FEATURES

Spotting Uniformity
STS pins achieve 10% spot diameter consistency for each particular pin and 15% diameter consistency across multiple pin ( when printing with the same buffer, using surfactants in the buffer composition ) Printing with plain water or salt based buffers with high surface tension may increase spot size variation
Deposition Repeatability
15% for the same pin and 22% across multiple pins ( for the same buffer ). Deposition volume repeatability is proportional to the power 3 to the spotting uniformity. 10% spot diameter variation results in 15% volume variation.
Zero Cross-sample contamination
Simple cylindrical shape of pin tips allow quick and effective cleaning in water reservoir and vacuum dryer.
Corrosion Resistance
STS pins tips are made of corrosion resistant stainless steel. They inert to most organic solvents, but corrode in higher concentration acid and alkaline solutions.
Wear Resistance
STS pins withstand hundreds of thousand hits against glass without notably changing shape of the tip.
Easy Handling
STS pins due to solid tip and overall simple construction are the easiest option in terms of handling and cleaning during print runs and between operations.
