Product Details:
  • This is a reactor system specially designed to perform batch enzyme reaction utilizing the glucose isomerisation reaction catalyze by glucose isomerase.
  • The unit is used to demonstrate batch enzyme kinetics and enzyme characteristics.
  • The reactors use the saponification reaction between ethyl acetate and sodium hydroxide.
  • This provides a well understood and safe reaction for the students to investigate the different reactor types.
  • Developed a set of algorithms which link the degree of conversions of the reactants to the electrical conductivity of the product.
  • In this way the progress of the reaction can be monitored in real time, without the inconvenience and innaccuracy of titration methods.
  • The fourth reactor - stirred tank reactor in series - is mounted on a dedicated unit.

The set up consists of a glass column packed with Rasching rings. Liquid is fed at the top of the column through distributor. The solute gas and air are measured separately, mixed in a mixing chamber and then passed through the packed column vertically upward and absorbed in liquid. All the flow rates can be independently varied to simulate different conditions. Liquid sample can be taken out from the sampling point at the bottom of the column for analysis.


Technical Data:

  • Column: Borosilicate Glass Dia. 55 mm
  • Length 750 mm (approx.)
  • Packing: Borosilicate Glass Rasching Ring

In the process of gas absorption, a mixture of gases is contacted with a liquid, for the purpose of dissolving one or more components of the gas and to provide a solution of them into the liquid. In it, a gas phase consisting of CO2 and air is introduced into the bottom of the packed column. Adjustment of their flow ratio is obtained by manual valves. A sample of the gas mixture is sent to a CO2 concentration sensor located inside the electric console, and readings of flows and CO2 percentage concentration are seen on the display. For the liquid phase, water (or a solution of sodium hydroxide) is pumped to the top of the column where it falls through the packing material. The contact of the two phases is in counter-current operation and enhances the mixing and diffusion of CO2 in the liquid phase at the conditions of room temperature and atmospheric pressure.

 

Technical Data:

  • An apparatus for teaching the principles of the absorption of gas into liquid, using a packed column
  • Column working length is 1.4m x 80mm diameter, split into two sections
  • Two electronic pressure sensors measure the pressure drop across each half of the column
  • An electronically controlled submersible pump provides a liquid flow of 1-10 l/min
  • 60l feed tank
  • Water flow can be used in either recycle or one-pass operation
  • Column supplied with 10mm x 10mm Raschig rings as packing material, total volume 7l. Other sizes can be used
  • Centrifugal fan provides air flow up to 160 l/min
  • Two electronic temperature sensors measure the air and liquid temperatures

It consists of a benchtop unit onto which are mounted two 250mm long, 10mm diameter borosilicate glass chromatography columns. Both are equipped with adjustable end pieces to allow different bed heights to be investigated. On the top of each column are septum injectors to allow introduction of a sample onto the column surface. The columns are fed by a three-channel peristaltic pump of an eight-roller design in order to give smooth flow. The pump has variable-speed drive and a wide range of tube bores can be used thus giving a very wide flow-rate range. Switching valves allow the operator to easily select the desired column for operation. A bubble trap is fitted before the inlet to the columns to prevent air from entering. The outlet from the column passes to a UV optical flow cell for online measurement of sample elution. Liquid exiting the flow cell can either be led to drain or collected using the fraction collector. The fraction collector, which has capacity for 48 3ml test tubes, is timer controlled.


Technical Data:

  • A benchtop unit comprising a vacuum-formed ABS plastic plinth with integral electrical console
  • Two borosilicate glass chromatography columns (250mm long and 10mm internal diameter) fitted with septum injectors and fed by a 3-channel peristaltic pump
  • Syringe and needles for sample injection
  • Fraction collector
  • Analysis using a UV optical flow cell
  • Protection devices for all electrical circuits
  • Two displays: Optical absorbance, timer display for fraction collector
  • Sensor signals are routed to the USB port for connection to a PC
  • Comprehensive instruction manual with detailed procedures and laboratory teaching exercises
