Laboratory Seating
Brewer laboratory stools are built for bench scientists, research technicians, and lab professionals who need stable, hygienic, and ergonomic seating for extended seated work. The 21520B and 21521B Ergonomic Laboratory Stools feature a contoured seat designed to promote healthy posture during sustained microscope work, pipetting, documentation, and other bench tasks that keep lab professionals seated for hours at a time. The 21521B rolls on casters for mobility between stations; the 21520B uses glides for a stationary, stable work platform. For applications that require occasional back support, the 360-Degree Round Stool with Backrest provides a flexible option. All Brewer laboratory stools are made in the USA and backed by a minimum 5-year warranty.
Laboratory Stool FAQs
What is the difference between the 21520B and 21521B laboratory stools?
The 21520B and 21521B are otherwise identical Brewer ergonomic laboratory stools. The primary difference is the base: the 21520B uses glides, which keep the stool stationary on the floor, while the 21521B uses casters for mobility. If your workflow requires moving between workstations, the 21521B is the better choice. For a fixed bench position where stability is the priority, the 21520B is preferred.
Are Brewer lab stools suitable for cleanroom environments?
Brewer laboratory stools are designed for standard lab environments. For cleanroom-specific requirements, including static control, particle counts, or specific chemical resistance certifications, contact Brewer customer service at 1-800-558-8777 to discuss whether a particular model meets your facility's cleanroom standards.
What is the seat height range on the Brewer laboratory stools?
Specific seat height adjustment ranges are listed on each product detail page. Brewer laboratory stools use a pneumatic height adjustment cylinder so seat height can be dialed in precisely to the user and workstation.
