PIPETTE WITH IMPROVED READABILITY AND TOUGHNESS

PIPETTE WITH IMPROVED READABILITY AND TOUGHNESS

A serological pipette has an elongated hollow tubular body having an optical transmission of 40 to 70% over a range of 390 to 700 nm. The pipette body is formed from a polymer composition that includes 5 to 30 wt.% poly(styrene-butadiene-styrene) and 70 to 95 wt.% polystyrene. The tubular body is fo...

Zusammenfassung:A serological pipette has an elongated hollow tubular body having an optical transmission of 40 to 70% over a range of 390 to 700 nm. The pipette body is formed from a polymer composition that includes 5 to 30 wt.% poly(styrene-butadiene-styrene) and 70 to 95 wt.% polystyrene. The tubular body is formed by extrusion at a barrel temperature ranging from 400 to 500F. 种血清移液管具有伸长的中空管状主体，所述伸长的中空管状主体在390至700nm范围内的透光率为40至70％。移液管主体由聚合物组合物形成，所述聚合物组合物包括5至30重量％的聚(苯乙烯-丁二烯-苯乙烯)和70至95重量％的聚苯乙烯。管状主体通过在400至500°F范围内的筒温度下挤出形成。
