ABS Auto Jr, 6000 Vials

Product Number: AJ-IV

The unique fiberglass restricted-opening neck design of the ABS Auto Jr. reduces LN₂ consumption rates far below other auto-filling units. Under laboratory testing providing one opening per day, the ABS Auto Jr. operated and maintained “cryogenic temperatures” for over a month on one 180-liter LN₂ supply tank. Competitive units can consume three or four supply tanks per month. 

The Auto Jr is the economical auto-fill for every lab. Every Auto Jr comes standard with: 6ft. stainless-steel armor-plated transfer hose, 1/3 year parts and labor warranty, roller base, stainless steel inventory racks, and the Sentry LN2 Controller.

ABS Auto Jr. package systems are also available, including: ABS Auto Jr. Tank, Sentry LN2 Controller, stainless steel rack inventory system, transfer hose, CryoGloves, LN₂ measuring rod, and either fiberboard boxes (25 cell, 81 cell, 100 cell, or custom) or polycarbonate boxes (25 cell, 81 cell, or 100 cell).
