Taylor-Wharton K Series 3K Cryobiological Storage System

For laboratories with smaller cryogenic sample collections, simplicity, reliability, and low liquid nitrogen consumption are often more important than maximum storage capacity. The Taylor-Wharton K Series 3K Cryobiological Storage System was designed for exactly these applications, providing dependable liquid nitrogen storage in a compact, portable platform that is ideal for research laboratories, IVF clinics, veterinary facilities, and biotechnology companies.

With a 48-liter liquid nitrogen capacity, the 3K provides organized cryogenic storage for thousands of biological specimens while maintaining true liquid nitrogen temperatures for long-term preservation. Unlike larger institutional cryogenic freezers, the compact footprint makes the 3K an excellent choice for laboratories that need dedicated cryogenic storage without sacrificing valuable floor space.

Many laboratories integrate a storage system like the Taylor-Wharton 3K alongside biosafety cabinets for sterile sample preparation, controlled-rate freezers for optimized freezing protocols, ultra-low freezers for intermediate storage, and laboratory refrigerators to create a complete cryopreservation workflow.

Taylor-Wharton K Series 3K Overview

The Taylor-Wharton K Series has earned a long-standing reputation for dependable cryogenic storage and excellent vacuum performance. The 3K model is the smallest member of the K Series family and is designed for laboratories that require dependable liquid nitrogen storage without the complexity of larger autofill systems.

Its stainless steel vacuum vessel minimizes heat transfer and reduces liquid nitrogen evaporation, helping maximize holding time between fills. The compact design also makes the unit easy to position within existing laboratory layouts while providing sufficient storage capacity for growing biological collections. Because it supports both liquid- and vapor-phase storage, laboratories can configure the system to meet their preferred cryopreservation protocols.

Common Applications

The Taylor-Wharton 3K is commonly used for storing:

Stem cells
Cell lines
Embryos
Oocytes
Sperm samples
Cord blood
Bone marrow
Tissue specimens
DNA repositories
Veterinary reproductive samples
Research cell banks

Its compact size also makes it an excellent choice for laboratories establishing their first cryogenic storage program or maintaining dedicated collections for individual research groups.

Ideal Laboratory Types

The 3K is an excellent choice for:

Biotechnology companies
IVF laboratories
Fertility clinics
Veterinary reproductive facilities
Universities
Academic research laboratories
Hospitals
Clinical laboratories
Small biobanks

Laboratories requiring dependable cryogenic storage with minimal maintenance will appreciate the 3K's straightforward operation and efficient liquid nitrogen performance.

Why Choose a Compact Cryogenic Storage System?

While ultra-low freezers provide dependable storage at -80°C to -86°C, certain biological materials benefit from storage at liquid nitrogen temperatures approaching -196°C. A compact cryogenic storage system like the Taylor-Wharton 3K allows laboratories to achieve those temperatures without investing in a large institutional storage system.

Its relatively small footprint, low evaporation rate, and efficient vacuum insulation make it particularly attractive for laboratories with modest sample volumes or satellite research facilities.

Typical Stored Materials

The Taylor-Wharton 3K is commonly used to preserve stem cells, embryos, reproductive specimens, cord blood, tissue samples, DNA libraries, research cell lines, and other biological materials requiring long-term cryogenic preservation.

Operating Costs & Energy Considerations

Because the Taylor-Wharton 3K does not use compressors or mechanical refrigeration, operating costs are determined primarily by liquid nitrogen consumption. The high-performance vacuum insulation minimizes evaporation and helps maximize the interval between fills, reducing operating costs while maintaining dependable cryogenic storage temperatures. Routine maintenance primarily consists of monitoring liquid nitrogen levels, protecting the vacuum vessel from physical damage, and following recommended cryogenic safety procedures.

Refurbishment & Testing Process

Every Taylor-Wharton K Series 3K received by American Instrument Exchange undergoes a comprehensive inspection before shipment. Our technicians inspect the vacuum vessel, neck assembly, lid, and overall cabinet condition before filling the vessel with liquid nitrogen and monitoring evaporation performance to verify acceptable vacuum integrity. Each unit is thoroughly cleaned before shipment.

Laboratories building complete cryopreservation facilities frequently purchase biosafety cabinets, controlled-rate freezers, ultra-low freezers, laboratory refrigerators, and centrifuges from American Instrument Exchange.

Shipping & Installation Considerations

The Taylor-Wharton 3K ships by freight from American Instrument Exchange. Before installation, laboratories should verify access to a reliable liquid nitrogen supply and establish appropriate cryogenic safety procedures, including adequate room ventilation, personal protective equipment, and routine liquid nitrogen level monitoring. Its compact size also makes it easy to relocate within a laboratory as storage needs evolve.
