-190 to 250C Liquid, Solid, Gas Cell

-190 to 250C Liquid, Solid, Gas Cell
This is a -190 to 250C Variable Temperature Cell which permits transmission mode measurement of solid and liquid samples with gas exchange capabilities across the face of a solid sample. The cell consists of a vacuum outer jacket and a cold finger that may be cooled with liquid refrigerant. Sample cells are inserted into a block attached to the cold finger fitted with heaters to maintain precise temperature control. The external vacuum jacket windows are heated to prevent condensation at sub-ambient temperatures. The sealed or demountable liquid cell asssembly can be converted to a flow cell configuration with the appropriate attachment. Two fixed thermocouples are installed to monitor the temperature of the cell holder and the outer jacket window assembly. A spare thermocouple can be introduced to accurately monitor the sample temperature. The cell can be configured for UV-Vis and Fluorescence applications.

Options available include liquid sealed and demountable cell configurations, solids cell, flow through cells, and a variety of window materials to assemble within these cells. Scroll below for impression and order details.

High pressure cells are available for liquid and gas samples analysis under high pressure (2000 psi and 5000 psi options). The useful temperature range for the high pressure cells is from -15C to 180C. The cells are fabricated from Stainless Steel for chemical resistance and durability with two 1/16 Stainless Steel flow tubes brazed to the cell body. A choice of fixed pathlengths include 0.5, 1.0, 2.0, 5.0 or 10mm. The transmission windows are permanently sealed in the cell housing using perfluoroelastomer o-rings. Available optical materials include UV Quartz, Sapphire and Zinc Selenide.

The high pressure cells can be used at ambient temperature when mounted on the standard 3" x 2" backplate. For heated or sub-ambient applications, the cells listed below can also be used with the 250C Solid and Liquid Cell and the Transmission Cell Heating/Cooling Jacket.

Additional options represent a choice of temperature controllers for 110V or 220V operation with or without an RS-232, USB or RS-485 computer interface.

Solids Cell Holder
Solids Cell Holder
REFLEX Analytical offers a solids cell holder for use with the Variable Temperature Cell. Part number 20610 consists of outer and inner cell threaded bodies and three pairs of pressure plates. The varying aperture sizes of the pressure plates enable samples with a diameter of 12 - 17mm, 17 - 22mm and 22 - 30mm and up to 8mm thick to be analyzed. A T-type Cu/CuNi thermocouple can be inserted in the cell's thermocouple port to monitor sample temperatures. The solids cell holder can operate without transmission windows if desired.

Liquid Transmission Cells
Liquid Transmission Cells
REFLEX Analytical offers sealed and demountable liquid cells for use with the Variable Temperature Cell. Each version is supplied as a completely assembled cell with windows and a spacer at the pathlength of your choice. Sealed cells have a lead spacer and lead top gasket and all components are permanently amalgamated together. Demountable cells have a teflon spacer and teflon top gasket and as such allow for windows and spacer pathlengths to be interchangeable.

Each static version stainless steel cell assembly provides for a 25 x 10mm clear aperture and includes a front plate with inlet/outlet plugs and thermocouple port, a back plate, front gasket, rear gasket, threaded luer fitting, flushing tube, syringe needle, (2) teflon washers, a 3/23" Allen key, lead or teflon spacer (specify 0.025mm, 0.05mm, 0.1mm, 0.2mm, 0.5mm or 1.0mm) and a choice of transmission window materials. The transmission materials available include but are not limited to NaCl Sodium Chloride, KBr Potassium Bromide, CaF2 Calcium Fluoride, BaF2 Barium Fluoride, and ZnSe Zinc Selenide. A T-type Cu/CuNi thermocouple can be inserted in the cell's thermocouple port to monitor sample temperatures.

Optional flow through cells have an alternative front plate with 1/16" o.d. stainless steel tubing brazed to the sample port positions. The flow tubes are assembled with Swagelok connection fittings such that other liquid delivery type tubing can be connected to the cell front plate. It is recommended that this flow kit plate is supplied attached to the sealed cells. In this fashion, the flow plate is sealed to the front lead gasket and sealed window assembly. The threaded luer and flushing tube cannot be attached to the flow cell front plate.
