The Nima Range

LB Product Range

Nima Technology make a comprehensive range of Langmuir troughs and film balances. By following the trough nomenclature below, you can specify almost any combination of size, function and option.

Model No = A D B F / O1 / O2 ...

where

A = area (x 100cm²)

D = dipper type

B = number of barriers

F = primary function of trough

O1 = option 1

O2 = option 2

Nima LB Product Range Table

Area, x100cm² Dipper type No of barriers Function Option
1 = 100 0 = no dipper 1 =
1 barrier		 A = Analytical CAB = Cabinet
3 = 300 1 = conventional LB/LS dipper* 2 =
2 barriers		 BAM = Brewster angle microscopy IB = Independent barriers
6 = 600 2 = alternate layer dipper - - D or D1 = Dipping
D2 = alternate layer dipping		 IJP = Injection port
7 = 700 3 = both types of dipper - - LL = Liquid/liquid trough MST = Magnetic stirrer
12 = 1,200 --- --- M = Microscopy SP = Surface potential sensor
--- --- --- MC = Multiple compartments ---

* LB dipper = vertical Langmuir-Blodgett method
LS dipper = horizontal Langmuir-Schaefer method

Example 1: Model 712BAM:

7: 7 x 100 = 700cm²
1: Dipper mechanism
2: 2 barriers for symmetrical compression of monolayer about centre of trough
BAM: Function is Brewster Angle Microscopy

Example 2: Model 612D:

6: 6 x 100 = 600cm²
1: Conventional dipper mechanism
2: 2 barriers for symmetrical compression of monolayer about centre of trough
D: Function is conventional LB or LS dipping

Our most popular models

Langmuir film balances

LB troughs

The term 'Langmuir film balance' is used for instruments without a dipper as pioneered by Langmuir in 1917.

 'Langmuir-Blodgett trough' is used for instruments with a dipping well and dipper mechanism, as developed by Blodgett in 1930's.
[102M] 102M Microscope Film Balance

Miniature trough (100cm², 40ml) for microscope applications. With 2 mechanically coupled barriers and a sapphire window. Flat design means that it fits any upright microscope. Inverting microscope option available. Can be upgraded easily into our dipping trough, Model 112D.

[112D] 112D Micro LB trough

Micro 100cm², 45ml Langmuir trough for deposition of conventional LB layers onto substrates up to 20mm wide to a depth of 25mm. Can be converted easily into Model 102M microscopy film balance.
