Description
BOLA grip collar sleeves 45/50 PTFE are PTFE ground-joint sleeves designed for high-vacuum-tight sealing of laboratory glassware. Manufactured from polytetrafluoroethylene, they feature a protruding grip collar and sealing rings on the outer surface, delivering a low leak rate of less than 1 × 0,0001 mbar × l × s/1. The robust build supports continuous use, while the accessible sealing rings simplify cleaning between runs. Dimensions follow US standard size 45/50. Supplied as 1 piece with a net weight of 0,015 kg, the sleeve provides a durable, grease-free interface for larger ground joints in vacuum systems, distillation trains, and reaction setups. These sleeves from manufacturer Bohlender combine chemical resistance of PTFE with a practical collar for secure handling during fitting and removal. Ideal where stable sealing performance, easy maintenance, and reliable mechanical contact on standard joints are essential in everyday laboratory practice.

Questions about BOLA Sleeves with Gripping Ring, 45/50 PTFE
What is this article?
BOLA Sleeves with Gripping Ring, 45/50 PTFE is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Disposable coveralls & gowns, inside Protective clothing & workwear, in Lab safety equipment.
A coverall or a gown covers more of the body than a coat. The type rating, where one is claimed, describes the kind of hazard the fabric was tested against. A visitor's thin gown and a chemical protective coverall are different products. Seams and the hood are part of the rating.
Workwear is the layer between the person and the room. A lab coat is the ordinary coat. A coverall is what is worn when the coat does not cover enough. Cleanroom garments are about the particles the person sheds, not only about the splash. Radiation and hearing protection are specific physical hazards with their own ratings. The rating, not the colour, is the specification. Equipment placed on the EU market follows the PPE Regulation. Practice is at EU-OSHA on dangerous substances.
