Machines

The range of machines and associated techniques employed by our group allows us to test silk under a wide variety of conditions and environments. Combined with our unique modelling capability we aim to turn this wealth of data into information regarding the structure-function properties of silk.

The following is a list of our in-house equipment:

Dynamic Mechanical Thermal Analyser (DMTA)
TA Instruments Q800 DMTA Specifications

Description: DMTA allows the measurement of a material’s stiffness in multiple modes of deformation against a range of temperatures (-150 – 600C). This provides information regarding the modulus of the material and quantifies mechanical transitions on the basis of time (frequency and rate), temperature and humidity. More
DMTA

Accessories: Humidity accessory, Low temperature option, complete clamp set (dual cantilever, tension film fibre, shear sandwich, powder clamp, compression submersion, submersion 3-point bend, submersion 3-point bend)

 

Differential Scanning Calorimeter
TA Instruments Q2000 DSC Specifications

Description: DSC subjects a sample to a thermal gradient and measures the amount of energy required to bring the sample to a set temperature. This provides information regarding heat capacity and quantifies energetic transitions within a material (endo or exotherms). More

DSC

Accessories: 50 sample autosampler, intercooler (-90 – 600C)

 

Thermo Gravimetric Analyser
TA Instruments Q500 TGA Specifications

Description: TGA measures a samples change in weight with respect to temperature. This provides information regarding thermal degradation and water content (ambient – 1000C). More

TGA

Accessories: Range of crucibles.

 

Rheometer
Bohlin Gemini HR Nano Malvern Instruments Specifications

Description: A rheometer enables the mechanical properties (viscosity, modulus) of viscoelastic materials to be determined as a function of time and temperature. More

Bohlin Gemini HR Nano Rheometer

Accessories: Range of cone-and-plate and parallel plate geometries.

 

Tensile Tester
Zwick Zwicki-Line Z0.5 Specifications and PDF

Description: Our new tensile tester allows deformation testing of fibres, films and composites to better accuracy and with less noise than was previously possible, in a logical and efficient workflow package.  More


Metripol

Accessories: Clamps, load cells, integrated software.

 

Tensile Tester
Instron 5542 Specifications and Custom microtensile tester

Description: Samples (fibres, film, composites) are deformed  by pulling them apart, providing information regarding material properties under tension. To get the best from the raw data custom analysis software has been developed. More

Instron

Accessories: Multiple load cells and clamping options.

 

Fourier Transform Infra-Red (FTIR) Spectroscopy
Thermo Nicolet 6700 FTIR Specifications

Description: FTIR is a measurement technique for collecting infrared spectra, this provides a chemical fingerprint of a material, this is extended through incorporation with a microscope and microscope stage to allow chemical mapping of a sample down to micron resolution. In conjunction with the cryostat it is possible to analyse how the molecular structure/organisation of a material changes in response to temperature (-50 – 600C) More

FTIR

Accessories: Two detectors (MCTA and TEC InGaAs), Transmission mode, Diamond ATR, Diffuse reflectance, FTIR Microscope, motorised stage with >10µm resolution, Oxford Instruments Cryostat, Heated "Golden Gate" Single reflection diamond ATR accessory

 

Quantitative Polarisation Microscope
Metripol System Oxford Cryosystems

Description: The Metripol system permits quantitative measurement of the orientation and amount of birefringence in a sample which provides information regarding its molecular structure and organisation.  More


Metripol

Accessories: 6 filters, narrow and broad spectrum, range of air, dipping and oil objectives.

 

Scanning Electron Microscope
Jeol Neoscope JCM-5000 Specifications

Description: This is a benchtop solution for scanning electron microscopy. By using a beam of electrons instead of light it is possible to visulaise objects that are smaller then the size limits of conventional light microscopy.The increased depth of field and resolution allows for finer details to be resolved and sub-micron strucutres to be characterised.  More


SEM

Accessories: Holders and mounts for practically all SEM stubs

 

Laser Vibrometer
Polytec PDV-100 Portable Digital Vibrometer Specifications

Description: A laser is used to measure vibrations on solid surfaces (e.g. spider web). Being a non-contact method, the vibrometer is very useful at picking up a range of cryptic or small amplitude vibrations 0-22 kHz. Raw time-velocity data can be transformed through accompanying software into frequency-magnitude plots, providing data on vibration propagation, resonance and damping.  More


Vibrometer

Accessories: battery or mains powered, portable for the field up to 30 m working distance

 

Automatic Expresso Machine
Gaggia Titanium 90500 Specifications

Description: This is a benchtop solution for research stimulation. By using two boilers it is possible to eliminate wait time between brewing and steaming. With features like the automatic frothing attachment, stainless steel turbo frother, bypass doser, adjustable coffee strength and grind settings, new ideas are brewed up in no time.  More


Titanium Gaggie

Accessories: Automatic frothing attachment, bean hopper bypass doser
