Heathrow Scientific® Lead Rings

Heathrow Scientific® Lead Rings are designed to stabilize glassware and lab vessels securely on the benchtop or in water baths. These vinyl-coated lead rings offer a flexible and protective solution for preventing tipping or movement of flasks, beakers, and cylinders during procedures.

The durable vinyl coating protects both your labware and benchtop from scratches, marks, or damage, while the C-shape design option allows for slight manual adjustment to accommodate a range of vessel sizes.

Ideal for labs using water baths or uneven surfaces, these stabilizing rings improve safety and efficiency during experiments. Sold in vibrant blue, they offer easy visibility in busy workspaces.

Key Features

• Stabilizes labware on benchtops or in water baths
• Vinyl-coated lead won’t scratch glassware or lab surfaces
• Ideal for use with flasks, beakers, and graduated cylinders
• Durable, reusable, and easy to clean
• Color: Blue for visibility and organization

Azure ChemiWriter ECL Pen

Chemiluminescent pen for blot annotation

The Azure ChemiWriter ECL Western blot annotation pen is a chemiluminescent marker that enables you to write or draw on your transfer membranes, resulting in a chemiluminescent signal on your markings once substrate is added. Contains a reagent that reacts with HRP substrates to produce chemiluminescence and also a blue dye to allow you to see markings as you write on the Western blot.

Use for tracing visible protein ladders or making identifying marks on your Western blots. Pen has two tips on each end: one fine-tipped for thin markings and one thicker for depositing more of the reagent.

Quantity: 1 pen

Features

Enables you to write or draw on your transfer membranes. A chemiluminescent signal will be detectable from your markings once chemiluminescent substrate is added.

• Use for tracing visible protein ladders or making identifying marks on your blots. Pen has two tips on each end: one fine-tipped for thin markings and one thicker for depositing more of the reagent.
• There are two heads to the pen, a fine point tip and a thicker chisel point tip.
• We recommend using the fine point tip to annotate the blot and mark protein ladders for detection.
• The chisel point of the pen can be used to deposit an increased amount of reagent on the blot for more intense signal.
• For best results we recommend annotating your blot after transfer and before starting your Western blotting protocol.
• Once annotated, the blot may be stored dry or wet, refrigerated or at room temperature.
• Storage: pen should be stored tightly closed at room temperature. ChemiWriter ECL reagent and blue ink markings on the blot are stable for at least three months.

RWD Osmotic Pumps

With competitive prices, RWD miniature infusion pumps are designed for precise and continuous long-term dosing in mice and rats, durations for up to 6 weeks, which relieves researchers who are burdened by multiple injections.

Osmotic Pumps can be implanted subcutaneously or intraperitoneally for systemic administration or connected to a catheter to provide targeted delivery for blood vessels, brain, spinal cord, lung, liver, or other specific areas of infusion.

The Osmotic Pump consists of a robust semi-permeable membrane that allows animals’ fluids to pass through. Built-in high-pressure salt interlayer absorbs animal fluids, causing them to expand and squeeze the drug storage capsule. The liquid stored in the capsule can be delivered to specific tissue areas continuously and accurately at a constant rate. 
 

The pump can be implanted directly into the peritoneal cavity or the back of the neck to deliver the drug. The pump rate is stable through in-vivo testing.

*Made of biocompatible material to avoid immune rejection after implantation in rats and mice. Each pump is also sterilized by irradiation to ensure no inflammatory reaction in mice and rats.

Applications include cardiovascular disease model, addiction research, emotion-based research, medication research for diabetes and other metabolic diseases, pain, injury, and other therapeutic drug infusions, and cancer drug screening.

• Predictable dosing minimizes experimental variables to ensure reproducible and consistent results.
• Reduces the stress response by continuous administration without frequent animal handling. Ensures experimental results and animal welfare is guaranteed.
• Wide application, easy to operate. Reduces the need for regular injections at night and on weekends.
