The STN Stainless-Steel Thermal Capsule works with temperature probes to provide a liquid-free thermal buffer inside temperature-controlled environments. By minimizing short-term temperature fluctuations, it ensures more stable and representative temperature readings. This is especially critical for vaccine storage, pharmaceutical cold chains, and laboratory chambers, where even minor temperature excursions can compromise product integrity. Its rugged stainless-steel design ensures durability, easy cleaning, and long service life in demanding monitoring applications.
Traditionally, pharmaceutical storage uses glycol-filled bottles to dampen transient spikes from frequent door openings. However, liquid buffers introduce issues, evaporation, spillage, and periodic refilling as well as the inconvenience to insert a standard probe during annual calibration.
Our stainless-steel thermal capsule eliminates these problems: it’s liquid-free and maintenance-free, features a hygienic, wipe-clean design, and includes a second connector for easily inserting a reference probe. It provides thermal buffering performance comparable to glycol bottles without the mess or downtime (validated by test results, please see diagram below).
Key Features & Benefits
- Superior Temperature Stability – Effectively minimizes fluctuations for more reliable readings.
- Wide Compatibility – Suitable for storage conditions from high temperature down to -80 °C.
- Liquid-Free Design – No risk of spills, evaporation, or maintenance.
- Durable & Hygienic – Constructed from 304L stainless steel for longevity and easy cleaning.
- Flexible Probe Integration – Accommodates up to two probes (Ø6 mm max) with replaceable probe holders and custom connector options.
- Convenient Design – Detachable bottom allows quick inspection of probes inside.
Smart Probe Management
The thermal capsule features two top connectors:
- One for the probe monitoring chamber temperature.
- One optional port for an additional probe, such as a standard probe for calibration.
Both connectors are detachable, and STN provides custom connector options to fit different probe sizes. The capsule also has a detachable bottom, allowing easy inspection of probes inside.
With its precision engineering and user-friendly design, the STN Thermal Capsule as a thermal buffer block is the ultimate substitute for glycol-filled bottles—ensuring stability, accuracy, and peace of mind for critical cold-chain applications
