冷却ロ過して and ロ液

Non-PRO 日本語 から 英語 その他 化学、化学工学
従来、このような油脂中からそれに含まれるトコフェロール類やトコトリエノール類を単離するたみには、油脂をケン化あるいはメチル又はエチルエステル化した後、得られた不ケン化物あるいはエステル化物をアセトン又はメタノール溶液として冷却ロ過してステロイド類を分離し、次いでロ液から溶媒を除去したのち真空蒸留して脂肪酸あるいは脂肪酸エステル類を分離し、さらに分子蒸留してトコフェノール類又はトコトリエノール類を製取することが行なわれている。

It appears like the katakana ロ in ロ過して. can somebody help me what it is? Hope you understand with the full sentence I provided.
Votes to reclassify question as PRO/non-PRO:

PRO (2): Steven Smith, KathyT

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.

How to tell the difference between "easy" and "pro" questions:

An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)

A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).

Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.

When deciding between easy and pro, err on the side of pro. Most questions will be pro.

* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

濾過 and 濾液

I think this is just 濾過 (ろか) with katakana 濾. This means filtration. 濾液is filtrate, (noun, not verb),
