Manual Ultra Trace Liquid Nitrogen Pump-405
Are you still poring LN2 into small vessels by hand?Safe filling of small vessels;Hand controlled administration of smaller amounts of LN2, for fillin
Product details
405 series applications:
- hand-controlled filling of small dewars;
- hand-controlled cooling of small objects;
- hand-controlled freezing of small samples;
- hand-controlled filling of Dry Shippers;
- hand-controlled cooling of small chemical reactions.
405 series advantages:
- the system can deliver LN2 liquid just with a press on the pump head： this means that the system is ready for use 24 hours a day
- the system delivers LN2 without any pressure：this means without noise, vibration, excessive waste, etc.
- there is no external LN2 valve required：that implies no unnecessary heat input which spoils a lot of LN2
- there is no internal LN2 valve in the pump：LN2 comes out of insulated tubing without making contact to warm metallic parts, so very fast
- there is a very low thermal mass to cool down the pump：LN2 comes out within 10 to 40 seconds, depending on the level in the Dewar.
- Filling efficiency is better than 90%, due to very less loss for cooling down pump parts：there is a very low thermal connection to the ambient temperature;
- This means that the system is extremely economic in stand-by：Typical usage less than 0,5 Liter / day
- P.E.D. 99/36/EC (Pressure European Directive) for pressurized vessels does not apply for this system; The maximum possible pressure is lower than 300mBar. Therefore this system is allowed to be used inside the lab, near your working place, without danger.
