HNZXIB Ultra-Low Temperature Freezer 28L ULT Deep Freeze Dual Cooling

Description

Product Overview

The HNZXIB 28L Ultra‑Low Temperature Freezer is engineered to meet the rigorous demands of modern biological research facilities. With a compact footprint of 22 x 19 x 30.9 inches and a robust stainless steel door, this unit combines durability with a sleek, professional appearance. The freezer operates at a chilling capacity of -136 °F, making it suitable for long‑term preservation of cells, tissues, and other critical samples. Its dual cooling system, featuring a copper tube evaporator and condenser, ensures rapid temperature recovery and maintains a stable environment even during frequent door openings. The 28‑liter interior provides ample space for sample racks, while the single‑compressor design reduces mechanical complexity, leading to a lower failure rate and easier maintenance. Energy consumption is kept to a modest 300 watts, reflecting an efficient design that helps laboratories control operating costs.

Usage

This freezer excels in a variety of laboratory settings, including academic research labs, pharmaceutical development centers, and clinical biobanks. It is ideal for storing cell lines, primary tissues, DNA extracts, and other temperature‑sensitive materials that require ultra‑low conditions. The freestanding installation type allows it to be positioned on standard lab benches or dedicated refrigeration zones without the need for specialized mounting. Users should pre‑cool the unit to the desired set point before loading samples, and it is recommended to load items in batches to maintain optimal thermal performance. Regular cleaning of the condenser—approximately every three months—helps preserve heat dissipation efficiency and prolongs the unit’s service life.

Why Choose Us

Choosing the HNZXIB Ultra‑Low Temperature Freezer means investing in a solution that balances cutting‑edge technology with practical reliability. The full copper tube refrigeration system provides superior heat exchange, while the 304 stainless steel liner resists corrosion and contamination. The double‑door seal and 120 mm thick insulation layer work together to minimize temperature fluctuations, ensuring that samples remain at the exact temperature required for preservation. Additionally, the single‑compressor architecture reduces the number of moving parts, translating into a lower probability of mechanical failure and reduced downtime. Our commitment to quality is backed by comprehensive after‑sales support, including technical assistance, spare‑part availability, and a responsive customer service team ready to address any concerns.

FAQ

What is the recommended procedure for loading samples?

First, allow the freezer to reach the set temperature. Then load samples in batches rather than all at once to avoid sudden temperature spikes. Close the door promptly after each loading session to maintain the internal environment.

How often should the condenser be cleaned?

We recommend cleaning the condenser approximately every three months. This routine helps maintain optimal heat dissipation and ensures the unit continues to operate efficiently.

Can the unit be used for continuous operation?

Yes, the HNZXIB freezer is designed for continuous use in demanding laboratory environments. Its single‑compressor system and robust construction support long‑term operation without compromising temperature stability.

Is there a warranty or service plan available?

The freezer comes with a standard manufacturer warranty covering parts and labor. Additional service plans and extended warranties can be arranged through our sales team to provide extra peace of mind.

What power requirements does the freezer have?

The unit operates on a standard 110‑volt supply and draws approximately 300 watts, making it compatible with typical laboratory power infrastructure.
