Atomic Force Microscope ( SPM complete system)

Scanning Probe Microscope, (AFM-SFM)

0ptical Microscopes inability to image sizes smaller than wave length of visible light resulted invention of nano-scopes in the last decade.

AFM is the top of the list ,due to its low price and multi-applications.

The basic principle of AFM

A spring micron size cantilever has a conical tip at its free end. The conical tip with a very sharp end, usually less than 10 nanometres, scans the sample surface from a very close nanometric distance.

As the tip moves over the surface the Van Der Waals forces between atoms on the sharp end of the tip, as a side note the tip is one atom in diameter, and the atoms on the surface of the sample varies, resulting vertical displacements of the cantilever.

Vertical movements of the cantilever are reflected using a laser to magnify the movement of the cantilever.

The reflected laser beam from the cantilever’s highly polished upper surface hits a quadruple photodiode.

The output signals of the photodiodes are related to the vertical movements of the cantilever which in turn represents the surface topography of the sample.

The whole system is light weight, portable and accurate.

Easy to use.

Atomic Force Microscopy ( AFM) also known as Scanning Force Microscopy (SFM) is very high resolution type of Scanning Probe Microscopy (SPM) with a benefit of 1000 times better than Optical Diffraction limit. Resolution in the order of a nanometer

Compact Desktop SEM Sputter Coater DSR1 - Vactechniche

DCT Turbo Desktop Carbon Coater for SEM/TEM Sample Prep

DESKTOP CARBON COATERS

SEM/TEM Preparation Carbon Coater, Low and high vacuum systems

Sample preparation using Carbon coating is the recognised method for non-conductive and low conductive specimens or samples.
The DCT system is a versatile carbon evaporator for preparing specimens for electron microscopy or EDXA analysis. It has been designed as a high-current power supply capable of evaporating both carbon rod and carbon fibre. In other words, it can coat carbon on different types of substrates for X-Ray analysis and coating conducting carbon fibre & rod for SEM analysis.
The excellent design of the system enables the user to easily load and unload samples, and quickly replace the carbon fibre/rod. The system is equipped with a film thickness monitor (FTM), which measures the coating thickness on a quartz crystal mounted in the vacuum chamber with an accuracy of 1 nm. The system can automatically terminate a coating cycle when the required thickness or time has been achieved..
The compact and easy to use carbon coater, has the option of using existing pumps or supplied with a pump.
For external pumping the on board computer controls the pump or pumping rig.
Larger samples can be accommodated with our increased vacuum chamber DCR-L and DCT-L system
Carbon Coating
Due to its excellent transparency and good electrical conductivity, deposited carbon thin films are widely used for either electron microscopy (EM) or X-ray microanalysis applications such as:
• support films for TEM (high vacuum (HV) evaporation)
• conductive films for SEM/EDS samples (low vacuum evaporation)
• conductive surface films for non-conductive microprobe samples (HV evaporation)
• conductive surface films for non-conductive EBSD samples (HV evaporation)
• conductive surface films for non-conductive FESEM samples (HV evaporation)
• conductive surface films for non-conductive FIB samples (HV evaporation)
Our board computer integration makes the Desktop Sputter coater an ideal laboratory and research tool for scanning electron microscopy (SEM) and Tunnelling electron microscopy analysis(TEM).
Thin films of about 5 nm (50Å) are used for particle support and as an isolating layer in autoradiography. Thicker films are also used in SEM and X-Ray Microanalysis. In general, deposited thin films should be uniformed with fine grain sizes and reproducible film thickness.
Carbon rod and carbon fibre are the two widely used sources for carbon evaporation in laboratories around the word. They each have their own features that make them of specific interests to the users. For a better understanding, further details of these features are presented in the following sections.

Carbon Rod versus Carbon Fibre Evaporation

Evaporating carbon thread or a pre-shaped carbon rod are both common methods to evaporate carbon. Using pre-shaped rods with the correct control system (pulse, continuous and auto) delivers a high quality carbon layer and also gives good control over the thickness of the carbon layer. However, some users prefer to use carbon fibre because it has a faster and simpler process comparing with carbon rod.

ELECTROSPINNING UNITS

Laboratory Electrospinning Unit (Electroris)

Electrospinning is an established method of producing nano- and micro-fibres from a wide variety of natural and synthetic polymers is knows as  Electrospinning

The method used to produce these fibres is as follows:

By introducing a  polymer solution at a constant flow rate though a small restriction such as a syringe needle.

A high voltage, typically 10 to 30 kV is connected to the needle; it is the applied voltage that induces a charge on the surface of the liquid droplet, when a critical charge is reached, the physical shape of the droplet surface changes, the hemispherical surface of the fluid elongates and a Taylor cone forms.

By applying a greater voltage the now charged droplet , the charged liquid jet is ejected from the Taylor cone and attracted to the earthed collector, which is positioned at a fixed distance from the needle. During this process the solvent evaporates from the polymer solution, leaving dry polymer fibres on the collector.

Our lab scale electrospinning machine has the ability to prepare polymeric/ceramic nanofibers with diameter range of 50 nm to a few microns. Electroris® electrospinning setup mainly consists of main body including syringe pump, spinneret, collector system and high voltage power supply. Two different types of Electroris are available:

  • Standard model
  • Dual pump Electrospinning system (Side by Side Electroris).

In side by side Dual pump Electrospinning system, there are two syringe pumps on both sides of the rotating collector drum;

  • 2 syringe pumps,
  • 2 scan systems,
  • 2 distance adjuster and
  • 2 High-Voltage Power Supply.

Production rates will be twice that of the standard model,

Main advantage of this model.

  •  two different materials can be electrospun simultaneously.
  •  Electro spin polymeric material in one side with additive materials such as medications can electrospray from opposite side.

 

With this flexibility in design, our equipment is especially suitable in:

  • Pharmaceutical,
  • Medicine,
  • Biology, bone and Epidermis porosity replication
  • Material Science research. Also, it is useful in the manufacture of
  • Composite nanofibers.
  • Ceramic nanofibers.

Our device controls the electrospinning parameters including injection rate of polymeric solution, electrospinning distance, rotating speed of collector drum, working temperature (room temperature to 45°C) and working time. Electroris® supplies sufficient safety scheme for users with respect to the handling of a high voltage power supply and chemical solvents.
