Domestic Laiheng automatic Kjeldahl nitrogen analyzer

L-805Kjeldahl nitrogen

L-805The automatic Kjeldahl nitrogen analyzer is a product with a novel design, complete functions, and higher degree of automation,The instrument is equipped with three independent quantitative pumps for automatic dilutionAutomatic acid and alkali addition, distillationEmptying waste liquid from digestive tractThe function does not require personnel to be on duty throughout the entire process.Multiple security protectionsfunctionFully demonstrating the consideration of humanization in Sanpin Sci Tech Innovation,The all Chinese LCD display is concise, intuitive, and easy to operate. The corrosion-resistant and acid alkali resistant material of the casing greatly improves the service life of the instrument. It can be widely used for the analysis of nitrogen white matter, ammonia nitrogen and other direct distillation methods in feed, soil fertilizer, grain, food, hygiene, chemical industry, teaching, etc.

Features and functions

●Using three independent quantitative pumps to achieve automatic water dilutionAutomatic acid and alkali addition, distillationDrain the waste liquid from the digestive tract,no need

Contact with reagents, distillation end system alarm prompt.

●Tap water access: The instrument can be directly connected to municipal tap water, avoiding ammonia in tap water through the internal water treatment unit of the instrument

The influence of nitrogen composition on experimental results, while also avoiding the phenomenon of steam generator scaling due to calcium and magnesium ions, is beneficial for customerssection

Saved fundsIt also eliminates the tedious operations of buying or making water and replenishing equipment. (Optional)

●To prevent possible splashing of the solution during alkaline distillation, a splash proof and corrosion-resistant cover is installed above the sample tube mouth.

●Innovative exterior design, high-definition LCD display screen, fully Chinese interface, easy to operate.

● The consideration of corrosion-resistant materials ensures the durability of the instrument.

●Multiple automatic safety protection measures ensure the normal and safe operation of the instrument:

Cooling water shutdown protection:When the instrument is running and there is a water outage or interruption in the tap water supply, the instrument will automatically stop running to prevent the splashing of uncooled steamHurt someone.

Distiller water shortage protection:The distiller has an automatic water replenishment function. When the water bucket supplied to the distiller is short of water, the distiller automatically stops running to preventStop the dry burning of the distiller

Damaged.

Security door protection:Corrosion resistant transparent safety door, allowing observation of the entire distillation process. When operating, if the safety door is not closed, the instrument will lock the run button,Provide security protectionProtect.

Test tube out of place protection:When the instrument is running, if the system detects that the test tube is not in position, it will stop running and give an alarm to prevent the alkaline solution from overflowing.

L-149K06/K12/K20seriesFast infrared high-temperature digestion furnace

L-149K06/K12/K20The Type Rapid Infrared High Temperature Digestion Furnace is an ideal design that combines far-infrared heating with a solid graphite material coated with special anti-corrosion materials. It fully embodies the characteristics of fast infrared heating speed, durable heating elements, uniform heating of graphite materials, and high temperature resistance. It is an ideal digestion equipment for samples such as grains, feed, food, soil, fertilizers, and biotechnology. Users can choose a 6-well, 12 well, or 20 well digestion furnace according to different laboratory requirements.

Features and functions

●Adopting far-infrared heating method, the heating speed is fast, and the maximum temperature can reach 650 ℃, with a long service life.

●The conduction material of the digestion furnace is made of high-quality graphite material that has undergone anti-corrosion treatment, with uniform heating and high temperature resistance; The exterior is made of stainless steel, which is aesthetically pleasing and corrosion-resistant.

●Good insulation material, with a furnace temperature of 400 ℃ and an outer shell temperature not exceeding 50 ℃, ensures the safety of users.

●Multiple digestion methods can be preset, and multiple step heating modes (up to 4 steps) can be set for special heating requirements. The heating program can be automatically stored, and there is a sound prompt function after digestion is completed.

●SPTThe series of fast infrared high-temperature digestion furnaces come in three specifications: 6-hole, 12 hole, and 20 hole to meet different user needs.

●Equipped with a highly sensitive temperature sensor, the sample temperature is accurately controlled, with constant temperature stability and temperature fluctuations less than 1 ℃.

●Optional exhaust emission device to elevate sample temperatureThe acid gas generated during the digestion process is concentrated and discharged by an external water flow extraction device to prevent personnel from inhaling harmful gases. At the same time, it alsoAvoid acidic gas pollution to the environment.
