Wet Chemistry

Our Wet Chemistry lab is for the production of Graphene inks, and development of new methods of producing graphene and other 2D materials.

 

For access to the lab, or for any general training, please contact the lab leader Dr Yarjan Samad, or their deputy Dr Zan Bian. For training on any of the equipment, please contact the Principal User or their deputy for the listed equipment.

While there is a range of devices in the Wet Chemestry Laboratory, several of them require booking before use. The booking system can be found here.

 

Thermo Scientific Sorvall Centrifuge


Principal User: Dr Yarjan Samad
Deputy: Dr Zan Bian

The ProteomeLab™ XL-A provides thermodynamic and hydrodynamic information about macromolecules in solution. The computer-controlled system collects absorbance data from sedimentation equilibrium and sedimentation velocity experiments. The XL-A Windows User Interface and Data Analysis Software, included with each ProteomeLab™ XL-I and XL-A, interprets the data to provide information about association states of interacting molecules, association constants, weight average molecular weight, sedimentation and diffusion coefficients and conformation changes.

Beckman Ultracentrifuge


Principal UserDr Yarjan Samad
DeputyDr George Kakavelakis

The Beckman Optima MAX Ultracentrifuge Series is microprocessor-controlled tabletop systems that generate high centrifugal forces for a variety of high-speed applications. The Beckman ultracentrifuge design features a variable-frequency induction drive and rotor overspeed identifcation system. The Optima Max centrifuge also has a program memory that can contain up to ten programs, and offers a choice of acceleration and deceleration rates. The Beckman Optima MAX-E ultracentrifuge operates at 5,000 to 100,000 rpm in 1,000-rpm increments. Rotors Available:- TLA110 - Fixed Angle, Titanium, 8 x 5.1 mL, 110,000 rpm TLA55 - Fixed Angle, Titanium, 12 x 1.5 mL, 55,000 rpm TLS55 - Swinging Bucket, Aluminum, 4 x 2.2 mL, 55,000 rpm

M110-P Microfluidizer


Principal UserDr Yarjan Samad
Deputy: Jeremiah Marcellino


M110P-30K high shear bench-top fluid processor without compressed air or hydraulic cooling water, running on a standard 120-volt, 20-amp, single-phase power outlet. The MIcrofluidizer produces stable nanodispersions and nanoemulsions, cell disruption (e. coli, yeast), and micro/nanoencapsulation in polymers, liposomes and oils.

Speed Mixer


Principal UserDr Yarjan Samad
DeputyDr Zan Bian

 

The SpeedMixer™ DAC 150.1 FVZ-K is an economical laboratory-sized Instrument for the rapid mixing and grinding of materials that would otherwise require large amounts of time and/or effort to mix and/or grind with the added advantage of a cartridge lid, enabling the user to mix directly into syringes or cartridges.

Glove Box


Principal User: Shahab Akhavan
Deputy: Dr George Kakavelakis

The glovebox contains a balance for weighing nano/micro powder materials. Loading of containers is done via a loadlock. The glovebox has a nanoparticle filter and an extractor for the safety of the operator. Any containers transferred via the load-lock must be sealed if they contain materials.

When in the Wet Chemistry laboratory, please follow the local rules, downloadable here.
