E-Z Freezin®-"MFR5"  extender is recommended for equine frozen semen breeding programs.The original "MFR5" version is a Modified French formula that contains the cryoprotectant glycerol and Ticarcillin as a preservative. E-Z Freezin®-"MFR5" can be processed at room temperature or cooled to 5? C prior to freezing. Recent studies have shown that both methods can be used with these extenders. In general, pre-cooling to 5? C prior to freezing is beneficial for most...

E-Z Freezin®-"LE"  extender is recommended for equine frozen semen breeding programs.The original "LE" version is a Lactose EDTA formula that contains the cryoprotectant glycerol and Ticarcillin as a preservative. E-Z Freezin®-"LE" can be processed at room temperature or cooled to 5° C prior to freezing. Recent studies have shown that both methods can be used with these extenders. In general, pre-cooling to 5° C prior to freezing is beneficial for most stallions but is not...

Custom Cryomax™ LE CF1 Freezing extender Custom E-Z Freezin® Cryomax™ LE CF1 Equine Semen Freezing Extender is designed for stallions that are "poor freezers" in other commercial freezing extenders.  Cryomax™ LE CF1 is similar in composition to the standard Cryomax™ LE without the large molecule cryoprotectant glycerol.   Recent research has shown that most stallions semen freezes best in extenders that combine both large and small molecule...

Custom Cryomax™ LE CF2 Freezing extender Custom E-Z Freezin® Cryomax™ LE CF2 Equine Semen Freezing Extender is designed for stallions that are "poor freezers" in other commercial freezing extenders.  Cryomax™ LE CF2 uses a completely different small molecule cryoprotectant than is found in the standard Cryomax™ LE and it is also glycerol free. Recent research has shown that most stallions semen freezes best in extenders that combine both large and small...
