Chemistry Lab
Our wet chemistry lab is for the production of graphene inks and development of new methods of producing graphene and other 2D materials.
For lab inductions, please contact processtech@graphene.cam.ac.uk (Giuseppe Russo). For any tool enquiries, please contact the lab leader Dr Boyang Mao, or deputy Dr Vaishakh Kedambaimoole. For training on any of the equipment, please make a request through PPMS.
While there is a range of devices in the wet chemistry laboratory, several of them require booking before use. The booking system can be found here.
Thermo Scientific Sorvall Centrifuge
Thermo Scientific™ Sorvall™ WX+ ultracentrifuge series. Spinning up to 100,000 rpm, these Sorvall WX+ ultracentrifuges deliver the speed and performance required for your high performance processing applications. Plus they feature lightweight and fatigue-resistant Thermo Scientific™ Fiberlite™ carbon fiber rotors that do not need to be derated over time, and an intuitive, easily accessible touch screen interface and imbalance tolerance to accelerate run set-up. The full specification can be found here. |  |
Beckman Centrifuges: Avanti and Proteome
The Avanti® J-26S centrifuge series combines high performance, complete BioSafety systems, and long-term durability, making it an incredibly capable choice for any lab environment. Experience simplified high-throughput sample processing and more control with powerful features including an automatic rotor identification, low heat output, imbalance tolerance, quiet performance and ergonomic design features. The full specification can be found here 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. The full specification can be found here. |  |
Beckman Ultracentrifuge
The Beckman Optima MAX Ultracentrifuge Series is a microprocessor-controlled tabletop systems that generates high centrifugal forces for a variety of high-speed applications. The Beckman ultracentrifuge design features a variable-frequency induction drive and rotor overspeed identification 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, aluminium, 4 x 2.2 mL, 55,000 rpm. |  |

Large Sonication Bath
The new Elmasonic S Cleaning Units provide state-of-the-art microprocessor-controlled ultrasonic cleaning and sweeping technology with a user-friendly LED display to ensure excellent operation. |  |
Speed Mixer
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
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. |  |
Homogenizer x2Principal User: Dr Boyang Mao PSI-40, Adaptive Instruments This pharmaceutical grade homogenizer is the ultimate in high pressure product processing, with less than 70 dBA noise output. It has a fixed geometry processing chamber and is capable of more than 2000 bar pressure with a throughput of 60 litres per hour. This delivers an extremely fine and uniform particle size distribution. The PSI-40 can be operated in both closed and open loop configuration in a continuous range of 60 ml to 60 litres per hour. There are a range of various processing chambers available for use in emulsification, de-agglomeration and particle size reduction. The PSI-40 is offered with this wide range of functionality and is also the most compact and quietest system in this product category. |  |
