TT DMA ACCESSORIES
1 litre Super Cryo
The 1L Dewar is used for cryogenic cooling in conjunction with the range of Triton DMA equipment. It is of robust design with added safety features and a convenient lever shut off valve.
The thermally efficient design of Triton DMAs make a 1L dewar suitable for virtually all sub ambient experiments. 1L of liquid nitrogen can typically run 1 sample to -190°C or 6 samples to -100°C.
| Coolant Consumption | Safety Features |
| -100°C | 3 minutes | 0.125L Liquid N2 | Presssure relief valve fitted as standard |
| -150°C | 5 minutes | <.5L Liquid N2 | Phase seperator on outlet |
| -190°C | 7 minutes | <1L Liquid N2 | Liquid nitrogen handling safety instructions |
30 litre Auto Cryo
The 30L Dewar is used for cryogenic cooling in conjunction with the range of Triton DMA equipment. It is of robust design with added safety features and an automated approach to liquid nitrogen management.
Although the 30L Dewar has a longer equilibration time than the 1L Dewar, once pressurised, it will provide continuous use of the DMA over the full range of sub ambient temperatures for multiple samples.
The 30L Dewar comes with an Auto Cryo Kit to deliver cooling in a precise and controlled manner.
| Coolant Consumption | Safety Features |
| -100°C | 3 minutes | 0.125L Liquid N2 | Presssure relief valve fitted as standard |
| -150°C | 5 minutes | <.5L Liquid N2 | Phase seperator on outlet |
| -190°C | 7 minutes | <1L Liquid N2 | Liquid nitrogen handling safety instructions |
Immersion Accessory
The Triton Technology Fluid Bath is an accessory for the range of Triton Technology DMA equipment. The fluid bath enables a sample to be immersed in a solvent or media whilst the TTDMA experiment is being performed.
The immersion fluid can be temperature controlled using a
circulating fluid from a separate circulation bath.
Ports are provided to allow circulation of:
- Gas (such as nitrogen or air)
- Humidity controlled environment (when used with the humidity generator and controller)
- Cryogenic fluid (such as liquid nitrogen)
Temperature Range: Ambient to 150°C (dependant on immersion fluid used)
Immersion Bath Material: Anodised Aluminium supplied as standard
85/85 Humidity Chamber
The Triton Technology 85/85 Humidity Chamber is a unique solution to deliver an accurate relative humidity up to 85°C and up to 85% humidity in a TT DMA.
This Chamber also requires the Triton Humidity Generator and Controller and a Recirculator.
Features
- Thermal jacket completely surrounds sample chamber
- Easy conversion to standard DMA use and vice versa
- Utilises the proven feedback control of the Triton Humidity Generator and Controller unit (humidity sensor incorporated inside the Chamber)
Benefits
- No ‘cold spots’
- Highly stable humidity control
- Rapid set up
| Humidity Range | 5% to 95% (25°C) 10% to 85% (85°C) |
| Temperature Range | 5°C to 85°C |
| Sample chamber volume | 200 cc (Approx) |
| Connections | Heated humidity transfer line Humidity sensor connection In and out Recirculation fluid connections |
Circulator for Humidity Chamber and/or Immersion accessory
When running the Triton Technology DMA, it is necessary to control the temperature of the sample environment. This is normally done by using the in-built electrical heating option in the furnace coupled with liquid nitrogen for cooling. By using these features alone or in conjunction with each other, good temperature control can often be achieved.
For some applications, however, it is necessary to have more stable temperature conditions. The circulator, supplied by Triton Technology, provides this very stable environment and is predominantly used in conjunction with the Fluid Bath and Humidity Controller where very precise temperature control is required.
The bath and temperature controller are manufactured by Grant Instruments Ltd. The final Circulator product that Triton Technology supply has been modified with quick release fittings and plumbing to attach directly onto either the Fluid Bath or the DMA furnace. The temperature range allows for the majority of both immersion and humidity controlled experiments.
