temperature from 5 °C above room temperature up to 65 °C with ±0.5 °C fluctuation and 1 °C uniformity. Natural convection without a fan, a PID controller with self-tuning and a Pt100 sensor, and a glass window in the door (order code PRO3141).
Compact microbiological incubator for the bench
Heat spreads through the 260 × 260 × 260 mm chamber by itself — there is no fan, so open plates do not dry out and nothing blows aerosols around the chamber. The glass window in the door lets you check the samples without letting the heat out. On the bench the MBIN18 takes only 380 × 455 mm.
Key features
- Temperature RT+5 °C to 65 °C, fluctuation ±0.5 °C, uniformity 1 °C
- Natural convection, no fan — gentle on open plates
- Two-section PID controller with self-tuning, Pt100 sensor, LED display
- Timer 0 to 9999 min with timing wait and automatic stop
- Over-temperature sound and light alarm
- Glass observation window in the door
- 2 shelves supplied, up to 6, 2 kg per shelf
- Galvanized steel chamber; stainless-steel chamber on request
Suitable for
- Routine microbiological incubation in small laboratories
- Backup capacity for peak load, validation work or service periods
- Sample incubation in pharmacy, industry, medicine and research
- Teaching laboratories — students can follow the samples through the window
Why a small natural-convection incubator
Many laboratories incubate only a few racks of plates at a time. A small 18 L chamber heats up quickly, takes little bench space and uses only 0.15 kW. Without forced air, agar plates and open vessels lose less water.
The two-section PID controller heats fast to the setpoint and then holds it without overshoot; self-tuning adapts the control to the chamber, and the Pt100 reading can be corrected against a reference thermometer. Keep the setpoint at least 5 °C above the room and leave space around the vessels so the warm air can rise.

Typical values, measured without load. The setpoint must be at least 5 °C above room temperature.
Operating functions
PID control and timer
The LED display shows the measured and the set temperature. The timer runs from 0 to 9999 minutes; with timing wait it starts only when the setpoint is reached, and at the end of the run the heating stops automatically.
Safety and settings
An over-temperature sound and light alarm protects the samples. Internal parameters can be locked, and all settings are kept after a power cut.
Temperature certificate
Every MBIN18 comes with a temperature certificate at 40 °C in the chamber centre, issued by COLO technical service. One-point or multi-point mapping by an accredited laboratory is available on request.
Construction, installation and care
The housing is cold-rolled steel with an electrostatic powder coating. The chamber is galvanized steel as standard, or stainless steel on request — the better choice if you disinfect the chamber often. The Ø28 mm exhaust flap on top also serves as a test hole for a reference probe.
Place the incubator level, away from direct sun and other heat or cold sources, and connect it to an earthed 220 V socket. Clean with a neutral detergent and a dry cloth.

Is 18 L the right size?
- MBIN18, 18 L — one user, a few racks of plates or tubes, limited bench space.
- Need more space? See the MBIND incubator series, 45 to 210 L.
- Need forced air circulation? See the MBINE incubator series.
Configuration note
Tell us the vessels, how many you incubate at once and your working temperature, and whether you need a stainless-steel chamber, data output or a mapping certificate. COLO.Science will confirm the configuration in the quotation.
