As the market competition, facing the requirement of increasing the product quality, precision rectification method is applied to improve the quality of products, many other purification methods is irreplaceable important means of the most economical.Laboratory distillation device is fine chemical industry, daily chemical, light, the pharmaceutical industry, oil refining, chemical and other departments of agriculture and forestry products development, experiment, purified and refined, a necessary device, is also the important experimental equipment of colleges and universities scientific research units.
 
Glass can be used in rectifying tower kettle for closed flask (three, four) or open (below the flask with feeding mouth) used with electrical heating jacket or oil bath;The tower itself using electric heating zone and in the form of coating and heat insulation, voltage can be adjusted manually, the heat preservation effect is good, the tower festival can according to customer's need to open a feed in upper and lower position, temperature, lateral line by export;Use tower head inside outside reflux, reflux, split phase reflow, suitable for the common distillation, extractive distillation, azeotropic distillation and so on a variety of ways;Overhead condenser adopts glass snake tube condenser, heat transfer area is big, strong and reliable quality;Products produced using vacuum receiver plug type, advanced structure, under the often, the condition of reduced pressure can be at ease use;Tower body as a whole can adopt standard mouth connection, ball grinding mouth connection, flange connection, etc. A variety of ways.Reflux ratio control system, according to user requirements to choose simple, precise, data acquisition, computer integrated control and so on a variety of ways;Affiliated fittings can choose different specifications according to customer requirements, feed pump and vacuum pump framework, etc.
 
In the small glass used with, under the condition of reduced pressure distillation device.Single batch capacity of 500 ml, 500 ml - tower section to design temperature measuring and sampling mouth mouth;Customers can use conventional standard configuration, suitable for all kinds of conventional materials, for a variety of material has good separation effect.The tower by electric heating zone and coating in the form of visual (transparent) and heat insulation, voltage can be adjusted manually, the heat preservation effect is good, can be directly observed the tower distillation operation.Rectifying column control system mainly includes the intelligent thermometer (by temperature sensor tower kettle temperature, top temperature, column section temperature, etc.), reflux ratio controller, voltage regulator, etc, mainly aiming at the condition of the various control points in the process of distillation to reflect on the surface. 

Technical parameters (according to customer's requirement)
Tower body diameter: Dg25-100 mm,
Single tower section height: 0.3 ~ 2 m;Pipe wall thickness: 2.5 ~ 10 mm

Backflow of tower head forms: inside outside reflux, reflux
Condenser cooling area: 0.02 ~ 10 m2
Backflow using reflux ratio automatic control, control time of 1-99
Connection mode: direct mill, ball mill, flange flat mouth
Heat preservation method: electric heating, transparent conductive film, semiconductor, mezzanine vacuum insulation asbestos silver, heating wire jacket type, etc
Vacuum pump (by advertisers, when need can act as purchasing agency)
 
Equipment structure
The device consists of process instrumentation control part, tower parts, heating system, vacuum system (according to the actual optional) and the frame system.
Section contains control cabinet of instrument control, remote transmission temperature digital display table, PT100 platinum resistance, u-shaped tube differential pressure gauge, reflux ratio control system, etc.

The component of product:
Glass distillation device is made of glass, reflux ratio control system in the rectification column, column reactor tower heat system, vacuum system, alarm system and control system.Can satisfy the batch distillation, continuous distillation, azeotropic distillation, extractive distillation and the atmospheric and vacuum distillation and other occasions.
Rectification, rectification column, packing, temperature measurement, vacuum unit such as main components, a variety of models available for rotation and with different products.All glassware all adopt standard ground connection, install replacement is very convenient.The connections between glass instrument parts accessories, in addition to the traditional standard ground connection mouth, mouth and air tightness better ball mill connection, especially suitable for vacuum degree is higher required.Reflux ratio controller not only can be used to test small sample in the lab, and simply add some accessories, can be extended for medium and small chemical production make using of the distillation flow control device.
 
The exception, in addition to conventional products, our company can also undertake various non-standard customized business, when necessary, the buyer shall provide production drawings.
 
Product features:
Tower kettle body for glass manufacturing, have sealed tightly, do not leak, acid and alkali corrosion resistance and other properties.Controlled heating temperature can be adjusted, and the tower, tower kettle temperature automatic display, reflux in automatic control.Easy operation, stable running and reliable data.
 
This device is complete sets of equipment, compact structure, beautiful and easy, convenient installation, cover an area of an area small, users only need to prepare the water and power supply, simple installation according to the specification can be put into use.Main glass parts, using standard mouth or ball mill mouth connection between alloy flange fixed, it has excellent air tightness, high vacuum distillation.
 
Digital Settings for distillation vacuum figures show that when the reflux ratio of 99:1/1:99 range, automatic temperature control, digital display, convenient and intuitive.Mounting rack for stainless steel floor derrick structure.
