Product Description
Protect cell viability and sensitive samples without ice buckets, alcohol baths or consumables. The 12-tube freezing boxes give a steady cooling rate of about 1°C per minute in a -80°C freezer, while the 30-tube cool box system keeps samples between -18°C and 4°C on the bench or during a power outage.
This listing is for NEST catalog number 200103: Ice-Free Cool Box System for 30 x 2 mL Tubes, with Aluminum Tube Block and Freezing Block. The 12-tube boxes are made of solid polyurethane foam with no moving parts, and they can be handled straight from the freezer without gloves. The 30-tube system pairs an insulated cool box with a machined aluminum tube block and a freezing block for even temperature distribution, holding samples below freezing for about 4 hours with the lid on. Both designs are reusable thousands of times. LIGHT LABS carries the full NEST Scientific catalog with knowledgeable support when you need it.
