Environmental chambers

With different environmental chambers, temperatures from -30 °C to 700 °C can be set. All temperature chambers feature three windows made of special optical glass, a set of two Pt100 temperature sensors, and an inert gas inlet. Also included are special cover plates in order to optimize the needle entry gap.

Liquid Temperature Control Unit TFC 100Pro

The liquid temperature control unit TFC 100Pro is used in conjunction with a liquid circulator bath. The TFC 100Pro features:

• temperatures between -10 °C and 100 °C
• temperature reading module TRM 100 for temperature measurements with contact angle meters of the OCA series
• prepared for connection to humidity generator HGC 20/30
• optional triple diffusor TDI 100 to prevent condensation at the windows while working below room temperature by using a dry gas flow

Peltier Temperature Control Unit TPC 160U

The Peltier temperature control unit TPC 160U utilizes an electric Peltier system for temperature control. The TPC 160U requires a liquid counter cooling and features:

• temperatures between -30 °C and 160 °C
• TC-U PID controller for temperature setting
• prepared for connection to humidity generator HGC 20/30
• optional triple diffusor TDI 160 to prevent condensation at the windows while working below room temperature by using a dry gas flow

TEC 400U and TEC 700U

The electrical temperature control units TEC 400U and TEC 700U use electrical resistance heating of the chamber floor and lid. The TEC 400U and TEC 700U feature:

• temperatures from room temperature to 400 °C or 700 °C, respectively
• one / two TC-U PID controller for temperature setting
• connector for optional counter cooling with pressurized gas

Heated dosing systems

Where a liquid has to reach a defined temperature, the syringe and the dosing needle can be heated independently of the sample environment.

Syringe heating device SHD

With the syringe heating device SHD, a syringe inside the electronic syringe module ESr can be heated using a liquid circulator bath. Hence, the temperature of the syringes can be controlled between -10 °C and 90 °C.

The SHD consists of a heating jacket for easy mounting and demounting of syringes and a Pt100 temperature sensor.

Electrical needle heating devices NHD

Dedicated to investigating the properties of metals, polymers or hot melts in their liquid state are the electrical needle heating devices NHD 400U and NHD 700U. This special piece of development enables the dosing of molten solids at temperatures up to 400 °C or 700 °C, respectively.

The NHD 400U and NHD 700U feature:

• temperatures from room temperature to 400 °C or 700 °C, respectively
• cannula heater with integrated temperature sensor
• ceramic cannula with plunger
• option for glass syringes with NHD 400U available
• heating carrier with fine adjustment screws for the axial and horizontal cannula positioning
• TC-U PID controller for temperature setting

Systems for special environmental conditions

For measurements under extreme ambient conditions, the contact angle meters of the OCA series can be equipped with a high temperature furnace or a high pressure measuring system.

High temperature furnace HTV 1800

Inside the high temperature furnace HTV 1800 from DataPhysics Instruments, contact angle measurements at up to 1800 °C and under vacuum down to 10^-5 mbar, or inert gas atmosphere, are possible. The high temperature furnace HTV 1800 is available as part of an OCA 25 special model.
