VTC-200 is CE certified compact spin coater with vacuum chucksdesigned for easy and quick coating via sol-gel for wafers up to 8" diameter or 5" x 5" square. The spinning speed is variable from 500-6000 rpm with two programmable segments. The heatable cover is optional, which allow drying sample after coating. SPECIFICATIONS: Structure Aluminum casting case to keep spinning stably Drainage outlet and vacuum pump connector are on the back panel One filter is included in the standard package. It is used to connect the pump and coater for preventing wastewater from flowing into the pump One oilless pump is included in the standard package. Chamber & Vacuum Chuck The chamber diameter is 250 mm and can accept wafer 8" Dia max. or 5"x5" square The spinning chamber is made of PP which is corrosive resistant One 6" vacuum chuck and chuck o-ring are included for holding 6" and 8" wafers 1 piece of Adhesive tape (6'' W x 24'' L) is included for coating irregularly shaped substrates or wafer with size < 6" Place the irregularly shaped substrate on the adhesive tape, then the vacuum chuck will hold the tape by suction Spin Speed Digital control panel with two programmable segments of different spin times and speeds 500 - 6000 RPM adjustable spinning speed for each segment Liquid Injecting 20mL syringe is used to contain the coating material The syringe holder height can be adjusted and rotated freely along the support rod - Pic. 1 - Pic. 2 Optional You may choose Precision Electronic Single Channel Pipette: 20 - 200uL for more accurate coating (Click Pic 1) Using plasma cleaner to treat substrate surface before the coating can improve film quality You may consider our new product: Heatable syringe (Click Pic 4) Vacuum Flash Assembly for DIY Vacuum Flash-Assisted Solution Process (VASP), Up to 5 mTorr is available (Click Pic 5) Pic.1 Pic.2 Pic 3 Pic 4 Pic 5 Heating cover with digital temperature controller up to 100°C (max. duration < 1 minute) is available at extra cost ($2495) , which allows sample drying in-situ during and after coating. Click demo video below for detail Pic 6 Pic 7 Input Power AC 110V/220V selectable There is a built-in power socket on the right side of the VTC-200 spin coater. It is used to supply power for the vacuum pump. The output voltage of this power supply depends on the input voltage of the spin coater's main circuit. (e.g. if the spin coater is plugged into the AC 110V power socket, then the built-in power socket will supply AC 110V) Motor Power 90VDC, 150W Product Dimensions 500mm(L) x 400mm(D) x 400mm(H) Net Weight 20 kg (44 lbs) Compliance CE Certified NRTL certification is NOT available. Warranty One year limited with lifetime support Rusting and damage due to improper storage condition or maintenance are not covered by warranty Application Notes Please clicks here to review an article on "Spin Coater Theory and Processing" Do NOT use two-stage, molecular vacuum pumps due to low vacuum design and oil evaporation In order to achieve optimal coating quality, please consider cleaning substrates by a plasma cleaner (click the picture below for more details) prior to coating. This will significantly reduce the surface tension on the substrates Cleaning instruction for the spin coaters. You may consider our new product: Heatable syringe 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 fabric cloth to wipe out the residues remain in the bow/base. If necessary, turn on the water outlet when flushing the water bowl/base to avoid liquid overflowing during the operation. For more details about the cleaning procedure, please review the cleaning instruction for the spin coaters.
