Why do you need a humidity chamber for IHC and ISH?
The humidity chamber is critical in Immunohistochemistry (IHC) and In situ hybridization (ISH) for 2 main reasons:
1. Prevent drying out
The humidity chamber prevents sample slides from drying out during incubation (IHC) or hybridization (ISH) steps. Drying out can lead to nonspecific binding, high background staining, and poor quality of staining
2. Optimal reaction conditions
- Many IHC reagents evaporate when left exposed to air, and your tissue samples have a tendency to dehydrate. For the antigen-antibody reaction, you need adequate humidity for reagents to remain in liquid form and in contact with the tissue in order for antibodies and their target antigens to interact.
- In situ hybridization can only happen in a temperature and humidity controlled environment for the nucleic acid probes to hybridize to their complementary sequences in the tissue or cells.

Controlled humidity for reproducible results
- Your reagents might evaporate
- Your samples would dehydrate
- You could have inconsistent staining
Variation in humidity leads to inconsistent results. The humidity chamber gives you a controlled environment for every protocol, without any woulda, coulda.

Performance:
- HCN4-24: +/-0.5°C @ +4°C to +70°C. The published temperature variation is derived from the maximum deviation of the thermocouple located nearest the chamber geometric center during the entire test period. (i.e., +25.0°C min and +26.0°C max divided by two would be a variation of +/-0.5°C).
- HCN4-24GD: Temperature Variation: +/-0.5°C @ +20°C to +60°C. The published temperature variation is derived from the maximum deviation of the thermocouple located nearest the chamber geometric center during the entire test period. (i.e., +25.0°C min and +26.0°C max divided by two would be a variation of +/-0.5°C).
- HCN4-52: Temperature Variation: +/-0.5°C @ +4°C to +70°C. The published temperature variation is derived from the maximum deviation of the thermocouple located nearest the chamber geometric center during the entire test period. (i.e., +25.0°C min and +26.0°C max divided by two would be a variation of +/-0.5°C).
- HCN4-52GD: Temperature Variation: +/-0.5°C @ +20°C to +60°C. The published temperature variation is derived from the maximum deviation of the thermocouple located nearest the chamber geometric center during the entire test period. (i.e., +25.0°C min and +26.0°C max divided by two would be a variation of +/-0.5°C).
Temperature Uniformity:
- HCN4-24: +/-1°C @ +4°C to +70°C. The published temperature uniformity is derived from the maximum deviation of 9 thermocouples are placed on 3 horizontal planes, each plane having the thermocouples evenly spaced diagonally across the shelf from the left and right inner wall, and the middle sensor placed in the approximate geometric center of the shelf.
- HCN4-24GD: +/-1°C @ +20°C to +60°C. The published temperature uniformity is derived from the maximum deviation of 9 thermocouples are placed on 3 horizontal planes, each plane having the thermocouples evenly spaced diagonally across the shelf from the left and right inner wall, and the middle sensor placed in the approximate geometric center of the shelf.
- HCN4-52: +/-1°C @ +4°C to +70°C. The published temperature uniformity is derived from the maximum deviation of 9 thermocouples are placed on 3 horizontal planes, each plane having the thermocouples evenly spaced diagonally across the shelf from the left and right inner wall, and the middle sensor placed in the approximate geometric center of the shelf.
- HCN4-52GD: T+/-1°C @ +20°C to +60°C. The published temperature uniformity is derived from the maximum deviation of 9 thermocouples are placed on 3 horizontal planes, each plane having the thermocouples evenly spaced diagonally across the shelf from the left and right inner wall, and the middle sensor placed in the approximate geometric center of the shelf.
Humidity Variation:
- HCN4-24: +/-3% @ +4°C to +70°C (humidity-controlled range) and RH within performance graph. Humidity variation is derived from the maximum deviation of the humidity sensor during the test period.
- HCN4-24GD: +/-3% @ +20°C to +60°C (humidity-controlled range) and RH within performance graph. Humidity variation is derived from the maximum deviation of the humidity sensor during the test period.
