Ultra Low Deep Freezer Manufacturer,Supplier and Exporter in India

Product Code : EL-RE-2300
Jlab Export is a leading Ultra Low Deep Freezer Manufacturer,and suppliers in India

This ultra-low deep freezer holds samples as cold as −80 °C and is built in horizontal (chest) or vertical designs. Its stainless steel interior sits inside a powder-coated, cold-rolled steel cabinet with 127 mm of foamed-in-place polyurethane insulation. A triple-point door gasket and inner polystyrene sub-lids keep cold air in when the door is opened, and a microprocessor controls and monitors the temperature.

How the Cabinet Holds Its Cold

Door openings are the main source of warm air in an ultra-low freezer. The inner sub-lids divide the opening, so only the section in use is exposed and the cabinet recovers faster once the door shuts. The thick foam walls cut power use and hold the set point, and a washable filter keeps dust off the condenser. Locking castors of 2 in let the cabinet be rolled into place and fixed there.

Sample Banking Practicals for Biotechnology Students

Biotechnology and biochemistry students learn to bank material for later experiments. Plasmid preparations, enzyme aliquots and bacterial cultures mixed with glycerol go into Storage Vial With O Ring tubes, whose O-ring cap keeps them leakproof in the cold. The vials are filed in an alpha-numerically marked Cryo Box (PP), and each position goes into a freezer map.

A second exercise tests storage itself. Students divide one enzyme into small portions, thaw a fresh portion each week and compare it with a portion that has been thawed and refrozen every week. Groups that keep cryo vials can mark theirs with colour-coded Cryo Coders in the caps.

Frequently Asked Questions

Why does the door have inner sub-lids?
The polystyrene sub-lids sit under the main door and divide the storage space. You lift only the one over the rack you need, so the rest of the cabinet stays covered. Less cold air escapes, and the temperature recovers sooner after the door is closed.

What are the 25 mm access ports for?
They let a separate temperature probe, recorder lead or instrument cable pass into the chamber without holding the door open. Many labs run an independent probe through a port as a second check on the freezer reading.

How often should the condenser filter be cleaned?
Check it regularly, and more often in a dusty room. The filter lifts out easily and can be washed, dried and refitted. A clogged filter lets dust reach the condenser, which cuts refrigeration performance and puts the samples at risk.

Which temperature version should I choose?
Match it to the coldest material you will store. Bacterial glycerol stocks, RNA and purified proteins are commonly kept at −70 or −80 °C, while many reagents and kits need only −20 °C. Check each product label before you decide.

How should a new freezer be loaded?
Let it reach its set temperature empty, then add warm material in small batches so the cabinet can recover between them. Store samples in boxes on racks rather than loose, and keep a map of positions so the door is open for less time.
