The Pol-Eko ZLN 85 Laboratory Freezer can freeze and store samples and biological materials for research, offering an effective storage solution for short-life materials. The ZLN 85 freezer is at the smaller end of the Pol-Eko freezers range, with an 85L capacity. It comes with two stainless steel shelves as standard, with the option to add an additional two, if required. The freezer offers complete control, allowing you to set customisable temperature programs, including ramp times; all of which are completely recorded for you at the touch of a button.

Pol-Eko freezers can be customised to meet the requirements of your application, making them an ideal investment for your laboratory. The ZLN 85 freezer can be fitted with wheels, table, or castors, if required, giving you full control over your lab layout. Choose to have a chamber monitoring camera fitted, so that you can see what is happening inside without opening the door. The 85 in the name refers to the capacity of the freezer. You can find freezers with a bigger capacity here.

As with most Pol-Eko laboratory equipment, the ZLN 85 Freezer can be customised to meet the requirements of your lab. Choose a Smart or Smart PRO controller (See full details below). To discuss further options available, talk to our team on 01257 270433.
