T332

With o-ring seal screw cap and attachment loop

The o-ring secured in the top of the cap ensures a positive leakproof seal, keeping the integrity of small samples under even the most adverse conditions. This series of tubes is also available either plain or with printed graduations and white marking area for sample identification. Caps with attachment loops allow them to remain attached to the tube in order to prevent mix-up and contamination. Perfect for cryogenic work. Can withstand temperatures from -196ºC to 121ºC. Non-skirted tubes can be centrifuges up to 17,000xg.

Volume:	0.5mL to 2mL
Perfect for cryogenic work.

T334

With o-ring seal screw cap

Similar to the T332 Series but without the “tethered cap” feature. Caps without attachment loops are designed for users who prefer to remove the cap completely from the tube when filling or sampling.

T335

With o-ring seal and flat screw cap

This series of tubes is available either plain or with printed graduations and white marking area for sample identification. Tubes can be autoclaved to 121ºC in upright position with caps loosened. They also can be centrifuged up to 17,000g.

All tubes are gamma irradiated and packaged in tamperproof resealable bags to protect remaining tubes from contamination. They are identified in the list with an "S" after the catalog number. Sterile tubes are also available with printed graduations and white marking area for sample identification. They are identified in the list with an "SPR" after the catalog number.

T335TP

With o-ring seal and flat screw cap

A TAMPERPROOF microcentrifuge tube that incorporates all the features and benefits of the Simport Micrewtube Family. Ideal for all applications requiring a tamper evident seal, a Simport tamperproof Micrewtube® also has a multitude of benefits when used in your lab. It is ideal for freezer storage, boiling applications, centrifugation etc., and will fit most standard microcentrifuge rotors.

Simply screw the cap on the tube and the tamper evident sealing ring is automatically in place. When unscrewed, the ring is detached from the tube and remains in its position, showing clearly that the tube was opened. The flat cap facilitates manipulation especially in aseptic procedures. It does not incorporate an attachment loop for users who prefer to remove it completely from the tube when filling or sampling. The o-ring secured in the cap ensures a positive leak-proof seal, time after time, keeping the integrity of small samples under even the most adverse conditions.

The tamperproof Micrewtube is available in all kinds of sterile and non-sterile configurations. The tubes are available non-printed or printed with graduations and white marking area for sample identification. They also can be centrifuged up to 17,000xg. All tubes are gamma irradiated and packaged in tamperproof resealable bags to protect remaining tubes from contamination. Sterile tubes are also available with printed graduations and white marking area for sample identification. Tubes and caps are also available separately.

T336

With lip seal screw cap and attachment loop

The flexible sealing lip inside the cap ensures a positive leakproof seal under even the most adverse conditions. This deep internal lip fits snugly against the interior wall of the tube preventing the contents from coming in contact with the threads, thus reducing the chances of sample contamination.

This series of tubes is available either plain or with printed graduations and white marking area for sample identification. Caps are supplied with attachment loops in order to prevent contamination and mix-up. Cannot be autoclaved since closure is made of high density polyethylene.

All tubes are gamma irradiated and packaged in tamperproof resealable bags to protect remaining tubes from contamination. They are identified in the list with an "S" after the catalog number. Sterile tubes are also available with printed graduations and white marking area for sample identification. They are identified in the list with an "SPR" after the catalog number.

T338

With lip seal screw cap

Similar to T336 Series without the “tethered cap” feature. The flexible sealing lip inside the cap ensures a positive leakproof seal under even the most adverse conditions. This deep internal lip fits snugly against the interior wall of the tube preventing the contents from coming in contact with the threads, thus reducing the chances of sample contamination.

This series of tubes is available either plain or with printed graduations and white marking area for sample identification. The caps do not have the attachment loops for users who prefer to remove the caps completely from the tubes when filling or sampling. Cannot be autoclaved since closure is made of high density polyethylene.

T339

With lip seal and flat screw cap

This series of tubes is available either plain or with printed graduations and white marking area for sample identification. Lip seal screw caps are unattached but incorporate a flat top which provides a writing surface. These flat surfaced tubes can also be used with automatic capping machines and in packaging industries. Closures are supplied in natural color.

Tubes are made of polypropylene while polyethylene caps are easy to screw on and off. More economical than T335 Series O-ring seal model. Cannot be autoclaved since closure is made of high density polyethylene.

All tubes are gamma irradiated and packaged in tamperproof resealable bags to protect remaining tubes from contamination. They are identified in the list with an "S" after the catalog number. Sterile tubes are also available with printed graduations and white marking area for sample identification. They are identified in the list with an "SPR" after the catalog number.

T341 Series

For your special needs, the T341 Series of tubes only are either plain or printed graduations and are provided with a white marking area for sample identification.

T341T

MICREWTUBE® Tubes Only

Made of polypropylene, these tubes can be used at extreme temperatures –
from -196°C to +121°C

T341TPR

MICREWTUBE® Graduated Tubes Only

For your special needs, these tubes are identical to the T341T but are graduated and are provided with a white marking area for sample identification.

T341TBR

MICREWTUBE® Tubes Only for Light Sensitive Material

These ungraduated tubes are identical to the T341T tubes but their dark brown colour allows them to be used when storing light-sensitive material.

T341TLST

MICREWTUBE® Tubes with Low Adhesion Surface

With all the advantages of the T341T series, the specially formulated polypropylene used to manufacture these tubes provides a low adhesion surface to obtain maximum sample yield. Ideal for research procedures such as nucleic acid amplifications, protein work and others. No lubricants (such as silicone) necessary, thereby eliminating the danger of sample contamination.
