Overview

Insterprep® is a range of instantly soluble, sterile, granulated media specifically designed to speed up and simplify sample preparation for microbiological analysis.

Insterprep media comes in two forms:

  • Insterprep media bags - Instantly soluble, pre-measured, sterile media in a Stomacher® bag. Simply add sterile distilled water and your sample as per your protocol.
  • Insterprep sachets - Instantly soluble, sterile media granules, ready to use. Just add to your own Stomacher® bags. Choose the Insterprep sachet that fits your protocol needs.

Three types of media are available:

  • Buffered Peptone Water - A pre-enrichment medium for increasing the recovery of injured Salmonella species from foods prior to selective enrichment and isolation. The composition and performance criteria of this medium are as per the applications laid down in ISO 6579-2002. 100 bags or sachets per pack.
  • Fraser Broth - Recommended for the selective enrichment of Listeria species from food. 50 bags or sachets per pack.

Insterprep media is available in 225 ml bag or sachet formulations for the Stomacher 400 Circulator or in 3375 ml (Peptone Water or Max Recovery Diluent) or 1125 ml (Fraser Broth) sachet formulations for the Stomacher 3500

These are very comfortable, after few sleeps since I got them, they haven't got flat at all, they are really good looking, retain shape well even inside a pillow case, they fit perfect on queen size pillow cases, and they dont get hot while asleep.

A nice comfy pillow.
Team Name: Pack of 2, Size: Queen - 20" x 30", Color: Blue Edge
A Recently had a pillow that broke and needed a new one. I love this pillows firmness. This pillow is expensive just for one, but I gave the other pillow to my brother as I thought if one of his pillows falls apart, he has one too. I’m not sure how durable this pillow is, but it looks pretty sturdy. It does get flat within 3 weeks after opening. It does not cool.

Fluffy, Supportive, and Perfect for a Great Night’s Sleep
Team Name: Pack of 2, Size: Queen - 20" x 30", Color: White
I purchased the Premium Queen Size Pillow set of two on a flash deal, and I’m so glad I did! These pillows have the perfect balance of softness, thickness, and firmness. At about nine inches thick when fluffed, they easily compress down to about three inches, thanks to the down alternative fill. This makes them incredibly supportive without pushing my neck up too high. The down alternative filling gives just the right amount of “nestle,” letting my head and neck sink in comfortably, which has improved my sleep quality tremendously. They’re fluffy yet still provide that soft firm support I love. Another big plus is washability. I can toss them in the wash, and they come out looking and feeling like new. For a 2-pack, they’re a fantastic value for money, and I would purchase them again.

Premium Pillows
Team Name: Pack of 2, Size: Queen - 20" x 30", Color: White
Purchase these as a gift for1 of my children that had terrible pillows. To say she was pleased would be an understatement. She said that these were some of the softest and most comfortable pillows she had ever used. They remained puffy while conforming comfortably to her sleep style. She was absolutely in love and I would definitely purchase again.
