For many years ramé-hart has offered a
variety of special purpose chambers for use with its goniometers. These include an
Environmental Chamber with optional Temperature Control, a High Pressure
Chamber, an Environmental Chamber with Humidity, Environmental Chamber
with Wafer Support and many custom
chambers. These chambers allow researchers to control the temperature,
and other environmental conditions in order to replicate real world
and specific controlled conditions, increase reproducibility, and study the effects temperature,
pressure, humidity, and different gas phases have on the contact angle, surface energy, and
surface tension of their test specimens.
Recently we have built a new Advanced Chamber which is available in two versions. The first, Advanced Chamber with Temperature and Humidity, p/n 100-26-TH, replaces our former Environmental Chamber with Humidity p/n 100-07H. And the second, Advanced Chamber with Temperature, p/n 100-26-T, is the same chamber but provides only temperature control. The new Advanced Chamber is modular allowing us to customize the design and adapt it to the needs of our customers. Unlike the prior chamber which had a unibody design, our new Advanced Chamber is constructed from 8 panels which can be interchanged and customized for special requirements. The standard layout provides 6" diameter rotating specimen support, leveling base, gas ports, cooling ports, (2) thermocouple ports, (2) quartz windows, inlets for dry air and wet air, outlets for exhaust and pressure relief, a housing for the humidity probe, and an electrical interface for the heaters. The TH version includes an ultrasonic humidifier and humidity and temperature controller with 0-100% humidity and ambient to 85° C temperature control. When humidity is disabled, the temperature can be controlled to 230° C. The H version includes a 0-230° C temperature only controller. We also have an upgrade kit, p/n 100-26-H-KIT, which will upgrade the T to TH.
The chamber can also be used with our quartz cell for performing liquid/liquid and captive bubble studies in a controlled environment. Dispensing is done by needle with either our microsyringe assembly or Automated Dispensing System. The lid can be modified for special drop disposition requirements.
If you have any questions or would like
a quotation for either the 100-26-TH or 100-26-H, please contact us.
