FILTER UNITS STERICUP

with 75mm NYLON membrane and receiver flask

BRAND : LABSUPPLY

DESCRIPTION

The Stericup vacuum filtration system combines a Steritop filter unit with a receiver flask for processing and storing volumes from 150 mL to 1,000 mL.  Please see our other listings for other brand and capacities of vacuum filter units
It′s new no tip-easy grip flask design and compact profile improve stability during filtration, make gripping the receiver easier, and make Stericup filter units ideal to use in laminar flow hoods.

As an added convenience, the bottom of the receiver flask is slightly recessed, enabling capped flasks to be stacked for convenient storage. Durapore® membranes made with Polyvinylidene fluoride (PVDF) provide high flow rates and throughput, low extractable and broad chemical compatibility.

OVERVIEW

Upper Chamber

• Separates from receiver for easy access to filtrate
• Clearly marked with pore size, membrane type, catalog number, lot number and expiration date (except 115mL size) for traceability

Receiver Bottle

• Leakproof† screw cap eliminates pH shift in receiver to ensure longer life of stored fluids
• An ideal filtrate storage vessel

Nylon Membrane

• Low extractables and naturally hydrophilic
• Contains no wetting agents and is alcohol resistant
• Red collar for easy identification of correct membrane for your application

Other Features

• Padless membrane support minimizes foaming of proteinaceous samples
Non-pyrogenic and non-cytotoxic
Gamma radiation sterilized and individually bagged for a 5-year sterile shelf life

Includes:

Polystyrene cover; graduated upper chamber and storage bottle; integral membrane filter; cellulosic-plugged side arm; quick-disconnect tubing adapter.

Warning:

It is common for the polystyrene lower chamber of all brands of filter units (Millipore Stericup, Nalgene Rapid Flow Units and Pall Corporation Acrovac Units) to crack under moderate vacuum pressure.  Industry response to this issue, is to replace the lower chamber with a glass media bottle with a GL45 screw-threaded neck onto which the upper chamber will attach, giving a gas-tight connection.  Of course, the sterile integrity of the unit will be somewhat compromised with this altered arrangement.
