Catalytic Reactors |
ALPHA CHEM-1327 Catalytic Reactors A benchtop unit comprising a vacuum formed ABS plastic plinth with integral electrical console on to which is mounted the packed bed reactor columns, feed pump, optical sensor and optional Flow Injection Analysis (FIA) system. The unit is supplied as standard with two reactor columns for chemical catalysis. A third column can be optionally added to the system for biological (enzymic) catalysis. A heated water supply to the column jackets allows automatic control of reaction temperature to a set point value. Feed flow rate can be varied between 0 and 15 ml/min. The FIA pump can be adjusted to give flow rates up to 2.5 ml/min. All electrical circuits are fitted with appropriate protection devices. The console has two digital meters. The first, associated with the controller, shows the temperature of water supplied to the column jackets, and the second shows the optical sensor reading which provides a measure of product concentration. Corresponding signals are routed to the I/O port for connection to a PC.Description: The introduces students to the fundamentals of packed bed catalytic reactors. It is a benchtop unit available with either two or three reactor columns. Using two columns with a chemical catalyst allows a different particle size exchange resin to be used in order to study the effect of particle size on reactor kinetics. It is possible to use a third column to investigate biological catalysis, using the enzyme invertase, and compare this with chemical catalysis. An optional flow injection analysis (FIA) module is available. This module is positioned on the CEU plinth and provides an easy on-line measurement of product yield, eliminating the need for manual assays. |

ALPHA CHEM-1309 Aerobic Digester
ALPHA CHEM-1309 Aerobic Digester Aerobic Digester consists of a 2 gallon reactor vessel mounted on a steel base, with a liquid feed pump, air supply, and instrumentation for monitoring and controlling the process. The cylindrical wall of the reactor is made from 2 layers of porous plastic material to retain the suspended solids, while allowing treated water to pass through to the outer, annular exit chamber. This design allows the essential features of the aerobic treatment process to be studied without the distractions of having to settle the solids adequately enough for external recycle, a well known laboratory problem. The porous liners are removable for cleaning, and a spare liner is supplied. Waste water is drawn from a feed tank by a 120V motor driven peristaltic pump. Flow rate is controlled by a variabe run time control that determines the minutes of run time within a 10 minute cycle. The pump delivers the feed to the reactor vessel through a transparent lid. Air is supplied at a measured rate by a small air pump, and discharges into the base of the reactor via an air distribution device. This provides the necessary oxygen for the digestion process, as well as produces sufficient bubbling for stirring and reaction. The liquid level in the reactor is maintained at a constant value of 1 or 2 gal. by an overflow device connected to the outer annular chamber of the vessel. Discharge is by gravity to a floor-standing product tank (not supplied).
The reactor temperature is maintained by a 3-term PID controller which varies power to an immersion heater within the vessel. Any temperature between ambient and 95F may be selected, with the best conditions being a few degrees above the diurnal maximum in the users laboratory. Dissolved oxygen and pH probes and meters are included. The reactor lid contains a gas exit port, suitable for sampling the gases for subsequent analysis Specifications : Feed pump 120V, peristaltic, 10 rpm, variable run time control corresponding to 013 gal. per day Air pump 240V/120V, 01.35 gpm Reactor vessel 2 gal. maxium capacity pH meter Range 0.00 to 14.00 Dissolved oxygen meter Range 0100% saturation, resolution 2% Reactor heate Electrical immersion 250W Temperature controller 3-term PID, temperature limit set at 95F |

Alpha Chem is manufactures, exporter & suppliersAir Shower. Air shower is an enclosed chamber where clean air Jets Shower at the person/material at velocity between 6000 to 8000FPM and remove contaminants entry and exit. Doors are locked condition during shower cycle and are interlocked at other times Air Showers are self contained chambers installed at entrances to cleanrooms and other controlled environments. They minimize particulate matter entering or exiting the clean space. Personnel and materials entering or exiting the controlled environment are scrubbed by high velocity HEPA-filtered air jets with velocities of 20-22m/s (4000-4300fpm). Contaminated air is then drawn through the base within the unit, filtered and recirculated. Cleanroom Applications: The greatest source of particulate contamination in a cleanroom is the operator . Air showers are installed between change areas and the cleanroom. The air shower enhances cleanroom operating protocol by serving as a reminder to all operators that they are entering a controlled environment. Personnel therefore develop the habit of gowning up properly before entering the air shower .
