MTC Bio Flip n Fold sterile sampling bags

Contamination-Free Collection, Start to Finish

Your sample should never touch anything but the inside of a sterile bag. Flip 'n Fold™ bags open with two external grip tabs, so fingers never enter the opening. Remove the tear strip, pull the tabs, add your sample, fold three times, and bend the wires. The bag is now airtight and moisture-sealed.

Made of virgin polyethylene for clarity and strength, every bag is sterile, RNase-free, DNase-free, and non-pyrogenic, and meets USDA, EPA, and FDA standards. That makes them a dependable choice for regulated QA and environmental programs.

Built for Real-World Sampling

Hands-Free Opening
External grip tabs open the bag without finger contact, protecting sterility.

Glove-Safe Closure
PVC tabs extend past the stainless steel wire ends, so there are no punctures, scratches, or torn gloves.

Wide Temperature Range
Rated from −210 °C to +80 °C for frozen and cold-chain samples.

Heavy-Duty 55 oz Sizes
4.0 mil film on B5910 and B5911 handles soils, sludges, and blended material.

Write-On Marking Area
A printed white panel on select sizes stays legible and resists smearing, so no tape or labels are needed.

Stores Flat
Even the 55 oz (1,600 mL) bag folds completely flat to save storage space.

Tip for a Leak-Tight Seal

Fold the top of the bag over at least three times before bending the wire tabs. Under-folding can let liquid seep out if the bag is squeezed during transport. Keep bags in their dispenser box until use to preserve sterility.

Frequently Asked Questions

Are Flip 'n Fold™ bags a good alternative to Whirl-Pak® bags?

Yes. Flip 'n Fold™ bags use the same fold-over, wire-tab closure style, come sterile, and are offered in 2 to 55 oz sizes for food, water, soil, and environmental sampling. Whirl-Pak® is a trademark of its respective owner; Blue Tiger Scientific is not affiliated.

Are Flip 'n Fold™ sampling bags sterile?

Yes. They are sterile, RNase-free, DNase-free, and non-pyrogenic, and they meet USDA, EPA, and FDA standards.

How do you seal a Flip 'n Fold™ sampling bag?

Remove the tear strip, pull the two external grip tabs to open the bag, add your sample, fold the top over at least three times, and bend the wire tabs. The bag is then airtight and moisture-sealed.

What temperature range can the bags handle?

Flip 'n Fold™ bags are suitable from −210 °C to +80 °C, so they work for frozen and cold-chain samples.

Which sampling bag size should I choose?

Use 2–4 oz bags for swabs and 100 mL water samples, 18–27 oz for typical food and environmental grab samples, and the heavy-duty 4.0 mil 55 oz bags for bulk soil, sludge, and composite samples.

Which sizes have a write-on marking area?

B5761 (4 oz), B5771 (18 oz), and B5911 (55 oz) include a printed white marking panel for labeling without tape or labels.
