Syringe filters
Syringeless filters Mini-UniPrep™
The Whatman Mini-UniPrep™ filter provides a quick and easy means of removing particles from HPLC samples. In comparison to other methods the amount of time required for sample preparation is reduced to one third. Mini-Uni-Prep™ is a ready-to-use filter unit consisting of a 0.4ml chamber and a plunger. The plunger contains a filtration membrane at one end and a cap with septum at the other. The plunger is pressed through the sample in the chamber. The pressure generated forces the filtrate into the plunger reservoir, with air escaping through the vent hole until the locking mechanism engages to form an airtight seal. The unit can now be placed in any autosampler and the sample analysed....
Syringeless filters, amber Mini-UniPrep™
Amber colorant prevents photo degradation of light sensitive samples. Same colorant used in pharmaceutical containers designed to meet USP specifications for light resistance. Translucent amber chamber and plunger enable easy visual inspection...
Syringeless filters, Autovial™
Provides a single disposable, manual pressure filtration system which is fast and easy to use in sample preparation.
- Built-in pre-filter for "difficult" samples
- Minimal waste
Syringeless filters, slit septa Mini-UniPrep™
Slit septum cap enables Mini-UniPrep use with current robotics on HPLC instruments for high throughput automation
Durable yet flexible slit septum cap has been specially designed for instruments with sensitive sampling needs. Sample evaporation is minimal....
Syringeless filters, UniPrep™
Comprise a 5ml capacity, medical grade polypropylene test tube which initially holds the sample, and hollow plunger incorporating a filter at the tip. In use the sample is manually pressure filtered into the plunger which then acts as a storage vial for the filtered sample. The plunger has a removable cap. Non-sterile....
Millex® Syringe Filter, PES, 33 mm
The Millex® Syringe Filter has been specially manufactured for sterilization or clarification of biological solutions. To increase throughput and flow rate, the filter has a larger filtration surface. This also reduces the pressure required to emtpy the syringe. The filters are provided with a quality certification because they are manufactured under a controlled environment and an automated process....
