Unless is mandated by the state, or the price is heavily discounted, nobody in their right mind will choose to buy anything outside of the well-known foreign manufacturers of scientific instruments.
I ask you, if you have assembled a team and you are ready to start making experiments on a specific field (physics, material science, biotech etc) which could last for up to 3 years, would you gamble you entire research being invalidate due to using an unknown supplier for scientific instruments?
And if that unknown supplier's scientific instruments have "only" 99.5% accuracy while the foreign suppliers have 99.99%, would you use the domestic or the foreign supplier?
Impossible. Either mandated by the state, or heavily discounted, or total export ban from Western countries
