I am a PhD student who requires lots of coverslips (!!) for setting up hanging drop crystallization. The company sells it for a huge amount. Also there is a wide monetary difference between a normal siliconized coverslip and a 22mm siliconized circle coverslips. We tried to search for an alternative companies but couldn't get any one who sells coverslips with the same dimensions (0.19-0.22mm glass thickness and 22 mm glass diameter). Is there any alternative company (distribution in India) from where we can buy them for a reasonable price?

Thanks in advance for sparing your valuable time and efforts.
