Specifications on MicroTroughXS / MicroTroughXL
Physical dimensions
| Base mechanics | 33 x 14 x 6 (h) cm ( 13 x 5.5 x 2.4 inches) |
| Electronics | 27 x 23 x 8 cm (10.6 x 9 x 3.1 inches) |
| Total weight | 3.55 kg (7.8 lbs) |
| Acrylic casing | Prevents perturbation of the film by air flow and accumulation of dust into the interface. Allows for the use of protecting gas to reduce oxidation and photobleaching in fluorescence microscopy and spectroscopy. |
| MicroTroughXS | Standard trough, outer base plate dimensions 33 x 14 cm (13 x 5,5 inches) |
| MicroTroughXL | Extended (Precision Plus) trough, outer base plate dimensions 51,6 x 19 cm (20,3 x 7,5 inches) |
Control of film area
| Barriers | Made of hydrophilic, inert polymer (Delrin). Also hydrophobic barriers made of PTFE are available upon request. |
| Compression velocity | Can be freely varied between 1 and 200 mm/min (one barrier |
| Inaccuracy | Less than 0.1 % |
| Barrier motion | High precision microstepping motor guarantees extremely precise and smooth control of area |
| Software | All measurements are computer controlled, with continuous, real-time display of retrieved data |
Measurements of surface area
| Principle | Wilhelmy method using a small diameter ( 0.51 mm) special alloy wire. No artefactual hysteresis as when using the conventional Pt-plates. No drying and accumulation of salt which cause significant errors when filter paper is used. |
| Dynamic range | 0 to 130 mN/m |
| Atmospheric control | Acrylic enclosure and purging with protecting gas (argon, nitrogen) prevents oxidation of the film and minimizes photobleaching in microscopy and spectroscopy, while allowing continuous monitoring of surface pressure. |
| Resolution | 10 µN/m |
| Temperature sensor | Automatic monitoring and display of temperature in the course of the experiment. Resolution 0.1 degrees. |
Troughs
| Material | Metal alloy and high purity PTFE. Several designs available. Also user-defined designs are routinely made. |
| Volume | 300 µl in surface pressure measurements (Multiwell plate). 22 ml (XS) / 45 ml (XL) in Langmuir-troughs, and 55 ml (XS) / 100 ml (XL) in Langmuir-Blodgett troughs. Subphase can be magnetically stirred. |
| MicroTroughXS | Standard trough, inner area 23 x 5,9 cm (9,1 x 2,3 inches) |
| MicroTroughXL | Extended (Precision Plus) trough, inner area 39,3 x 5,9 cm (15,5 x 2,3 inches) |
Standard accessories
| Layer X Deposition accessory | Dimensions: Dipper diameter 30 mm, length 100 mm. Attaches to the rail guide on the base plate Langmuir-Blodgett-deposition mechanics. Maximum substrate size is 40 x 28 mm (XS) / 40 x 50 mm (XL). |
| RT-100 Ribbon trough | Uses concentric PTFE ribbon to compress the film, making very high surface pressures accessible. Can be combined with LayerX. Allows fluorescence microscopy and spectroscopy measurements. |
| MicroSpot surface potential sensor | Resolution better than 1 mV. Attaches to the rail guide on the base plate mechanics. Simultaneous measurement of surface potential and surface pressure are possible with subphase volumes starting from 3 ml. Subphase can be magnetically stirred. Excellent signal/noise ratio. |
| TCP Temperature control plate | Connects to a circulating water bath (bath not included). |
