1) up to 98 % of the set value
2) These values can be used for dimensioning air condition systems.

All technical data are specified for units with standard equipment at an ambient temperature of 25 °C (77 °F) and a line voltage fluctuation of ±10%. The temperature data is determined in accordance to factory standard following DIN 12880, respecting the recommended wall clearances of 10% of the height, width and depth of the inner chamber. All figures are typical average values for series devices. We reserve the right to alter technical specifications at any time.

BINDER Gas Supply Service

BINDER Gas Supply Service

The external tank changer makes automatic changeover to a second tank possible once the first tank is empty. It has acoustic and visual alarms and is equipped with a zero-voltage alarm output for extreme notification systems. It can be used for maximum two CO2 incubators and is suitable for CO2, O2 and N2 tanks.

Gas-tight, 4-way divided inner glass door

Gas-tight, 4-way divided inner glass door

For stable climate conditions in the broad chamber. Minimal loss of humidity, heat, and CO2 when loading. Ensures short recovery times.

Control for variable O2 values

Control for variable O2 values

For hyper- or hypoxic culture conditions. The O2 or N2 gas supply can be controlled using an additional control loop as needed. A zirconium oxide sensor (ZrO2) is used for the measurement.

Silicone access ports

Silicone access ports

For introducing external measuring instruments into the chamber. The access ports have a diameter of 30 mm (1.2 inch) and can be sealed on both sides using a silicone plug. They can be positioned on the back, left, and right sides.

Stacking adapter

Stacking adapter

Used for stacking of two CB incubators which are thermally isolated from each other. The incubators can thus be sterilized with hot air independent of each other. Available as stacking adapters, stacking frames or base frames.

APT-COM™ DataControlSystem GLP Edition

APT-COM™ DataControlSystem GLP Edition

Software for GLP-compliant control, programming and documentation. Allows networking of up to 30 devices or controllers. Meets FDA 21 CFR Part 11 requirements.

Calibration certificate & validation

Calibration certificate & validation

BINDER can significantly reduce the workload in qualifying and validating devices. Nobody knows our devices as well and has as much experience in certifications as we do.
