BINDER KBF115 Temperature and Humidity Controlled Chamber

Overview

The BINDER KBF115 Temperature and Humidity Controlled Chamber is an upright, precision-engineered environmental test system designed for pharmaceutical stability testing, long-term sample storage, microbiological incubation, and material aging studies under tightly regulated climatic conditions. It operates on a dual-control principle—simultaneous regulation of air temperature and relative humidity—using independent heating, cooling, humidification, and dehumidification subsystems. The chamber employs BINDER’s proprietary APT.Line® pre-heating technology, which thermally conditions supply air in a dedicated pre-chamber before introducing it into the working space, thereby eliminating vertical thermal gradients and achieving exceptional temperature uniformity (±1.0 °C at 37 °C with humidity). Complementing this is the DCT® (Direct Cooling Technology) flat-plate evaporator system, enabling rapid, homogeneous cooling via direct airflow contact—eliminating cold spots and ensuring reproducible thermal transitions. Designed and validated in accordance with ICH Q1A(R3) and Q1B guidelines, as well as EN 60068-3-5 and DIN 12880, the KBF115 meets the stringent requirements of GLP-compliant laboratories and regulatory submissions.

Key Features

• APT.Line® pre-heating technology ensures uniform temperature distribution (±1.0 °C) across the entire 115 L stainless steel interior (600 × 480 × 400 mm)
• DCT® direct-cooling system with large-surface flat-plate evaporator enables fast, stable cooling without localized overcooling
• MCS microcontroller with 25 programmable protocols (100 segments each), supporting complex multi-step climate profiles
• Capacitive humidity sensor offering high accuracy (±1.5 % RH fluctuation), drift-free performance, and zero-maintenance operation
• Electrode-type humidifier compatible with standard tap water (200–500 µS/cm conductivity); integrated automatic water level monitoring and dry-run protection
• Class 3.1 independent temperature safety device (DIN 12880) with visual and audible alarm, configurable threshold
• Double-glazed internal glass door with integrated condensate collection tray minimizes external heat/moisture exchange and prevents fogging
• RS422 interface compliant with BINDER’s APT-COM® software for real-time data acquisition, audit-trail generation, and 21 CFR Part 11–ready electronic records
• Environmentally optimized refrigerant R134a and energy-efficient insulation (polyurethane foam, 70 mm thick)
• Two adjustable stainless steel shelves (20 kg load capacity each), corrosion-resistant and autoclavable

Sample Compatibility & Compliance

The KBF115 accommodates a broad range of sample formats—including Petri dishes, vials, trays, and sealed containers—without compromising environmental integrity. Its smooth, seamless stainless steel interior (AISI 304) resists microbial adhesion and facilitates cleaning validation. The chamber is routinely deployed in stability-indicating studies per ICH Q5C (biotechnology products), Q1A(R3) (stability testing of new drug substances and products), and Q1B (photostability testing). It supports compliance with USP , ISO 14644-1 (cleanroom classification support), and ASTM E145-22 (standard specification for gravity-convection and forced-ventilation ovens). All control parameters—including setpoints, deviations, alarms, and user actions—are timestamped and stored locally with optional export to secure network servers, satisfying GLP/GMP documentation requirements for traceability and audit readiness.

Software & Data Management

The integrated MCS controller provides intuitive navigation via a backlit LCD interface with multilingual menu support (English, German, French, Spanish). Real-time graphical display of temperature and humidity trends is available on-screen, with up to 72 hours of internal data logging (1-minute intervals). For extended monitoring, the RS422 port enables bidirectional communication with APT-COM® software (Windows-based), supporting automated report generation, alarm escalation, user-level access control (three-tier permissions), and electronic signature functionality compliant with FDA 21 CFR Part 11 Annex 11. Raw data files are exported in CSV or XML format, preserving metadata such as operator ID, calibration status, and environmental deviation flags—critical for regulatory inspection preparedness.

Applications

• ICH-compliant long-term and accelerated stability testing of APIs, finished pharmaceuticals, and biologics
• Microbial growth studies and controlled bacterial/fungal cultivation under defined hygrothermal conditions
• Material compatibility and packaging integrity assessment (e.g., moisture barrier evaluation)
• Accelerated aging of polymers, adhesives, and electronic components per IPC-9701 and JEDEC JESD22-A119
• Seed germination, plant tissue culture, and entomological rearing requiring precise humidity modulation
• Calibration verification of hygrometers and reference standards in metrology labs
• Pre-conditioning of test specimens prior to mechanical or electrical characterization (e.g., ASTM D618)

FAQ

What ICH guidelines does the KBF115 comply with for stability testing?
The KBF115 is engineered and validated to meet the environmental control specifications outlined in ICH Q1A(R3) and Q1B, including temperature uniformity, humidity accuracy, and recovery time requirements after door openings.
Can the KBF115 operate continuously for extended periods (e.g., 6-month stability studies)?
Yes—the system features an automatic defrost cycle, redundant safety controls, and robust compressor design optimized for uninterrupted 24/7 operation. Preventive maintenance intervals are specified at 12 months under typical lab use.
Is tap water sufficient for humidification, or is distilled water required?
The electrode-type humidifier is specifically calibrated for tap water with conductivity between 200–500 µS/cm. Distilled or deionized water is incompatible and will disable humidification.
Does the KBF115 support 21 CFR Part 11 compliance?
When used with APT-COM® software and configured with user authentication, electronic signatures, and audit-trail logging, the system satisfies key technical controls for Part 11 compliance. Full validation documentation (IQ/OQ/PQ templates) is available upon request.
What is the maximum permissible load volume without compromising performance?
For optimal thermal and humidity uniformity, BINDER recommends loading no more than 60% of internal volume (≤69 L) with non-porous samples. Porous or high-surface-area materials may require derating based on moisture adsorption kinetics.
