The invention relates to an evaporator comprising an evaporator body (3) surrounded by an evaporator housing (5), wherein the evaporator housing (5) is provided with a feed line (1) for feeding a liquid into the evaporator housing (5) and with an outlet (6) for emitting any vapour produced, wherein the evaporator body (3) comprises a multiplicity of plates (7) which are arranged in a planar manner one above another, wherein a void (8) is formed in each case between adjacent plates (7), wherein each of the voids (8) is fluidically connected to the outlet, wherein a liquid distributor is interconnected between the feed line (1) and the evaporator body (3), wherein the liquid distributor branches off from the feed line (1) in the direction of the evaporator body (3) in at least two distributor lines (VR), and wherein each distributor line (VR) is connected to at least one void (8).

The invention discloses a glass lined metal micro-reactor with enhanced heat transfer efficiency in continuous flow operation. More particularly, the invention discloses a glass lined micro-reactor that can be reassembled. The invention provides a novel glass lined metal micro-reactor with micro fluidic channels that provide a better mixing, better heat exchange, and better temperature control. The micro fluidic channels machined in the glass lined metal reactor/mixer may be straight, curved, lamellar, flower shaped, or spiral such that the cross sectional area of the micro fluidic channel is configured to suit the cross sectional area of the micro-reactor.

A micro-reactor system assembly comprises a stack of at least n process modules (1-6), wherein n is an integer equal to or greater than 1, made from a rigid first material and comprising at least one reactive fluid passage (1A, 1B, 2A, 3A, 6A) for accommodating and guiding a reactive fluid, and at least n+1 heat exchange modules (7, 8) made from a ductile second material other than said first material and comprising at least one heat exchange fluid passage (7A, 8A) for accommodating and guiding a heat exchange fluid, wherein each process module (1-6) is sandwiched between two adjacent heat exchange modules (7, 8).

The disclosure relates to microchemical (or microfluidic) apparatus as well as related methods for making the same. The methods generally include partial sintering of sintering powder (e.g., binderless or otherwise free-flowing sintering powder) that encloses a fugitive phase material having a shape corresponding to a desired cavity structure in the formed apparatus. Partial sintering removes the fugitive phase and produces a porous compact, which can then be machined if desired and then further fully sintered to form the final apparatus. The process can produce apparatus with small, controllable cavities shaped as desired for various microchemical or microfluidic unit operations, with a generally smooth interior cavity finish, and with materials (e.g., ceramics) able to withstand harsh environments for such unit operations.

An embodiment of a chemical synthesis device according to the invention includes a substrate provided with a first channel in which a plurality of fluids are subjected to a chemical synthesis and a second channel for controlling a temperature of the fluids flowing through the first channel.

A microfluidic assembly includes a planar microfluidic separation device and a support body configured to receive the planar microfluidic separation device therein. The support body is configured to apply a substantially distributed compressive preload to a substrate of the planar microfluidic separation device. The compressive preload applied to the planar microfluidic separation device may increase the achievable operating pressure of the planar microfluidic separation device.
