E-Z Press 12, 15, 20 Ton Hydraulic Laboratory Presses ICL’s new patented E-Z Press hydraulic lab presses feature a unique lightweight ergonomic design. All E-Z Press laboratory press models weigh less than 90 pounds due to ICL’s patented unibody construction. The 12 ton E-Z Press laboratory press weighs a mere 51 pounds! The 15 and 20 ton E-Z Press will handle a variety of lab applications, including pressing KBr pellets for FTIR spectroscopy and briquetting samples for XRF spectroscopy. Ports in the walls of the lab press frame allow access for vacuum lines and electrical cords to the area between the platens, which enables use of the press with evacuable dies and heated platens. The 15 and 20 ton E-Z Press can also be used for making thin films with ICL’s Precision Thickness Film Maker and Heated Platens. Automated versions or our laboratory presses are available (see Air-EZ) which are driven by pneumatic motors powered by your lab’s compressed air supply.
The newest additions to the E-Z Press laboratory press line are ICL’s new 1 and 2 ton E-Z Presses. The 1 and 2 ton units offer sensitivity at low pressure levels in applications where precise control of the load on the sample is required, such as pressing pellets of intrinsic pharmaceutical ingredients for dissolution rate analysis.
All E-Z Presses lab presses feature built in polycarbonate safety shields with solid brass hardware. There are die centering depressions in the round bottom platens. Each press comes with a standard stainless steel filling disc to flatten the platen. The bottom platen of the 2 and 12 ton E-Z Press automatically centers ICL’s 13mm Macro-Micro die. The bottom platen of the 15 and 20 ton E-Z Press has a 4" diameter depression and optional donut shaped inserts are available to automatically center ICL’s 13mm, 20mm, 32mm, 35mm and 40mm die sets. Optional extra long handles are also available for all presses for extra leverage.

E-Z Press 1 and 2 Ton Laboratory Presses ICL's 1 & 2 Ton E-Z Presses feature a unique laboratory press design combined with the same unibody construction and other features common to our E-Z Press line. We have redesigned these laboratory presses to maximize the sensitivity of the press for exact reproducibility of applied force. Normally, hydraulic lab presses use a pump to apply pressure to the piston of the hydraulic cylinder. The hydraulic fluid pump found in standard lab press designs increases the pressure of the hydraulic fluid in spurts which causes the force being applied by the press to jump in increments which are difficult to control with precision. In addition, there is some backflow of hydraulic fluid during the pumping process which amplifies the lack of reproducibility of force levels.
Many applications for low pressure laboratory presses such as intrinsic ingredients dissolution analysis require the application of highly reproducible force levels, and 12 ton hydraulic presses are inherently unsuited to these applications. By removing the pump and sealing the hydraulic cylinder, we have created a press which enables application of very small increments of force levels which can be reproduced with a high degree of precision from sample to sample and without pressure drops. The force is applied to the sealed cylinder by turning the lead screw assembly against the platen on which the die is seated, similar to the manner that a wine press operates. Since the force levels are very low, very little effort is required to turn the lead screw. These lab presses are equipped with clamps which allow them to be anchored to any bench top and easily moved to different locations within the lab and they can also be bolted to a lab bench using the fixtures provided with the press. When used with ICL's intrinsic dissolution analysis dies or ICL's Macro-Micro dies, the dies are automatically centered in the press. Note that special short profile Macro-Micro dies are required for this press. The 1 and 2 Ton E-Z Press can also be used with ICL's 2mm, 4mm and 7mm die sets and die centering inserts are available for the smaller die sets. Also available in high profile version for applications such as Wood apparatus intrinsic dissolution testing.
