This isn’t just any old freezer. This is used to store biological and chemical materials – vital to Dr Vaja's experiments – which need to be carefully stored at temperatures as low as -25°C.

Organisation is key when Dr Vaja is running lots of different experiments in the lab. He carefully stores substances and drugs so that he can find them easily.

Regular scales just wouldn't do it in a medical research lab. Dr Vaja needs specialist scales like these, to measure the smallest amounts of substances - sometimes as little as 1000th of a gram.

Dr Vaja uses a vortex mixer just like this one, to rapidly mix samples of substances used in his experiments.

No research lab could work without well plates. Really, this is just a technical term for a float plate which contains lots of small test tubes. It's crucial for finding life saving cures and treatments.

This equipment is used to separate substances with different densities (for example, to separate cells from plasma when studying blood samples) by spinning them at high speed.

This is alcohol, but not as you know it. IMS is an extremely strong alcohol solution which Dr Vaja uses for keeping his lab and equipment clean.

You've got to be careful in the lab, especially when using glass test tubes and needles. Dr Vaja keeps one of these to hand, avoiding dangerous contamination.

Dr Vaja uses pipettes like these to measure tiny volumes of liquid (as little as 1/1000th of a millilitre), including ibuprofen. He then examines the impact the drugs have on the cells grown in his lab.

Weighing scales are used to determine the weight of mass of a sample. Dr Vaja and his team use scales like this one to determine the weight or mass of the samples used in their experiments.

Dr Vaja uses a microscope to examine and prepare tiny blood vessels (less than one millimetre in size!) for use in his experiments. He'll then look to see how these vessels react to certain drugs, and draw up his results.

The container is filled with heated water and sed to incubate samples in Dr Vaja's experiments. The bath is able to keep the samples at a constant temperature so Dr Vaja can monitor them over a long period of time.

In heart surgery, Dr Vaja would use a bypass machine like this to act as his patient's heart and lungs, helping to pump blood and oxygen around the body. When the pandemic hit, his ward had enough of these special machines to care for severe coronavirus patients.

Injecting medication is vital when caring for patients, including those with coronavirus. Dr Vaja used a little pump like this to let out a small amount at a time, making it more comfortable for his patient.

This clever machine acts as a filter. It helps to purify blood when the kidneys aren't working properly. In severe coronavirus cases, the kidneys can be badly damaged, so having one of these on the ICU was crucial for Dr Vaja.

Machines like this have helped Dr Vaja save so many lives. Ventilators help a patient to breathe normally when they can't do it alone. In severe coronavirus cases, this could be a matter of life or death.

For Dr Vaja to administer the right care to his ICU patients, he needed a monitor so he could keep an eye on their heart rate, blood pressure and blood oxygen levels.
