description: Ultracold mixture experiments provide a great platform to study fundamental physics  as well as to develop quantum technologies. Improving the reliability and stability of  these platforms still remains as a significant challenge to be solved. In this thesis,  work is carried out to improve a sodium-lithium ultracold mixture platform. Stability  of Bose-Einstein condensate production is improved, as well as the ability to  exercise more precise control over the internal states of both species.  To improve the stability, the vacuum and optical setups are simplified and each  experimental stage is optimised. Better control of internal states via long Rabi cycles  is managed by improving the magnetic field stability. Local confinement is  achieved using an 1D optical lattice at 610 nm. The imaging and the microwave  system are characterised using the optical lattice. Additionally, progress has been  made towards observing single atom dynamics in a sodium MOT with fluorescence  imaging.
