VTC-50A is an economic desktop Spin Coater with a vacuumless chunk that is designed for the quality coating of sol-gel at the lowest cost. By using grooved spinning templates to hold samples on the rotating plate, the instrument provides the advantages of cost-effectiveness and ease of maintenance. Complete accessories are included for immediate use.(Upgraded to Vacuum-free sample holder since 5/22/20). Upgraded to 24VDC power input since 09/10/2020) SPECIFICATIONS: Working Voltage 24 VDC A 110 - 240 VAC to 24 VDC(50/60Hz) NRTL Certified power adapter for worldwide use is included. Structure Heavy-duty Aluminum casting case to keep spinning stably 24VDC motor Ar gas compatible for use in a glovebox Spin Plates The Chamber size is 134mm diameter, can accept wafer sample 4" diameter at Max. A 4" PTFE spin plate with the groove of 50x50mm is included, which can hold 50 sq mm, 0.3 mm thin sample plate in place during fast-spinning, so-called vacuumless holder 7 pcs of 0.3 mm thickness nylon plate is included for holding irregular samples with double-sided tape or carving, please watch the video for more details. One roll of 3M removable double-sided tape (3/4' W x 400" L) is included for immediate use Please click here to learn how to mount samples on the plate by using removable double-sided tape. It is easy and more economical than vacuum chuck. You may use a 50x50mm blank (included) plate to make different groove via a knife to fit your sample, or make an order space grooved plate from us.

This will significantly reduce the surface tension on the substrates. You may place the compact spin coater into a glove box to operate in inert gas Cleaning instruction for the spin coaters. Warnings Do not overflush the water bowl/base with any kind of liquid. Excess liquid will leak into the motor shaft and cause damage. Please use a fabric cloth to wipe out the residues that remain in the bow/base. For more details about the cleaning procedure, please review the cleaning instruction for the spin coaters.
