Unigloves Cobalt Pearl Nitrile Gloves, Cobalt, Powder-free, Size L, GP1014

Anyone who has to use a tablet, smartphone or barcode scanner from time to time whilst working in a laboratory or at reception will be familiar with the problem: taking off your gloves, using the device, putting them back on, several times an hour. According to the manufacturer, Unigloves Cobalt Pearl nitrile gloves are touchscreen-compatible, meaning that screens can be operated whilst wearing the gloves. These powder-free, latex-free gloves, made from fully dipped nitrile, come in a rich cobalt blue, with textured fingertips for a secure grip and a rolled cuff that makes them easier to slip on. They are sold in a box of 1,000, divided into 10 boxes of 100 each, in five sizes from XS to XL.

Latex-free, thiuram-free and protein-free

As gloves made entirely from nitrile, the Cobalt Pearl are completely latex-free and, according to the manufacturer, are also thiuram-free and protein-free. This makes them a suitable choice for staff who need to take into account allergies to natural latex or sensitisation to vulcanisation accelerators (thiurams). According to the data sheet, the palm has a thickness of 0.09 ± 0.03 mm, measured as a single layer in the centre of the palm. The median tear strength is at least 6.0 N, both before and after artificial ageing.

Touchscreen-compatible: operate devices without changing gloves

According to the manufacturer, Cobalt Pearl allows you to operate a mobile phone or tablet screen without taking off your gloves. This is particularly useful wherever digital documentation, scanning or communication is required whilst working, such as when recording samples in a laboratory, scanning batches in food processing, or documenting procedures at a treatment station. This eliminates the need to change gloves and reduces the risk of contaminated gloves being reused for screen work without realising it, as the devices can be operated directly through the work gloves.

Chemical protection in accordance with EN 374, Category III, Type C

Cobalt Pearl is certified as a chemical-protective glove in accordance with EN ISO 374-1, Category III, Type C, and also provides protection against viruses, fungi and bacteria in accordance with EN ISO 374-5. A permeation level of 6 was determined for 40 per cent caustic soda in accordance with EN 374-4, with a degradation rate of minus 5.3 per cent. For other chemicals, the manufacturer’s product-specific chemical resistance table applies.

Certified to EN 455 and PPE Category III

Cobalt Pearl complies with EN 455 (Parts 1 to 4) for medical single-use gloves and is manufactured under a quality management system certified to DIN EN ISO 13485:2021. The type examination was carried out in accordance with Module B and Module C2 of the PPE Regulation (EU) 2016/425 by the notified body CCQS (No. 2834); this combination of modules is intended exclusively for the highest PPE Category III. An AQL value of 1.5 applies in the 1,000 ml water-tightness test; furthermore, the glove is food-safe.

Choosing the right size

The manufacturer also assigns a numerical glove size to each Cobalt Pearl ready-to-wear size, ranging from 5 to 6 for XS to 9 to 10 for XL.

Cobalt in the twelve-piece Pearl range

Cobalt Pearl is one of twelve colours in the Unigloves Pearl range available from LT Laborhandel and should not be confused with the lighter Blue Pearl, which is a separate colour with its own data sheet. Those looking for a dark contrasting colour for cleanliness checks will find it in Black Pearl, whilst those preferring a neutral standard colour for general wards will find it in Green Pearl. All colours share the same basic construction of fully dipped nitrile with textured fingertips, a rolled cuff and certification to EN ISO 374-1 Category III Type C. According to the manufacturer, touchscreen compatibility is specifically documented for Cobalt Pearl.

Use, storage and disposal

We can provide storage conditions and shelf life on request. Regarding handling, the manufacturer states that this is a non-sterile, single-use glove that can be worn on either hand.

As a practical guideline based on everyday laboratory practice, rather than manufacturer’s specifications: nitrile gloves such as Cobalt Pearl are usually changed for each task or process step, but at the latest at the first visible sign of damage, soiling or contact with chemicals outside the tested application. After use, they are generally disposed of as operational waste, whilst contaminated gloves are disposed of separately in accordance with internal hazardous substances regulations.

Typical applications

The touchscreen compatibility makes Cobalt Pearl particularly suitable where digital devices form part of the workflow:

• Laboratories with digital sample recording or tablet-based documentation at the workplace
• Food processing with barcode or batch scanners, thanks to food-grade certification
• Medical and dental practices with digital patient documentation at the treatment station
• Facilities using multiple Unigloves Pearl colours, where Cobalt is specifically used for colour-coding individual stations or process steps

Wherever a glove change would otherwise be necessary for every brief interaction with a screen, Cobalt Pearl’s touchscreen compatibility reduces the effort involved without compromising on protective performance or certification.

Assessing requirements correctly: from the carton to the digital workplace

The box of 1,000 gloves is divided into 10 boxes of 100 each, so that individual boxes can be made available independently of one another at different workstations. For a workstation with digital documentation and an assumed consumption of 15 gloves per day (changed when switching tasks or samples), one box of 100 covers approximately 6 to 7 working days; a whole carton covers around 13 working weeks. Where there are several digitally equipped workstations, this calculation can be multiplied by the number of workstations to estimate the total requirement for a specific period. Sales are exclusively by the full carton; a single box of 100 cannot be selected separately during the ordering process.

Frequently asked questions about the 1,000-piece carton

Does the touchscreen really work with every device?
The manufacturer generally describes the touchscreen functionality as being suitable for mobile phone and tablet displays. We can provide details on compatibility with individual device models or specific film displays on request.

Is Cobalt Pearl latex-free and suitable for people with allergies?
Yes. The glove is made entirely of nitrile and, according to the manufacturer, is latex-free, thiuram-free and protein-free.

How resistant is the glove to chemicals?
The data sheet lists a test chemical with numerical values: 40 per cent caustic soda with a permeation level of 6 and a degradation rate of minus 5.3 per cent. We can provide the breakthrough time in minutes on request.

Is Cobalt Pearl the same as Blue Pearl?
No, they are two distinct colours, each with its own data sheet and manufacturer’s item number; Cobalt is a darker, richer blue than the classic Blue Pearl.

How do I find the right size?
Either by the numerical glove size (XS 5-6 to XL 9-10) or by the width in millimetres; see the size chart above.

Can I order quantities smaller than a 1,000-piece carton?
No, the sales unit is the carton of 1,000 pieces, divided into 10 boxes of 100 pieces each.
