集多功能于一体的仪器
THT提供 µW 级灵敏度的微量反应量热仪uRC™和1.5ml一次性小瓶。该仪器可同时快速测定放热和吸热反应焓。通过计算机控制加样注射器可以对试剂进行高度精准的重复滴定。
The micro reaction calorimeter μRC from Thermal Hazard Technology (THT), performs isothermal, step-isothermal, temperature scanning and titration studies as well as having the capacity to stir liquid reaction media. Options for pressure measurement, solid addition and gas flow are available.
The small sample requirement (up to 1.5ml) permits rapid temperature changes because the relatively small heat sink reaches thermal equilibrium very quickly. A stable baseline and temperature change is typically achieved within 20 minutes. The μRC Peltier modules control the sample temperature over the temperature range of –20 to 170°C requiring no external chillers or liquid nitrogen cooling.
