Our guide to choosing the climate chamber best suited to your needs.
In summary: A benchtop climatic chamber is a compact instrument for controlled environmental testing (temperature, humidity) with typical volumes between 25 and 200 liters, which can be placed directly on a laboratory surface. It offers the same technical performance as floor-standing chambers (range -70°C to +180°C, humidity 10-98% RH) in a smaller footprint, and is the preferred option for R&D, pharmaceutical laboratories, electronics, and small-scale components. FDM produces 25, 50, 140, and 200-liter benchtop chambers compliant with ICH Q1A/B, IEC 60068, and MIL-STD-810.
A benchtop environmental chamber (or benchtop environmental chamber) is a laboratory apparatus designed to simulate controlled conditions of temperature and relative humidity within a compact volume, typically between 25 and 200 liters, with external dimensions such that it can be installed directly on the work surface.
This is in contrast to floor-standing climate chambers (cabinets ranging from 300 liters to several m³) and walk-in chambers accessible to the operator, which can contain entire vehicles or aerospace components.
The deciding factor in choosing a test is not the quality of the test, but the size of the sample: a benchtop chamber performs the same thermal and hygrometric profiles as a large chamber, without compromising on performance.
| Parameter | Typical benchtop camera range |
|---|---|
| Internal volume | 25 – 200 liters |
| Temperature range | -70°C ÷ +180°C (high-end configuration) |
| Relative humidity range | 10% – 98% RH (at 10-95°C) |
| Thermal uniformity | ± 0.5 °C (ICH compliant) |
| Thermal stability | ± 0.3 °C |
| Ascent/descent ramp | 3 – 15 °C/min |
| Weight | 60 – 150 kg (transportable on wheels) |
| Diet | 230V single-phase (models <50 L) or 400V three-phase |
The most advanced models integrate touch screen programmers (revoFACE FDM), USB/Ethernet data logging, 21 CFR Part 11 audit trail , deviation alarms and multi-step programmable temperature profiles
Benchtop climatic chambers cover practically all the uses of larger chambers, limited by the sample volume:
1. Small footprint. Compact models fit on a laboratory benchtop (typical dimensions 70 cm high × 80-100 cm wide × 70 cm deep), freeing up valuable space. A 50 L benchtop chamber replaces a 500 L cabinet when the sample size allows.
2. Portability. Weighing under 100-150 kg, many benchtop chambers are wheeled and can be moved between departments. For companies with distributed laboratories, this is a truly shared investment.
3. Lower energy consumption. Smaller volume means reduced thermal load: a 25 L chamber typically consumes 5-8 times less than a 250 L cabinet at the same set point.
4. Simplified installation. Many models up to 50 L operate on a single-phase 230V power supply, eliminating the need for dedicated three-phase systems—a significant advantage in R&D laboratories.
5. No compromise on performance. The evolution of refrigeration and heating technology and compact exchangers has led to the latest-generation countertop chambers achieving performance equal to or superior to floor-standing models: fast ramps, extended ranges, and top-of-the-line uniformity.
The choice of a floor chamber becomes obligatory when:
For all other scenarios, the benchtop chamber is the most rationally efficient choice.
FDM Environment Makers for over 70 years benchtop environmental chambers in a variety of configurations
All FDM chambers integrate the revoFACE, multi-threshold alarms, GMP-compliant data recording, and are IQ/OQ/PQ according to ICH Q1A/B. For specific needs, FDM creates custom benchtop chambers with extended ranges and dedicated configurations.

For cell cultures and CO₂ incubation tests, FDM develops CO₂ test chambers with internal atmosphere control.
The minimum commercial volume is 25 liters, sufficient for samples up to approximately 20x25x40 cm. Smaller models (8-15 L) exist, but with limited temperature ranges and without humidity control: they are closer to incubators than true climate chambers. For ICH Q1A/B or IEC 60068 tests with full T+RH, 25 L is the minimum sensible size.
Yes, as long as it meets the required tolerances: ±2°C for temperature and ±5% RH for humidity at ICH set points (25°C/60%, 30°C/65%, 40°C/75%). Benchtop FDM chambers achieve tighter tolerances (±0.5°C, ±2.5% RHqualified IQ/OQ/PQ. The only limit is the volume capacity for the product batches tested.
Prices range from approximately €8,000-12,000 for a basic 25 L model (temperature only, range -20/+80°C) up to €25,000-40,000 for a 50-100 L model with humidity, extended range -70/+180°C, and an advanced programmer. Custom configurations (combined vibration, altitude, controlled atmosphere) start at €50,000. FDM provides personalized quotes via request for a quote.
An incubator typically operates between +5°C and +60°C, with no or limited humidity control (upper range only). A benchtop climate chamber covers much wider ranges (often -40/+150°C), with humidity control from 10-95% RH and programmable multi-step ramps. For pharmaceutical stability tests, shelf life tests, and electronic stress tests, a true climate chamber is needed; for cell cultures or biological incubation, an incubator is sufficient.
