bimos ESD Labsit work chair with castors, seat height 450 to 650 mm, black Skintec, 9123E-4000-3218

The bimos ESD Labsit is a work chair with a flexible backrest for workstations in electrostatic protected areas (EPAs), in the laboratory as well as in production. According to the ESD declaration from bimos, the ESD Labsit series meets the requirements of DIN EN 61340-5-1 and ANSI/ESD S20.20-2021 for use in EPAs. There are three versions, which differ in seat height and floor contact: with castors, with glides and foot ring, or with seat-stop castors and foot ring. The seat is available in various ESD upholstery options. Upholstery and seat shell are black; the star base made of polished aluminium is part of the standard equipment on all versions.

ESD properties according to the manufacturer’s specification

bimos states a typical resistance to groundable point (Rgp) of 10⁵ to 10⁷ ohms for the ESD Labsit. The performance features give 10⁶ ohms as the typical value. According to the declaration, the chair can dissipate charges on persons to the conductive flooring or floor mat. As standard equipment, bimos lists volume-conductive plastics and conductively coated steel parts, and on the ESD Labsit 2 also conductive castors. The ESD declaration is a manufacturer’s declaration from bimos and not a test report from an independent test laboratory.

Flex function in the backrest and seat

The backrest is made of plastic and has a 3D flex function. According to the manufacturer, it yields when leaning back and when twisting the upper body to the side. The front edge of the seat is also flexible and gives way in a forward-leaning working posture. The backrest is 420 mm high and the seat depth is 420 mm. The seat height is adjusted steplessly by the gas spring. A handle on the backrest makes it easier to move the chair. According to the manufacturer, the load capacity is 120 kg.

Castors, glides or seat-stop castors

The ESD Labsit 2 (9123E) has soft, load-dependent braked safety twin castors for hard floors and adjusts from 450 to 650 mm. bimos recommends castors above all for places where you have to stay flexible and mobile.

The ESD Labsit 3 (9121E) ranges from 520 to 770 mm. It stands on glides made of robust, abrasion-resistant plastic and has a chrome-plated, height-adjustable foot ring. The manufacturer names glides for places where the chair has to provide support, for example for tasks requiring very high physical effort. On the ESD Labsit 4 (9125E), with 560 to 810 mm, seat-stop castors replace the glides. They lock under load and can be moved when unloaded. According to bimos, standard castors are not permitted for safety reasons above a seat height of 650 mm, whereas seat-stop castors are, and they correspond to the safety regulations of DIN 68877. For raised tables and installations where the chair stays in place, the ESD Labsit 3 is the obvious choice. Those who need to move the chair at raised workstations choose the ESD Labsit 4.

ESD upholstery options

The bimos price list shows all upholstery options as ESD versions. Duotec fabric is breathable, absorbs and releases moisture, and can be cleaned with commercially available upholstery cleaners. Magic synthetic leather is PVC-free, washable and unaffected by oils and, according to the manufacturer, also resistant to commercially available disinfectants. Skintec has a soft upholstery core and a robust, easy-care surface which, according to the manufacturer, is also resistant to commercially available disinfectants. According to bimos, this resistance has been tested. Supertec consists of a micro armour on a textile backing material which, according to the manufacturer, is cut-resistant, non-slip, breathable and easy to clean.

Hygienic Design and cleaning

The chair has a low-joint, form-fitting construction (Hygienic Design). According to the manufacturer, it can be used in laboratories of safety level S1 to S3. Which cleaning agents and disinfectants are suitable in an individual case, also with regard to the ESD property, should be clarified before use.

Typical applications

• Workstations in electrostatic protected areas (EPAs) in electronics manufacturing
• Assembly, testing and inspection stations in industry
• Laboratory workstations with electrostatically sensitive components
• Laboratories in higher education, biotechnology, chemistry and pharmaceuticals (areas of application according to bimos)
• Raised tables and installations with the ESD Labsit 3 or 4
• Places with cleaning regulations and disinfection, for example with Magic synthetic leather or Skintec

Is there proof of the ESD property?
bimos issues an ESD declaration, which you can download below. It applies to the ESD Labsit series and names the typical resistance to groundable point, but neither model numbers nor values for individual upholstery options. If you need further proof for an ESD audit, please talk to us.

Are there armrests or name clips?
bimos names armrests (9129) and the Lab-Clip (9128) as accessories for the ESD Labsit. Neither is part of the scope of delivery.
