Bullet Blender® Tubes

Eppendorf™ Safe-Lock tubes are 1.5 mL polypropylene microcentrifuge tubes for use in Bullet Blender® Storm (BT24M) and Bullet Blender® 24 Gold (BB24AUP) models.

GATOR™ tubes are 1.5 mL microcentrifuge tubes for use in the Bullet Blender® Gold (BB5EAUP), (BB24AUP), and Bullet Blender® Storm (BT5E), (BT24M), (BT12LT) models. 5 mL GATOR™ tubes are for use in Bullet Blender® 5E Pro (BT5E) and 5E Gold (BB5EAUP) models. The caps stay tightly sealed even under vigorous agitation. The PCR is clean and free of RNase and DNase.

RINO® screw-cap tubes are 1.5 mL microcentrifuge tubes for use in Bullet Blender® Storm (BT24M) and Bullet Blender® 24 Gold (BB24AUP) models. They are made of a special extra-tough polypropylene material, ideal for vigorous homogenization. They are also transparent, allowing you to visualize your samples! Sterile & RNase free.

*Use only with RINO® lid gasket. RINO® tubes should not be centrifuged at speeds higher than 14,000 RCF with beads inside, as the weight of the beads can cause the tubes to leak.

HIPPO™ skirted, self-standing, 50 mL tubes are ideal for use in our 50 mL Bullet Blender® models, including the 50 Gold+ (BB50AUP), and 50 DX (BB50DXP) models. HIPPO™ Tubes can hold substantial amounts and are exceptionally durable. Caps remain tightly sealed on the tubes, even after vigorous agitation. DNAse, RNAse, and pyrogen free.

Green Reagent Reservoirs

Innovative Design Saves Space and Reduces Plastic Waste

The "Green" Reagent Reservoirs incorporate several innovative design features that reduce plastic waste, save storage space, and enhance performance. This reagent reservoir system consists of disposable, clear polystyrene inserts that fit within a rigid base. Because the skirt on the inserts has been eliminated, this significantly reduces the amount of plastic waste that is experienced when using standard one-piece reagent reservoirs.

• Innovative design that reduces plastic waste and saves space
• Saves 75% in storage space
• Easy-to-see, bold, black Vol graduations eliminate costly overpours
• Pour-spout corners provide easy, spill-free pouring
• Unique trough within a trough design for complete sample retrieval
• 2nd reservoir can act as a lid to prevent evaporation and contamination

Heathrow Scientific® Multi-Channel Reagent Reservoirs

Heathrow Scientific® Multi-Channel Reagent Reservoirs offer a versatile and contamination-reducing solution for multi-channel pipetting workflows. Featuring a dual-compartment design, this reservoir includes a single 50 mL basin on one side and twelve individual 5 mL slotted basins on the other—perfect for handling multiple reagents with minimal waste.

Each slotted well is numerically imprinted for easy sample identification, while angled basin walls guide pipette tips to the center, helping reduce cross-contamination and reagent loss. The included snap-on cover protects contents from evaporation and contamination during short-term storage or processing.

Made from white polypropylene, this disposable yet autoclavable reservoir is ideal for sterile environments. Sold in packs of 25, it’s a practical consumable for research, clinical, and industrial laboratories.

Key Features

• Dual compartments:
• One 50 mL basin

Krystal™ 2000 Plates

The premium polycarbonate Krystal™ 2000 plates have been optimized for luminescence and fluorescence assays. A proprietary manufacturing process provides for clear, individual wells in an opaque matrix. The special design of the plate eliminates well-to-well light cross-talk, improving the accuracy and precision of photometric readings.

Krystal™ 2000 plates are supplied in a 96 x 350 μL well format. Clear wells allow for measurements to be performed with both top and bottom reading instruments. The white matrix provides for maximum reflectivity, allowing high sensitivity luminescence assays. The black matrix absorbs light to minimize background interference in fluorometric assays. Plates are available as tissue culture-treated. The tissue culture plates are supplied in packages of 100.

• Unmatched accuracy and repeatability for fluorescence and luminescence assays

• Unique, individual clear well design eliminates cross talk, and allows for reading above or below wells

• Sleeved plates with lids are available for use in robotic systems

• 96-well format (350 µl well volume)

• Bar coding available
