VWR 一次性取樣勺

詳細(xì)介紹

一次性樣品杓:

一次性樣品勺，為多用途、堅(jiān)固和經(jīng)濟(jì)的工具，可用于收集、轉(zhuǎn)移和處理化學(xué)和生物樣品。

耐稀酸和堿
能減少交叉污染
可進(jìn)行高溫高壓無(wú)菌
符合FDA食物接觸應(yīng)用類標(biāo)準(zhǔn)
經(jīng)濟(jì)型樣品杓生產(chǎn)時(shí)所用添加劑，有助于促進(jìn)PP樹(shù)脂的生物降解

這些樣品杓形狀新穎，可用作鏟、匙、勺、刮刀、攪拌棒或擦拭工具，是回收經(jīng)液氮冷凍的樣品的理想工具。標(biāo)準(zhǔn)樣品杓一端是獨(dú)特的鏟/勺端，另一端是小勺端。一次性大型樣品杓比一次性標(biāo)準(zhǔn)樣品杓大50%。長(zhǎng)柄便于從大的容器中提取材料。抗靜電微樣品杓具有兩個(gè)V形鋒利，是操作微量材料的理想選擇。

VWR Disposable Polypropylene Spatulas

Economical, Polypropylene, Single-Use Laboratory Spatulas
Ideal for Transferring, Manipulating, and Mixing Materials
Versatile Double-Ended Design
Help Minimize Cross Contamination

Autoclavable

Economical, disposable tools for transferring, collecting, and handling chemical and biological materials. Versatile double-ended design enables use as a spatula, spoon, scoop, scraper, stirring rod, or man. The unique hollow core minimizes thermal transfer for effective collection of liquid nitrogen frozen samples. Virgin polypropylene construction is resistant to dilute acids and bases. Autoclavable.

Antistatic micro spatula features two V-shaped, sharpened tip ends and is ideal for manipulating extremely small volumes of material. Standard spatulas feature a unique spatula/spoon end and a smaller scoop end. Macro spatula is 50% larger than the standard spatula and features a spatula/spoon end and a clump-busting pick end. The long shaft of the macro spatula eases access to material in larger containers.

ECO spatulas are produced with an additive that helps promote biodegradation in the polypropylene resin. Spatulas produced using this additive were found to biodegrade an average of 20% in the first 271 days of testing.

Biodegradation rates of ECO spatulas were measured according to the ASTM D5511 test method. Tests were conducted using 48% solids content; solids content in naturally wetter landfills range from 55% to 65%, while the driest landfills may reach 93%. Actual biodegradation rates will vary in biologically-active landfills according the solids content, temperature, and moisture levels of the landfill.
