The unique sensitivity and
small subphase volumes
allow for accuracy and
sample cost savings.

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

• Measurement 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).
