LAUDA process thermostats of the Kryoheater Selecta (KHS) series ensure high-performance temperature control at high energy efficiency and reliability. The compact device construction provides a long service life and maintenance friendliness.
Corresponding to the lowest working temperature, two-stage compressors (up to -60 °C) and/or cascade cooling systems (up to -90 °C) are used. The condenser is cooled by means of cooling water. The cooling capacity is controlled continuously and precisely by injection control. A step switch ensures energy-saving and low-wear partial load operation using an automatic compressor system. By means of the electric heating, Kryoheater Selecta can cover an operating temperature of up to 200 °C.

The 300 series fast GC is an unconventional gas chromatograph using directly heated columns for rapid heating and cool down. It is truly a fast GC with cycle times measure in seconds and not minutes. The system does not have an oven as in a conventional GC products because direct heating of the column eliminates the need for one.
The 300 Series fast GC is equipped with a split/splitless injector, EFC (Electronic Flow Control), 4-channel EPPC (Electronic Programmable Pressure Control), various detector options and boasts a small footprint of just 320mm x 370mm that makes it a valuable space saver. The columns are made by Restek of Silcosteel and are available in multiple phases and a wide range of dimensions.
A major bonus feature of the system is ACI (Automatic Column Installation) allowing for easy push button exchanges of columns. The column cartridge design allows the ACI feature to de-skill column changing and installation by removing the need for wrenches and column nuts. Simply place the column cartridge in position, press the column install button and let the install mechanism align and seal the column.

The 200 series autosampler has been designed for use with Ellutia's own award winning 200 series gas chromatograph. It has been designed to compliment the GC in both looks and price. With Up to 23 sample positions and up to 4 injections per vial selectable in the method setup the 205 series autosampler is more than suitable for overnight runs.
The 205 series autosampler can accept either 0.5,5 or 10 microliter syringes. The injection volume can be set to either 10, 20, 50 or 100% of the syringes volume when setting up a method. The 200 series autosampler comes with IPC (Intelligent Plunger Control) to allow for self calibration of zero volume for syringes. This system also monitors the plunger for any signs of resistance (if the syringe has become sticky) and warns the user so they syringe may be cleaned to avoid potential damage to the plunger.

The Thermal Energy Analyser (TEA) has been an industry standard for nitrosamine analysis since its introduction thanks to its incredible sensitivity and almost infinite selectivity for nitrogen containing compounds. The all new TEA 800 Series was designed with input from users of older model TEA's from the outset to ensure this new model delivered everything customers wanted. Thanks to this input the TEA is now smaller, easier to service and simpler to operate, whilst still retaining the same great analyticial performance as its predecessors.

Accurate and repeatable gas flow measurement is fundamental to obtaining good results from your gas chromatography. The traditional bubble flowmeter, relying as it does on the reaction time of the operator, is a potential source of error.
The Ellutia 6000 Series flowmeter eliminates this source of error and makes gas flow easement easier and more accurate. The flowmeter is calibrated as standard for the eight most common gases used in chromatography. In addition it also provides the following;
Split Flow rate - The column flow is measures followed by the flow through the split line. Simultaneous displays of column flow, split line flow and split ratio are displayed.
Linear Velocity - The user selects a column diameter from the list provided and then the linear velocity is calculated and displayed. The result is simultaneously displayed with the flow rate so that the operator can view them both and independently set either parameter.

Great for small groups or for students who are learning from home!
Grades 612. Investigate physical science and engineering concepts including buoyancy, displacement, and density. Students construct an aluminum foil boat prototype and measure how much weight their boat can carry before taking on water or sinking. Students are then challenged to think of ways to maximize the load the boat can hold using other materials to modify the design. Kit materials support a single student or a small group of students. Includes instructions.
