Our Series of Customized Products
Laboratory chairs with armrest
Besides endowing the integrated integrated foam (PU) with anti-fouling and anti-bacterial properties, we offer custom services tailored to lab-specific requirements.
The height and tilt backrest of the seat can be customized according to the needs of users to adapt to the various postures and operation requirements of users in different experimental activities.
The appearance of the product can be customized according to the customer's drawings to ensure that the design conforms to the overall style of the laboratory and prevents any possibility of pinching or crushing injuries to improve safety.
For chairs with seat height adjustment exceeding 650 mm, additional anti-slip steps can be provided to enhance the safety and convenience of users.
Chairs with seat height exceeding 650 mm are usually not equipped with casters, but foot spikes can be selected to increase stability and safety.
The chassis adjustment function of the seat can be customized according to the specific needs or usage scenarios of customers to ensure that the chair can adapt to different working environments and operation requirements.
Laboratory chairs with armless
The armless design is more streamlined, reducing gaps and dead corners, meeting cleanroom and anti-contamination requirements.
Streamlined armless design (width ≤50cm) for tight spaces. Seat depth customizable (40-50cm) with 10° forward tilt or flat profile to reduce knee pressure.
Materials: antibacterial PU (silver-ion additive, 99.9% microbial reduction), electropolished 304 stainless steel, or ESD PVC. Seams welded seamlessly (gap ≤0.2mm).
Options: silent swivel casters (with brakes) or floor-mounted bolts (300kg load-bearing). Anti-winding casters available for bio labs with hair debris.
PU passes ASTM D543 chemical resistance test (20+ reagents including HCl and ethanol). Metal frames Teflon-coated (100℃ heat-resistant).
ESD-compliant (10^6-10^9Ω, ANSI/ESD STM11.11 certified). Optional side tool racks (3kg load) or anti-stain PVC document pouches.
Laboratory Stools
With years of experience, we provide a variety of customized services according to the special needs of different laboratory environment.
Adjustable height via pneumatic lift (15cm range) or fixed weldment (±0.5cm tolerance), ergonomically matched to lab bench heights (70-90cm)
Materials include 316L stainless steel (chemical-resistant), ESD-certified PP, or antibacterial PU (ISO 22196 compliant). Finishes: electropolished (Ra≤0.8μm) or Teflon-coated (non-stick).
Choose between silent PU casters (with brakes) or stationary bases. Optional silicone suction cups (200kg load-bearing) or heat-resistant non-slip pads (autoclavable at 121℃).
Ergonomic upgrades: contoured seat (pressure-dispersing), adjustable lumbar support (±15° tilt), anti-fatigue footrest (5cm height adjustment)—OSHA-compliant for prolonged use.
Cleanroom-certified (ISO 14644 Class 5): fully welded construction (no exposed screws), gap ≤0.3mm, validated for H2O2 fumigation (log6 kill rate)

Our SGS Certifictions and Innovation Patents
As the world's leading inspection, identification, testing and certification organization, SGS's certification is highly authoritative. After strict testing by SGS, the Polyurethane Clear Protective Film technology has excellent performance in antibacterial properties, wear resistance, temperature resistance, transparency retention and other aspects, which fully proves the reliability and advancement of the technology.
HEWEI polyurethane transparent protective film uses advanced polyurethane materials, which have a unique molecular structure and give the protective film many excellent properties. The high strength and flexibility of polyurethane materials enable it to effectively resist various external impacts. At the same time, it also has excellent wear resistance, which can maintain the integrity of the protective film for a long time and provide lasting protection for the protected objects.
The antibacterial polyurethane cushion material independently developed by Hewei Technology officially passed the national invention patent certification on August 28, 2018, and the patent number is CN104892893B. This invention patent certificate was issued by the State Intellectual Property Office of the People's Republic of China. It is not only a high recognition of the innovative wisdom of Hewei scientific research team, but also a strong proof of Hewei deep technical background in the field of material research and development. This patent achievement makes Hewei stand out in the cushion material market and establishes its leading position in technology.
The test results show that the cushion material has a significant inhibitory effect on common pathogens such as Klebsiella pneumoniae, Escherichia coli, and Staphylococcus aureus. It can be clearly seen from the comparative test chart that the growth of bacteria in the sample area containing antibacterial agents is effectively controlled, while the areas without antibacterial agents are multiplied by bacteria. This fully shows that the use of Hewei antibacterial polyurethane cushion materials can effectively reduce bacterial growth and provide users with a healthier and cleaner sitting experience.
