Application-Specific FAQ
Q: Is this RCS unit compatible with the TA Instruments Discovery DSC 2500?
A: Compatibility depends on the specific DSC platform generation. Please confirm your instrument model number with our technical team before ordering — contact [email protected] with your DSC serial number for verification.
Q: What is the lowest temperature this system can achieve?
A: The 135SR RCS is rated for subambient operation; exact minimum temperature depends on the paired DSC instrument and ambient lab conditions. Typical lower limit is approximately -90°C when paired with compatible TA Instruments DSC platforms.
Q: Can this unit operate on 50Hz mains power?
A: This specific SKU (220 60Hz) is configured for 60Hz operation. For 50Hz environments, a separate SKU or step-frequency converter is required. Contact us for the appropriate 50Hz variant.
Q: Does this unit require liquid nitrogen?
A: No. The RCS uses mechanical refrigeration (compressor-based), eliminating the need for liquid nitrogen or dry ice — a key operational advantage for continuous-use laboratory environments.
Q: What warranty applies to this product?
A: Konmask.com provides a standard hardware warranty on all OEM parts. Extended warranty and calibration service options are available — please inquire at the time of order.
Q: Can you provide a Certificate of Conformance (CoC) or material traceability documentation?
