Upper cooling system<br />

28 Version 1.02 04/24/2013<br />

Fig. 10: Upper cooling system<br />

1 Initiation needle<br />

2 Cooling nipple<br />

The initiation needle (fig. 10/1) of the upper cooling system "inoculates"<br />

the sample with ice crystals ("crystallization"). This causes the<br />

sample to freeze and heat up to its freezing point.<br />

WARNING!<br />

Risk of infection from sample residue!<br />

The initiation needle is immersed into the sample during<br />

measurements. Contact with the initiation needle increases<br />

the risk of infection.<br />

- Wear lab gloves during any kind of work.
