Advanced Chamber
with Temperature and Humidity Control
P/N 100-26-TH

The Advanced Chamber 100-26-TH provides a controlled environment for up to 6" diameter samples. The chamber features rotating support, quartz windows for viewing, inlets for humid and dry air, outlets for exhaust and pressure relief. The temperature can be controlled up to 230° C or up to 85° C with humidity. The humidity level can be regulated between 0 and 100%. Gas parts are included as well as cooling ports to circulate water or a refrigerant through the base of the chamber to speed up cooling or to bring the chamber temperature to below ambient. The system ships complete with a controller, an ultrasonic humidification system for cool mist, and a dry air pump and desiccant-based drying unit. Additional customization is also possible with this versatile modular design. The Advanced Chamber is supported on Models 300 and 500 with or without the optional Tilting Base.

A temperature only version of this chamber is also available, p/n 100-25-T. It includes all of the same features as 100-26-TH except humidity control. The chamber temperature can be controlled up to 230° C and humidity can be added later with an available upgrade kit (p/n 100-26-H-KIT).

Automated Tilting Base
P/N 100-25-A

Advancing and receding contact angles are readily determined by inclining the substrate and allowing the drop to deform as a function of gravity. By mounting a ramé-hart goniometer on the optional Automated Tilting Base, it is possible to incline not only the substrate but the entire instrument, preserving the optics-to-specimen alignment. This technique greatly expedites such measurements. The Automated Tilting Base is fully software driven and is supported by DROPimage Advanced v2.3 and above. This option is supported by Models 250 and 500 or other systems that have been sufficiently upgraded.

Manual Tilting Base
P/N 100-25-M

This tilting base is the same as 100-25-A except instead of being software-driven, it's manually driven with a hand crank. The 100-25-M can be upgraded to the Automated version with the upgrade kit p/n 100-25-U. This option is supported on every current-generation ramé-hart instrument.

Automated Dispensing System
P/N 100-22

The ramé-hart Automated Dispensing System is a software-driven tool for producing precise pendant and sessile drops and is particularly useful for dynamic studies - such as advancing / receding studies. For more information, click here. This option is supported on Models 200 and up or older systems that have been sufficiently upgraded. Stand alone software is also available for use with other instruments.

Oscillator
P/N 100-28

The ramé-hart Oscillator, when used with the Automated Dispensing System, provides precision-controlled periodic oscillatory deformation of pendant and sessile drops and bubbles in order to measure surface dilatational elasticity and viscosity using DROPimage Advanced v2.4 or above. The Oscillator supports speeds between 0 and 25Hz and is ideally suited for many dynamic surface tension and surface rheology studies. For more information, click here.

Environmental Chamber
P/N 100-07

This option, in conjunction with any Model 100-00, 300, or 500 ramé-hart goniometer, permits controlled conditions for the study of contact angle, surface energy, and surface tension. Controlled elevated temperatures to 300 C are produced by the integral electrical heaters, while sub-ambient temperatures can be produced by circulating a suitable coolant through the base of the chamber. Fittings for this purpose, and others for atmosphere control, are furnished. The chamber is suitable for vacuum use and pressures to 0.6 Atmospheres. Custom designed environmental chambers are available by special request. This option requires a Proportional Temperature Controller (p/n 100-10) if regulated elevated temperature is desired.

Additionally, a quartz cell (p/n 100-07-50) is available for liquid/liquid, inverted sessile drop, and captive bubble studies. A Cover with Stage assembly (p/n 100-09-10, shown below) is also available to facilitate advanced studies requiring a submerged adjustable stage.

Proportional Temperature Controller
P/N 100-50

The ramé-hart Proportional Temperature Controller permits precisely regulated temperatures between ambient and 300° C and is used in conjunction with the ramé-hart Environmental Chamber p/n 100-07, Elevated Temperature Syringe p/n 100-11, and the ramé-hart High Pressure Chamber p/n 100-08. Available in 115V and 230V versions.

Chamber Cover with Stage
P/N 100-09-10

Replaces the standard cover supplied with Chamber 100-07. Contains an externally adjustable substrate stage and permits studies of sessile drops on either side of substrate (normal and inverted), or captive bubbles on the underside. Substrate clamping will also accommodate films. Cover is equipped with an O-ring seal to interface with Elevated Temperature Syringe 100-11.

Elevated Temperature Syringe
P/N 100-11

Functionally similar to the Micro-syringe Attachment 100-10, this unit permits forming drops of materials which have melting points as high as 230° C. May be used with Chamber 100-07 and Cover 100-09-10 for controlled environment studies. Test materials contact only glass and stainless steel. A Temperature Controller is included. This accessory is ideal for liquids with high melting points such as solder and polymers. One replaceable syringe assembly is included.

Film Clamps
P/N 100-15

The Film Clamps are furnished as a pair and mount directly to the working surface of the leveling stage of any ramé-hart goniometer. Their function is to maintain flatness of film-type substrates and they can also be utilized to secure specimens to the stage when using the tilting base to evaluate advancing and receding contact angles.

Immersible Film Stage
P/N 100-16 

This unit fits within the interior of our Environmental Chamber or Advanced Chamber, providing a convenient means of supporting small, film-type substrates. A screw-activated tensioning method is provided to eliminate ripples from the substrate.

Rotating Wafer Support
P/N 100-21-xx

The rotating support maintains flatness and position of 4", 6", 8", 10" and 12" wafers in order to achieve contamination-free contact angle readings. It incorporates a rotating stage plate with displacement holes creating the appropriate suction. The wafer support mounts directly to the stage of the Contact Angle Goniometer. Requirements for larger wafer supports can be accommodated. Models 100-00, 300, and 500 support all sizes of rotating wafer. Model 400 supports and includes an 8" wafer support (and other sizes can be included). The Standard Goniometer supports the 4" wafer support only. Check current product matrix for detailed specifications.
