Thank you for your question. I am sorry about your carpal tunnel syndrome as this condition is really painful and affects your daily functioning in a lab. To answer your question, there are several ergonomic features incorporated within the cell culture flask, dish or plate to enable better handling and easier access to cells during culture.
TPP flasks are shorter in length to only provide you a fully treated cell growth area with zero dead space but also a better grip on the flask during handling. In the mapping out and designing TPP cultureware, the scientists made sure that hard to handle products like well plates had grip edges on the sides for better handling. Also, each plate, dish and flask, when placed in a stack, interlocks with each other to prevent toppling over during transport from the incubator to the hood and vice versa. The TPP dish has the most pronounced grip edge ring to a) prevent accidental dropping of the dish bottom from not grabbing the dish as a whole and just lifting off the top and b) to prevent contamination of the inside of the dish with the accidental exposure to the gloved hand during lid lift off. Another key product that is ergonomic is the TPP serological pipettes that are shorter in length and hence prevent the back and neck strain that results from hours of constant pipetting in the hood.
All in all, a lot of thought, design and ingenuity laid the foundation for the production the Premium TPP cultureware and I hope I was able to provide you with some examples to demonstrate that.
