Features
. 3H refrigerator system should be guarantee lower than 0.3K temperature range for 24hours and 0.35K for 4hours
. Wide range of experimental inserts should be compatible including basic insert, variable temperature insert
. Ultimate performance to the flexible range which uniquely separates the cooling platform from the experimental services
. With enhanced cooling capabilities through it's special design, the powerful system is fully compatible with other refrigerator systems.
