Day-Impex Limited: eight decades supplying laboratories and biosecurity

Day-Impex Limited is a British manufacturer and supplier of professional biosecurity, hygiene and cryogenic products. The company was founded on 22 July 1946 by Guy Berger and his brother-in-law David Yorke, initially operating from Southend-on-Sea, Essex, and trading in imported and exported specialist glass products and electric light bulbs. Over the following decades it moved into laboratory glassware, scientific apparatus and specialist technical equipment, serving laboratories, universities, hospitals, research facilities and industrial organisations in the United Kingdom and abroad.

The company states that it operates in accordance with the ISO 9001:2015 quality management standard, a certification it presents as backing its process consistency and continual improvement. Its head office and manufacturing base is at Station Works, Earls Colne, Colchester, Essex.

Human health and infection prevention

Under its human health line, Day-Impex supplies professional-grade high-level disinfectants and skincare products formulated for laboratories and medical practices. The company describes this range as high-performance protection supplied directly from its Essex factory.

Animal health and aquaculture

The animal health division covers high-performance infection control and DEFRA-approved disinfectants intended to protect livestock and companion animals. The company positions these products for farmers and veterinarians concerned with animal welfare and operational safety. A separate aquaculture line offers Virkon Aquatic biosecurity disinfectants aimed at fisheries, fish farms and aquaculturists, with uses including protection of fish stock and maintenance of water quality. The catalogue also includes a pet hygiene and grooming section.

Cryogenic solutions and the DILVAC range

Day-Impex describes itself as the home of the DILVAC range, which it manufactures. The cryogenic catalogue is organised into several groups:

• DILVAC Dewar flasks, alongside DILVAC accessories and dry ice
• CryoLab storage and CryoLab accessories
• CryoLab cell analysis
• On-site dry ice makers and tempering beakers

The company states that these manufacturing processes are certified to ISO 9001:2015 quality standards. The cryogenic line is presented as covering storage and transportation needs.

PPE and specialist protection

A further division supplies personal protective equipment for clinical and industrial environments, from chemical-resistant gloves to high-clarity face shields. The company frames this range around cryogenic safety wear and specialist protection for environments where safety standards are demanding.

Heritage and ownership

The company traces three generations of leadership. After the founders, Graham Berger and Stuart Berger, sons of Guy Berger, took over and expanded the product portfolio and supplier relationships. Day-Impex was later acquired by David Jones and Judith Wilkins, a phase the company links to modernisation, ecommerce expansion and new product development, while maintaining its long-standing relationship with the industry leader LANXESS. The company presents its current focus as investment in cryogenic solutions and support for global health sectors. It marks its 80th anniversary across 1946–2026 and describes itself as an independent, family-led British company with international reach.
