Sigma Borosil glass 3.3 pipeline components are widely used in chemical, pharmaceutical, dyes & allied industries and food & drink production where the advantages of using glass as a basis for the construction of complete process systems have long been recognized. The main reasons for wide acceptance of Sigma borosilicate glass 3.3 are because of (a) Universal resistance to almost all chemicals resulting in reduced contamination risk, (b) Transparency for ease of visual monitoring of the process (c) Smooth surface allows easy cleaning & sterilization of systems. This guarantees long service life & minimum maintenance requirements.

A rotary evaporator is a device used in Chemical Laboratories for efficient and gentle removal of solvents from samples by evaporation.The motor unit which rotates the evaporation flask containing sample material.A vapour duct which acts as an axis for sample rotation, and a vacuum tight conduit for the vapour being drawn off of the sample.A vacuum system (not integral part of the equipment) to substantially reduce the pressure within the evaporator system.

• FeatureMaximum Evaporation in Single Pass

This technology gives the ability to remove volatile components from less volatile materials that are heat – sensitive, viscous, foaming, or contain solids. It offers short residence time, thin film formation by the centrifugal force of the rotating wiper system, the speed of which, can be adjusted to the viscosity of the product to be evaporated, which increase the evaporation efficiency. This is possible by the creation of the uniform film on the smooth heated surface of the glass body.

This unit is typically used for only distillation and fractionation under vacuum or at atmospheric pressure. The typical unit has distillation vessel fitted with a metal heating cooling bath and with a packed column above reflux divider and coil condensers below are fitted on the packed column. Condensed material is either taken back to the vessel or to the receiver via product cooler.

Hydrogen Chloride gas produced as a by product can be economically processed into Hydro – Chloric Acid by simple Absorption Adiabatic Absorption is the most effective means of production of Hydro – Chloric Acid solution. Under normal operating conditions Hydro Chloric Acid Solution of 30% – 31% strength can be obtained.These absorbers operate, as the name implies, without any heat input into the reaction zone.The gas loading should in no case fall below 50% of the design maximum for adiabatic absorption column to be most effective means of absorption.
