Laboratory warming plates are mainly used for maintaining the temperature of sperm samples during analysis and for keeping follicular fluid and oocytes at 37^°C during oocyte pickup. They are frequently combined with warming blocks (Link zu Warming blocks) for perfect adjustment to dishes or tubes. Heat is passively transmitted to any type of warming blocks without any loss. Warming plates can also be used to pre-heat instruments or disposables or for seamless integration into table plates The anode treated aluminium surface is extremely resistant. The temperature range is between ambient and 55°C with an accuracy of ± 0.2^°C. Warming plates require HT control units. Large sizes have to be connected to controllers with high heating
