Cryogenic Vial Auto Sealer Model 516 is an automatic cryogenic vial sealing device. In these days, people still use flame gun to apply the heat direct on heat-shrink plastic to seal the vial manually; however, the quality of preserved samples is not guaranteed. It also can be one of the unstable factors cause for failure cryogenic storage outcome. The newest creative design from Hotech Instruments Corp, Cryogenic Vial Auto Sealer, Model 516 minimizes the most failure factors which may be caused by manual operation, provides standardize sealing process to assure the most efficient, safe and stable sealing quality on cryogenic vials in the world.

【FEATURES】

• Simple operation：Whole system is microprocessor controlled. Simply encircling the heat-shrink plastic over the cryogenic vial, place the vial in holder adapter, all the sealing procedures are done automatically by one-touch only. 

• Flexible adjustments：Default sealing temperature and time are preset; however, both settings are adjustable according to actual needs.

• Safe for live cells：Heats only apply on the narrow height of the upper vial; therefore, live cell will not being affected during the sealing process. The safety of the sealed sample is absolutely guaranteed.

• Seamless sealing：360° rotation plus smooth tremble-free movement makes the cryogenic vial being sealed efficiently and securely.

• Dual operations：In case for the needs of multiple vial sealing, multiple buttons are available for the repeated operations. The multiple button runs the trip 30 rounds repeatedly.

•  Emergency key：Press Reset key under any circumstance when the trip is asked to be stop. The holder adapter returns to origin position and sealing time return to default value.

• Stable performance：Microprocessor PID controlled operations, including the temperature, sealing time and movements, which assures the best sealing quality for the sealed samples.

• Secure protections：Multiple secure protections are embedded in the system. The power will be enforcedly shut off when process value temperature (PV) over the limit; on the other hand, internal ventilation takes the job to cool down the system as well. Be careful, the zone painted in red is extremely hot area, please stay away from it. 

• Fuzzy control: When the power switch is switched off, the internal ventilation will not stop until the internal temperature drops close to ambient temperature.

• Two options for the holder adapter: Common sizes adaptor for the cryogenic vials.  Easy to replace from each other, no tool is necessary.
