FAQ
What are the main applications of the Graphite Kjeldahl Digester?
The Graphite Kjeldahl Digester is used for a defined chemical preparation step such as digestion, extraction, evaporation or distillation. It supports analytical, environmental, food, pharmaceutical and teaching laboratories following standard procedures.
Which standards and regulations apply to the Graphite Kjeldahl Digester?
The apparatus is designed with reference to IEC 61010 electrical safety and relevant ISO and GB/T standard methods for the specific procedure. Glassware and heating must match the method. Compliance documentation can be provided on request.
What does the warranty cover?
The complete unit carries a 12-month warranty from delivery, covering the main body, core components and controller against manufacturing defects. Consumables and wearing parts such as filters, seals and probes are not covered. Damage from misuse, improper power or unauthorised repair is excluded, and extended warranty can be quoted.
How easy is the Graphite Kjeldahl Digester to use?
No advanced specialist skills are needed for standard operation, though correct sample handling and safety practice should be followed. We supply a detailed manual and start-up support. For multi-user or regulated sites, a short staff training session can be arranged.
How long does delivery usually take?
Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
How often should the Graphite Kjeldahl Digester be calibrated?
Regular calibration keeps measurements within the stated accuracy; an annual check is typical, with shorter intervals for heavy or regulated use. Reference standards and procedures are described in the manual. We can quote calibration with certificates.
Are the consumables universal or proprietary?
The instrument uses standard, widely available consumables rather than special locked items. Replacement parts, accessories and consumables can be ordered from us against the model number. We keep common service parts in stock for prompt supply.
Can the Graphite Kjeldahl Digester be customised?
A range of options is available to match the application, such as alternative settings, fittings, data outputs or power supply. We confirm each option and its effect on price and schedule up front. Larger custom builds can be discussed.
How is the Graphite Kjeldahl Digester commissioned?
Standard installation is straightforward and supported by the manual and start-up documentation. Our technical team can guide staff remotely through checks and validation. On-site commissioning is available as a quoted service.
What maintenance and safety points matter?
Do not use incompatible or damaged glassware, exceed temperature or pressure limits or work without ventilation for fuming samples. Follow the standard method and safety rules.
