Measuring the glass syringes temperature

As part of a validation, I would like to measure the temperature of glass syringes, just after the autoclave outlet. Are there any instruments for measuring the glass temperature knowing that syringes are very small?
The product has to be put in is heat sensitive!

How about infrared thermometers ?

Second that suggestion. They are optical devices which read and measure the temperature using waveleangth analysis. The only limitation is the the accuracy is typically around 1 C (maybe down to 0.5 C).
