Manufacturing expertise and quality design that understands the technical applications is as important in producing microcentrifuge tubes as it is in producing pipet tips and pipettors. Material selection, wall-thickness, cap-to-tube inter face, and thread-configuration will vary drastically depending on the specifically designed purpose and ultimate use of the tube. Within this section you will find a large variety of microcentrifuge tubes designed to meet your specific needs. Whether you require a transport vessel, a tube to withstand boiling or deep-freezing, or simply a tube whose lid can be opened easily with one hand, you will find it in this section of the catalog.
All of the HydroLogix microcentrifuge tubes in this catalog have been manufactured under the same stringent quality standards applied to our ART brand pipet tips. All tubes are cer tified RNase/DNase, RNA/DNA, ATP, and Pyrogen free, and we believe that there are no tubes better suited for the everyday rigors of the laboratory environment. We invite you to sample these tubes for free and see for yourself.

Graduated microcentrifuge tubes with safelock cap

If you are looking for a superior locking cap, MBP’s graduated microcentrifuge tubes with our exclusive ‘Safelock’ cap will become your tube of choice. These tubes feature an advanced locking system for safe and convenient centrifuging, boiling, freezing, incubation, or storage of samples for your most critical procedures. Only MBP’s ‘Safelock’ can offer the same sample security as found with regular screw-cap tubes yet maintain the same ease of use as a standard snap- cap. The cap snaps closed, then the lock easily slips into place with one simple hand operation. The larger, rounder cap design provides more thumb contact while the smooth surface reduces the possibility of ripped or punctured gloves. 

Conical and free-standing microcentrifuge tube with screw-cap & O-ring

These first-class conical microcentrifuge tubes are made from a crystal clear resin that easily allows you to view your samples. Made from the highest quality polypropylene, these tubes are suitable for vapor phase liquid nitrogen storage, boiling, and autoclaving and are sturdy enough to withstand centrifugation of 20,000 x G. External ribs on the free-standing tubes position and lock the tubes into place in racks with serrated holes allowing for single-handed opening and closing. Conical bottoms allow for more complete sample retrieval while our superior O-ring design forms a positive seal against the rim of the screw-cap to guard against leakage. These popular conical and free-standing tubes are available in 0.5ml, 1.5ml, and 2.0ml sizes. Available in clear or in an amber color for light-sensitive applications, these tubes are free of RNase, DNase, and endotoxins. 

Screw-caps: O-ring & plug closures

MBP’s special O-ring screw cap is manufactured from autoclavable polyethylene and polypropylene which forms a positive seal against the rim of the tube to ensure against leakage even under the most demanding conditions. Available in a variety of colors, these screw caps adapt to both your everyday and critical scientific experiments. MBP’s plug caps are ideal for routine laboratory analysis and procedures. The low-density polyethylene plug caps are the perfect match to MBP’s capless microcentrifuge tubes. Available in a size that accommodates both 1.5ml and 2.0ml capless tubes, they are perfect for collecting fractions and mixing reagents. These plug closures are not autoclavable.

The amber advantage

AMBER tubes are available in all sizes both Conical and Free Standing, so when you are working with light sensitive applications you can rely on HLT branded Amber tubes to block out that destructive light keeping your sensitive samples protected. 

Minitube microtiter tube systems

MBP’s line of MicroTiter tubes supplies you with benefits other companies can’t match. Each MicroTiter tube system is available pre-racked in an 8x12 format and can be autoclaved, sealed, and frozen for storage. These tubes offer additional volume capacity for sample dilution and/or mixing prior to procedures such as HTLV-III testing, RIA, EIA, PCR, pharmaceutical quality control, blood bank sample freezer storage, or transport of specimens and reagents. With frosted writing areas on each tube, identification and organization are simplified. Available in bulk packaging, or in a robotic workstationcompatible tip rack, these microtiter tubes can be easily integrated into experiments on your Beckman, Tecan, Tomtec or other automated liquid handling workstations. A low density Polyethylene Cap strip is used to seal these tubes. They can be used with rows of tubes or easily cut apart for individual samples. They are available non-sterilized or pre-sterilized as the material will not withstand autoclaving. Only MBP can bring such innovation to your ever-evolving technical needs. 

Specialty microcentrifuge tubes

Our small-volume, specialty, microcentrifuge tubes are dedicated for lesser sample sizes, and offer a unique combination of quality and features that make this the small-volume-protocol tube of choice. MBP’s 0.4ml and 0.25ml size microcentrifuge tubes have an attached snap-seal closure that provides a leak-tight seal. Specially formulated translucent low-density polyethylene provides an excellent view of sample contents, and makes the 0.4ml tube material much softer and easier to cut for pellet removal. These tubes feature a nonwettable surface and smooth interior to aid in complete sample removal and recovery. Choose MBP for all of your specialty experiment needs. 

Capless, graduated microcentrifuge tubes

MBP’s capless clear graduated microcentrifuge tubes offer the same superior quality, crystal-clear polypropylene as our microtubes with caps, but these offer the versatility for those experiments where caps are not needed and storage is not required. The tubes’ ultra-smooth bottoms allow for 100% visibility and full sample recovery. All three sizes (0.5ml, 1.5ml, and 2.0ml) come with graduations and a frosted, side-area for writing.
