MBIND Laboratory Incubator · Natural Convection · 45 to 210 L
The MBIND laboratory incubator keeps bacteria and other cultures at a stable temperature from 5 °C above room temperature up to 70 °C, with ±0.5 °C fluctuation. Natural convection without a fan, a microcomputer PID controller with auto-tuning and a double door with an inner tempered glass door are common to all four sizes: 45 L (PRO3333), 65 L (PRO3334), 125 L (PRO3335) and 210 L (PRO3336).

All four sizes share the same controller, the same double door and natural convection; they differ in chamber size and heating power. A stainless-steel chamber is available for every size. Not sure which size you need? Send the vessel type and how many you incubate at once, and we will propose the model.
Microbiological incubator with natural convection
Heat rises from the elements under the chamber and spreads through the chamber by itself — there is no fan. Samples do not dry out and no air is blown across open plates. The inner tempered glass door with a silicone seal lets you check the cultures without letting the heat out; the outer door closes with a magnetic seal.

- Research in biology and biochemistry
- Teaching and training laboratories
Why choose a natural-convection incubator
For most bacterial cultures at 30–37 °C, a quiet chamber without forced air is the safer choice: agar plates and open vessels lose less water, and nothing blows spores or aerosols around the chamber. The PID controller learns the heating behaviour of the chamber with auto-tuning, so the temperature stays within ±0.5 °C.
The user manual shows a 9-point temperature map at 37 °C with values from 35.95 °C to 37.26 °C, and heating from room temperature to about 60 °C in 30 minutes (65 L). Keep the setpoint at least 5 °C above the room and load the shelves to no more than one third of their area, so the warm air can rise freely.

Operating functions
PID control and timer
The upper display shows the measured temperature, the lower one the setpoint. The timer runs from 0 to 9999 minutes; at 0 the incubator works continuously, at the end of a timed run the display shows End and the buzzer sounds.
Auto-tuning
At a new working temperature, start the auto-tuning: the controller measures how the chamber heats up and sets its own PID parameters, so the temperature settles without overshoot.
Safety
If the temperature rises above the alarm limit, the buzzer sounds, the alarm light comes on and the heating is switched off. Internal parameters are protected by a password.
Construction, installation and care
The housing is made of cold-rolled steel sheet with a coated surface. The chamber is coated cold-rolled steel as standard, or stainless steel on request — the better choice if you disinfect the chamber often.
Place the incubator level, away from direct sun and other heat or cold sources, with free space to the wall, and connect it to an earthed 220–240 V socket. Clean with a neutral detergent and a dry cloth; do not use acids or alkalis.
