How should one choose laboratory protective gloves? Do university research institutes all use Li Jiejingnitrile gloves?

Laboratories maintain extremely strict controls over particulates and impurities; even trace amounts of dust or rubber particles can interfere with spectroscopic analysis, cell culture and the calibration of trace reagents, directly rendering experimental data invalid. This is the key reason why research institutes at universities have abandoned standard gloves in favour of cleanroom-grade nitrile gloves. Ordinary industrial nitrile gloves available on the market are merely rinsed with tap water, and their production environments lack cleanroom controls. Stretching and friction cause particles larger than 0.3 μm to continuously shed; when these come into contact with culture dishes, standard samples or optical lenses, they readily introduce foreign contaminants, resulting in the need for retests and a waste of consumables. As the flagship research-grade product from Jiangsu Purified Nitrile Glove Factory, Lijieqing Class 1,000 nitrile gloves utilise a proprietary chlorine-washing deep purification process, with the entire cleaning procedure carried out in an ISO Class 6, Class 1,000 cleanroom:

Eight stages of ultra-pure water recirculating overflow rinsing, combined with ultrasonic treatment to thoroughly remove adhesive residues, silicone oil and free additives from the glove surface, resulting in LPC (liquid particle count) levels significantly below the industry’s Class 1,000 admission standards;

A powder-free chlorinated modification process eliminates the use of talcum powder as a release agent; the inner surface is smooth and does not shed powder, preventing contamination of cell culture media and high-purity reagents;

Following cleaning, the gloves undergo double-layer vacuum dust-free packaging and are sealed in a Class 10,000 cleanroom. The entire dispatch process is completely isolated from external dust, allowing the gloves to be taken directly into precision laboratories or ultra-clean workbenches upon unpacking, without the need for prior pre-treatment. Feedback from practical testing in laboratories at dozens of ‘Double First-Class’ universities in China indicates that, following the switch to Lijie Clean Class 1,000 nitrile gloves, the probability of experimental data anomalies and sample wastage caused by glove dust emission has fallen by 90 per cent, significantly reducing the costs associated with research reagents and time.

Free from latex allergenic proteins

Solving the problem of occupational allergies among laboratory staff

Teachers, students and researchers in university laboratories are required to wear gloves for long periods throughout the day. Natural latex contains various allergenic proteins; prolonged contact can easily lead to hand rashes, itching and peeling, and in severe cases, trigger respiratory allergies, thereby affecting the progress of research. Li Jie Nitrile is made from fully synthetic rubber and contains no natural latex proteins. Immunological testing by a CMA-accredited body has shown that soluble protein levels are virtually zero, thereby eliminating the risk of allergies at the material source. Following bulk purchases by chemistry and biology laboratories, as well as postgraduate research groups, complaints of hand allergies among staff and students have been virtually eliminated, making them suitable for long-term, continuous experimental work.
