The kilo-lab system is essentially designed to minimize the gap in capacity between laboratory and pilot plant and assembled in smaller volume high-value-added products. This equipment is designed to serve to the per-clinical requirements and needs of the pharmaceutical application. Glass Reactors Kilolab is multi-purpose pilot plant units having pliability of utility. Therefore, though termed Kilolab from a constructional view point they in fact, serve as Flexi Units.
K-JHIL Scientific Jacketed Glass reactors or mixing vessels are frequently used for stirring, dissolving, mixing, extraction and other processes in kilo-lab and pilot plants. Jacketed models are used because it permits heat exchange for better dissolving and crystallization. Mobile mixing vessels can be transported with their component for further processing. They can also be furnished with condensers for vacuum distillation.
Jacketed Reactors are usually primary choice reactors in any scale up lab due to versatility, compact size and smooth operation. The Reactor setup is complete with skid mounted reactor setup with overhead stirrer, reflux condenser, drip system. Several options like Distillation, Separation Receiving, Rectification receiving, Jacket pressure release device; System pressure release device, reactor baffles are available to choose from.

A bioreactor may refer to any system or manufactured engineered device that helps to supports a biologically active environment. Baffle: Baffle is used to break the formation of vortex in the vessel, which is normally highly undesirable as it changes the center of gravity of the system and usually consumes more power.
A Snyder column is an extremely effective air-cooled column used in selected fractional distillations. It is a single glass tube with a series of circular indentations or restrictions in the walls of the cylinder often 3 or 6 in which rest, inverted, the same number of roughly tear-shaped, hollow, sealed glass stoppers; above each point where an inverted tear-shaped stopper rests, the cylinder has further Vigreux-type indentations, in this case serving to limit how high the glass stopper can be raised by vapor flow above its resting place, where, when not raised, it seals the circular opening created by the circular indentation.
A standard application of Snyder columns, is as the condenser and fractionation column above a Kuderna-Danish concentrator, used to efficiently separate a low boiling extraction solvent such as methylene chloride from volatile but higher boiling extract components e. A further air condenser is the Widmer column , developed as a doctoral research project by student Gustav Widmer at ETH Zurich in the early s, a complex type of air condenser combining Golodetz-type concentric tubes and the Dufton-type glass rod-and-wound-spiral at its center see image.
The condenser known as the Liebig type, a most basic circulating fluid-cooled design, was invented by several investigators working independently;  however, the earliest laboratory condenser was invented in by the Swedish-German chemist Christian Weigel — A glass tube carrying vapors from a distillation flask passed through the inner tin tube, not in contact with the cooling water. Weigel subsequently replaced the inner tin tube with a glass tube, and he devised a clamp to hold the condenser.
And he used rubber hoses, instead of metal tubes, to convey water to and from the condenser. The design popularized by Liebig thus consisted of an inner, straight tube surrounded by an outer straight tube, with the outer tube having ports for fluid inflow and outflow, and with the two tubes sealed in some fashion at the ends eventually, by a blown glass ring seal. Its simplicity made it convenient to construct and inexpensive to manufacture, the higher heat capacity of the circulating water versus air allowed for maintaining near to constant temperature in the condenser, and so the Liebig type proved to be the more efficient condenser—capable of condensing liquid from a much greater flow of incoming vapor—and therefore replaced retorts and air condensers.
See Fractional Distillation. A variant of the Liebig condenser having a more slender design, with cone and socket. The fused-on narrower coolant jacket may render more efficient cooling with respect to coolant consumption. The Allihn condenser or "bulb condenser" or simply "reflux condenser" is named after Felix Richard Allihn — A series of bulbs on the tube increases the surface area upon which the vapor constituents may condense.
Ideally suited for laboratory-scale refluxing. A Davies condenser, also known as a double surface condenser, is similar to the Liebig condenser, but with three concentric glass tubes instead of two. This increases the cooling surface, so that the condenser can be shorter than an equivalent Liebig condenser. A Graham condenser also called Grahams or Inland Revenue condenser has a coolant-jacketed spiral coil running the length of the condenser serving as the vapor—condensate path. This is not to be confused with the coil condenser.
The coiled condenser tubes inside will provide more surface area for cooling and for this reason it is most favorable to use but the drawback of this condenser is that as the vapors get condensed, it tends to move them up in the tube to evaporate which will also lead to the flooding of solution mixture.
A coil condenser is essentially a Graham condenser with an inverted coolant—vapor configuration. It has a spiral coil running the length of the condenser through which coolant flows, and this coolant coil is jacketed by the vapor—condensate path.
A Dimroth condenser, named after Otto Dimroth , is somewhat similar to the coil condenser; it has an internal double spiral through which coolant flows such that the coolant inlet and outlet are both at the top. Dimroth condensers are more effective than conventional coil condensers. They are often found in rotary evaporators.
A spiral condenser has a spiral condensing tube with both inlet and outlet connections at top, on same side. A Friedrichs condenser sometimes incorrectly referred to as Friedrich's condenser , a spiraled finger condenser, was invented by Fritz Walter Paul Friedrichs , who published a design for this type of condenser in Coolant flows through the internal cold finger; accordingly, vapors rising up through the housing must pass along the spiraled path. During a fractional distillation in the laboratory or chemical plant , simple straight tubes can be packed with materials to increase surface area, and therefore the number of theoretical plates ; in the same manner, the surface areas of simple laboratory glass condensers such as the Liebig can be filled to improve performance.
Metal packing types can extend to wire packings of nichrome and inconel akin to Podbielniak columns , to stainless steel gauze Dixon rings , and indeed to any of the various special packing methods used in distillation e.

Shown is a Liebig fluid-cooled condenser schematic. Circulating cooling water is shown in blue. The white rectangular area is a cutaway view of the central tube through which vapor and condensate flow, direction of which depends on the procedure. Trapezoids at top and bottom are ground glass joints that connect condenser to rest of apparatus for example, in a reflux, to a boiling flask at bottom, drying tube at top.
Right: Example of condenser use in a simple laboratory operation. A short-path distillation apparatus schematic , for purification of a low boiling liquid from higher boiling or non- volatile impurities. Shown in a cutaway view, red and blue indicating heating and cooling for example, circulating cooling water in blue. An exploded view, insofar as flasks 1 and 6 are shown disattached where trapezoids represent matching ground glass joints allowing tight seals of apparatus parts.
Impure liquid is placed in boiling flask 1, and heated with stirring or other assistance to boiling to prevent bumping see text. Vapor rises diagonally to the right, coming in contact with a cold finger type of condenser, 2, chilled by fluid flow through ports 3 and 4. As warm gaseous material boiled from flask 1 comes in contact with cold surface of condenser 2, the gaseous material changes state to liquid condenses , and falls, guided by the offset, pointed tip of the cold finger, to the right, through a funneled tip into collection flask 6, which is correspondingly cooled, to prevent any loss of product through adventitious heating and evaporation.
After the distillation is completed often not to complete dryness of 1 , the apparatus can be disassembled and a rough yield determined by weight of flask and contents, followed by analysis such as NMR or LC-MS to confirm identity and purity of the product.
Note, if the distillation is at ambient normal pressure, port 5 is attached to a drying tube a tube open to air, packed with a desiccant ; if it is a vacuum distillation , port 5 allows attachment of the vacuum pump.
