This Forma Scientific CryoMed 8175 CryoPlus II Cryochamber is in good condition and was removed from a working environment. This cryochamber came from a local lab that had surplus lightly used equipment and was in use prior to removal. Although we do not have the means for full testing (lack of LN2) we are offering a 30 day full money back return policy on this unit. Buyer handling return shipping. We urge customers to view all photos as they show overall condition, included accessories and functionality. We will be happy to provide additional information as well as photos so please feel free to contact us with any questions. Please Note: As seen in photo #4 The key for the keypad control lock is unfortunately broken off inside the lock. Turning the lock is still possible however. Also note the chamber lock key is included but is bent (see photo #6). Key and lock are still fully functional. These issues are reflected in the list price. Chamber dimensions: 28" depth by 20" diameter (approximate) Description The Thermo / Forma Scientific 8175 Cryomed / CryoPlus II Liquid Nitrogen Storage Vessel has a 10,000 2.0mL vial capacity and is a liquid nitrogen container with liquid level control/alarm and by-pass system. The CryoPlus series of liquid nitrogen storage system combines the well insulated storage tank with a microprocessor based controller. The exterior is constructed of fiberglass with a stainless steel interior. The unit features counterbalanced, lockable lids and heavy-duty casters. The microprocessor controller features a control/alarm system which continuously monitors the level of the liquid LN2. All system functions and components are monitored by an extensive, self-diagnostic program. The operating and alarm set points are easily programmed using the touch pad control panel. The non-volatile memory stores operational functions and alarm sequences. Once programmed, the control panel may be locked to prevent unauthorized entry or inadvertent program erasure. Double fill solenoid valves assure positive liquid nitrogen transfer. If the microcomputer detects a fill valve or liquid nitrogen supply problem, visual and audible alarms are activated and remote alarms contacts change state.