Air-EZ Air Powered 15 and 20 Ton Laboratory Presses The Air-EZ laboratory press, adds automation to the patented unibody design that enables ICL to make the E-Z Press so light and ergonomic. The press is driven by an elegant and quiet pneumatic motor that runs off of your lab’s compressed air supply or most commercially available air compressors. No physical effort whatsoever is required. The press jacks up to its rated capacity of 15 or 20 tons in a mere 5 seconds. Ports in the walls of the press frame allow access for vacuum lines and electrical cords to the area between the platens, which enables use of the press with evacuable dies or heated platens. The Air-EZ lab press is suitable for many lab applications, including KBr pellets and XRF briquettes. It has a footprint that is less than one foot square and weighs only 130 pounds. If you dread pumping up a manual press or crave lab space, this is the solution. Higher tonnage versions are available and the press is available with heated platens and our Precision Thickness Film Maker as a Film Maker Kit. The 15 and 20 ton Air-EZ laboratory presses feature built in polycarbonate safety shields with polished brass hardware and a die centering depression in the round stainless steel bottom platen (see Fig. 1). The press comes with a standard 4" diameter stainless steel filling disc to flatten the platen (see Fig. 2). Optional donut shaped inserts are available to automatically center die sets with a variety of base diameters.

Sealed Liquid Spectrophotometer Cells - Model SL-4 Heavy Duty ICL offers a heavy duty, corrosion resistant sealed liquid spectrophotometer cell designed to withstand rough handling and continuous sampling in laboratories. The large 25mm circular aperture is suitable for use with both dispersive and FTIR instruments. Each spectrophotometer cell is machined individually from 1/4 inch thick stainless steel. Pathlengths can be nominal or calibrated to 4 decimal places (eg. 1.0152mm) and spectrophotometer cell pathlengths can be matched within ±3% for interchangability. All optical materials are available in standard nominal pathlengths ranging from 0.015mm to 1mm. Other pathlengths are also available. The window is a 39.5mm x 39.5mm x 6.5mm hexagon. ICL also offers an infrared cell reconditioning service in Section 0010 and a calibration service for all spectrophotometer cells. Pathlengths can be nominal or calibrated to 4 decimal places (eg. 1.0152mm) and cell pathlengths can be matched within ±3% for interchangability. ICL also offers an infared cell reconditioning service.
Press-N-Lok Demountable Cell ICL’s Pres-N-Lok Cell enables the user to analyze mulls and smears without the use of clumsy springs, nuts, and bolts. The cell is assembled by placing the sample on one (1) of two (2) 25mm x 4mm crystal windows separated by a PTFE spacer, dropping them into the bore of the inner barrel, and pressing in the outer barrel. The cell consists of a back plate of anodized aluminum, a self locking inner barrel with a Viton O-ring over which the outer barrel slips on and off with ease, and assorted PTFE spacers.
Heated Vapor Gas Multi-Sampler This heated cell can be configured as a gas cell (Fig. 2) or for vaporizing samples that are normally solids or liquids at room temperature. Configured for gas sampling, the cell incorporates 2 valves, an inlet and an outlet, that enable flowing gas samples through the cell. In its solid and liquid vaporization configuration, the cell has an outlet needle valve from which a vacuum can be pulled and two (2) sample inlets. One inlet is a needle septa injection port on the top of the cell which is similar to the type used in gas chromatography. There is a second inlet in the form of a side port for inserting solid samples, which also doubles as the thermocouple port. Using the side port eliminates the need to recheck vacuum seals whenever the cell is opened to insert solid samples. The 250w heating jacket extends over the end of the cell so that both the cell body and the optics are heated, and allows operation at temperatures up to 200°C. Condensation on the optics is minimized by heating them to the same temperature as the sample chamber. A type J iron constantan thermocouple is provided with plugs which are compatible with the optional temperature controller. The cell body is type 304 stainless steel and an assortment of seals is provided - silicon rubber, viton and PTFE.
Cells are factory pretested for vacuum leaks using dummy windows and then new windows are shipped with the cell. The cell comes standard with 47 x 6mm KCl windows. The clear aperture is 39mm. Other window materials are available. Requires either a cell mount (0008-5162) (Fig. 1) or base plate mount (0008-9405) (Fig. 2). An optional high stability temperature controller is available. The temperature controller (see description) has ramp and soak cycles that can be programmed on the keypad.
