A kit containing vials, ampoule and broth bag to assess operator technique

Redipor® Universal Operator Broth Transfer Kit

The Redipor® Operator Broth Test Kit is a pre-packaged set of components; created in accordance with guidance from the UK Pharmaceutical Aseptic Services Committee; to aid in the assessment of operators undertaking aseptic preparations.

Used in high level cleanroom environments as a standard assessment of an operator's ability to maintain the sterility of materials during the preparation of aseptically prepared injectable dose forms, and for routine operator monitoring.

The kit contains: a 50ml Tryptic Soy Broth (TSB) injection vial; three empty 30ml sterile injection vials; a 100ml TSB broth bag and one 10ml TSB ampoule.  

The EVA infusion bag is particularly appropriate to TPN compounding.  All components are supplied by Cherwell Laboratories in a purposefully designed corrugated plastic box, for ease of use.

Asked Questions

What does the use by date mean on Redipor® prepared media?

For Redipor media the Use By date is the last day on which the medium should be inoculated or exposed. Any incubation period that is normal for that product may begin on that day. For example a 14 day sterility test in TSB or a 5 day incubation for a TSA settle plate.

Do I need to store my prepared media in the fridge?

The majority of our prepared media can be stored in ambient conditions, not exceeding 25ºC. There are only a small number of very specialist products that require different storage conditions.

We have never specified refrigeration as a storage condition for our general media as this causes excess condensation and can result in very wet agar, rendering it impossible to use.

We need a specific or bespoke media type. Can Cherwell help?

Our Redipor Prepared Media range is so extensive that not every product is included in the official price list. In addition to offering such a wide selection of products, we have developed a flexible manufacturing process enabling us to produce bespoke solutions.
