BUCHI Kjel Line K-365 in Pakistan
The BUCHI Kjel Line K-365 is a modular family of steam-distillation systems for Kjeldahl nitrogen and protein analysis and selected steam-volatile analytes. EasyKjel, BasicKjel and MultiKjel share the same core platform but provide progressively higher levels of dosing, process, disposal and titration automation.
Supplied and supported in Pakistan by Continental Worldwide Trading Company (CWTC).
Choose the Suitable Kjel Line Configuration
EasyKjel
For laboratories that need dependable steam distillation with a straightforward, operator-controlled workflow.
- Colour display and intuitive operation
- Automatic sodium hydroxide dosing
- Adjustable steam power and programmable ramps
- Suitable for established routine Kjeldahl procedures
BasicKjel
For quality-control laboratories seeking more consistent preparation and distillation with reduced manual handling.
- Automatic sodium hydroxide and water dosing
- AutoDist for programmable distillation workflows
- Optional touchscreen and sample disposal
- Can be used with a separate external titration procedure
MultiKjel
For laboratories prioritising the highest automation level and closer integration of distillation, titration and result handling.
- Automatic sodium hydroxide, water and boric acid dosing
- Touchscreen operation and sample disposal
- Optional external titrator connection
- Optional reaction detection and receiver disposal
Selection principle: all three instruments share the K-365 platform. The right model depends mainly on sample throughput, required automation, operator involvement, titration workflow, documentation needs and the laboratory's existing Kjeldahl equipment.

Environmental And Wastewater
Kjeldahl nitrogen analysis in water, wastewater, sludge and environmental samples after appropriate digestion and sample preparation.
Volatile Acids And Bases
Selected applications such as TVB-N in fish and seafood, sulfur dioxide, formaldehyde, volatile acids, ammonia and related steam-volatile analytes.
Method fit matters: final suitability depends on the sample matrix, digestion procedure, nitrogen range, applicable standard, titration approach, throughput and laboratory quality requirements.
Shared Kjel Line Features & Practical Benefits
| Shared K-365 feature | Practical value |
|---|---|
| Reference nitrogen range: 0.02–220 mg N | Supports routine nitrogen and protein work across a broad variety of digested sample types. |
| Adjustable steam power from 10–100% | Allows the distillation profile to be adapted to method and sample behaviour. |
| Programmable steam ramps | Supports controlled heating and helps manage foaming or demanding matrices. |
| MaxAccuracy mode | Provides a workflow route for applications requiring careful, repeatable distillation conditions. |
| Safety and process monitoring | Supports routine operation through instrument checks and monitoring of important workflow conditions. |
| Modular automation | Lets the laboratory select only the dosing, disposal, touchscreen and titration functions it genuinely needs. |
| Resource-conscious operation | Adjustable steam and automated workflows can help standardise water, reagent and operator use. |

Complete Kjeldahl Workflow and Configuration Options
Complete Kjeldahl Workflow
- Sample preparation: accurate weighing and appropriate digestion vessel selection.
- Digestion: compatible SpeedDigester or KjelDigester system, catalyst tablets and fume-management accessories.
- Steam distillation: EasyKjel, BasicKjel or MultiKjel selected around automation needs.
- Titration: manual, separate external or optionally connected workflow depending on the selected model.
- Calculation and reporting: laboratory procedure, printer or data workflow selected around quality requirements.
What Determines The Configuration?
- Sample types and applicable reference methods
- Typical nitrogen range and sample size
- Samples per day and expected peak throughput
- Existing digestion and titration equipment

Frequently Asked Question
All three use the BUCHI K-365 steam-distillation platform. EasyKjel provides essential routine operation, BasicKjel adds automated water dosing and AutoDist, while MultiKjel offers the highest automation level with options such as boric acid dosing, connected titration and reaction detection.
The Kjel Line covers the steam-distillation stage. A complete Kjeldahl workflow may also require a digestion system, scrubber or fume-management accessories, digestion tubes, catalysts, reagents and a manual, separate or optionally connected titration route. CWTC confirms the exact scope in the quotation.
Yes. Kjeldahl nitrogen can be determined using an appropriate validated method and converted to protein using the applicable factor. The digestion procedure, sample size, catalyst, distillation and titration conditions must match the matrix and reference method.
Yes, where an established Kjeldahl or steam-distillation method applies. Final suitability depends on the matrix, digestion procedure, nitrogen range, interferences and the relevant standard or laboratory method.
No. EasyKjel and BasicKjel are normally used with a manual or separate external titration workflow. MultiKjel can be configured with an optional external titrator connection. The exact titration scope must be confirmed for the selected system.
EasyKjel suits straightforward operator-controlled routines. BasicKjel is often the stronger choice where automated water dosing and AutoDist improve repeatability and daily operation. MultiKjel is preferred when the laboratory needs the highest automation level or closer titration integration.
BUCHI specifies a reference nitrogen range of 0.02–220 mg N for the K-365 platform. Practical method performance still depends on the sample, digestion, titration, blanks and the complete analytical procedure.
Requirements may include a BUCHI digestion system, scrubber or fume-management equipment, digestion tubes, catalyst tablets, acids, alkali, boric acid, receiving vessels, standards and a suitable titration workflow. The exact list depends on the application and existing laboratory equipment.
Yes. CWTC supports Kjel Line selection, quotation, supply, installation, operator training, workflow discussion, accessories, consumables, maintenance and after-sales support in Pakistan, subject to the agreed product and service scope.
