The Only Hand-Tight Column Protection for UHPLC

Sigma-Aldrich™ introduced a new range of OPTI-SOLV EXP Pre-Column Filters (from Optimise Technologies, Inc). The OPTI-SOLV EXP hand-tight Pre-Column Filter for extreme high-pressure applications. OPTI-SOLV EXP is ideal for protecting columns with small particle size material employing ultra high-pressure techniques such as UHPLC.

Such techniques analyse samples in the most demanding applications, which can decrease the life of these expensive columns. EXP Pre-Column Filters help extend that life and protect users column investment, without sacrificing performance. The filters are approved for use at 20,000 psi and tested up to 30,000 psi.

EXP Pre-Column Filters are available with Titanium Hybrid ferrules for easy direct connection to any UHPLC column. The filter comes as a complete package including fittings to provide repeated tube stop and zero dead

volume column connections. The fittings allow them to be easily interchangeable with the OPTI-SOLV EXP guard columns and the hand-tight filter replacement means no additional tools are required.
