Stainless steel is an alloy, which does exactly what its name implies: stains less than ordinary steel (iron). Yes, it can stain, discolor and rust, given the right circumstances.
To make iron stainless, nickel and chromium are added in certain quantities, depending on the purpose it is being used for and the quality required. The more chromium added to the mix, the softer the alloy becomes, something not desirable in a surgical instrument. Given that, quality medical stainless steel alloy is of a very specific, narrowly defined mix.
A further aspect of making steel "stain less" is a repeated process of extracting surface impurities, mainly minerals. And the final high polish of the finished instrument puts a minute protective coating on it, also very important to make the instrument "stain less". Whether the final product is highly polished or matte finished will make no difference in its stainless ability.
Instruments with gold handles means they are made with tungsten carbide.
Tungsten carbide is one of the hardest alloys available and lasts almost two times longer than stainless steel. Tip inlays are either glued or welded into place. For needle holders, tips can be made with a pyramid cross pattern that holds suture needles much more securely.
Compare the extra cost of these instruments with the length of useful wear, and you have a cost effective solution for your instrument requirements.
Scissors with black handles means they are ToughCut®.
ToughCut® scissors feature two unique cutting edges that cut through the toughest tissue with exceptional ease and accuracy. One blade is honed to razor sharpness, and the other is micro-serrated to minimize tissue slippage during cutting.
One of the hardest materials on Earth, ceramic is used in surgical instruments to form edges that last longer than stainless steel and even longer than tungsten carbide. Ceramic also has a high slide capacity which reduces surface tension and results in a much cleaner cut than metal instruments.

For large colonies of mice, RapID Tags® are one of the most efficient and reliable options. Their 2-D matrix barcodes allow for millions of unique IDs, are quick to scan, and integrate seamlessly with lab software. This reduces human error, speeds up workflows, and improves animal welfare—making them ideal for high-throughput studies
To product: RapID Tags®
Yes, RapID Tags are designed for durability, making them suitable for both short-term and long-term research studies.
Our Ear Punchers features a spring-action mechanism that relieves the stress on the researchers wrist and also has a sloped edge for a more precise and less traumatic cut. The often-perfect cut can then easily be collected for genotyping, in the AT7000 also directly collected in a standard vial.
Our most popular Stereotaxic setup for mouse is the Kopf Model 940 with Digital Display Console with a 10-micron (0,01mm) resolution. This frame is typically equipped with the 922 Mouse Non-Rupture earbars and the superior 923-B Mouse Gas Anaesthesia Head Holder, ready for connecting to your gas Anaesthesia Machine.
We can add/omit any accessories to your need.
When making a cut it is easiest to insert the blade at an angle, not straight down. Insert the blade in one side of the matrix at about a 45 degree angle then cut with it. Make the first cut with a blade and leave it in the Brain Matrix. Then take a second blade and make an adjacent cut. Leave this second blade in the Matrix as well. Now you can remove the first blade and cut with it again. Continuing in this “leap frog” method allows for more control over your cuts and limits brain movement while slicing. When using this method, the previously cut slice will stick to the “leaping” blade as you pull it out to make your next cut. This should be removed before making the next cut.
You may also choose to use more than two blades leaving multiple blades in. Some may find it beneficial to place a blade at either end of the desired section, and then make their cuts between the two end blades. Making a cut halfway between the blades, then cutting each half in half, etc. is a very stable way of doing it. Then to remove a slice, pull out the two blades on either side of it. After one slice is removed you only need to pull up one blade at a time to get each additional slice as it should stick to the blade.
Our Stainless Steel Models for coronal cuts are the most popular ones:
We offer expert guidance in selecting the right system based on your species, study design, and lab setup. Whether you need a compact solution for one animal at a time or a high-throughput setup with multiple delivery ports, our team can help you build a configuration that meets your needs. We also provide manuals, training material, and technical service for all our products together with our partners.
All our systems are delivered calibrated and ready for use and normally doesn’t require any recalibration. Lead times vary depending on configuration—contact us for current stock and delivery options.
A syringe pump is a precision instrument used to deliver or withdraw specific volumes of fluid at a controlled rate. It works by moving the syringe plunger using a motorized pusher. This ensures accurate, often pulse-free flow for applications like drug delivery, microdialysis, or infusion into laboratory animals. Models vary in the number of syringes they support, flow rate range, and control options (manual or programmable).
Yes. Syringe pumps like the Univentor U-864 and Legato 270 are ideal for flow chemistry and the 801 for microdialysis. They offer precise, pulse-free flow—crucial for stable reactions and consistent analyte recovery. Dual-syringe and push/pull models enable continuous flow for advanced applications.
No regular calibration is needed. Legato pumps are pre-calibrated by the manufacturer. However, you must enter accurate syringe dimensions in the pump settings to ensure correct volume and flow rate delivery. Always verify syringe compatibility for optimal performance.
Yes, many Legato models offer RS232 and USB connectivity, allowing external control via PC software. This enables programmable sequences, remote start/stop, logging, and integration into automated lab systems.
Legato pumps support syringe sizes from 0.5 μL to 140 mL, depending on the model and rack type. This is controlled via user input, allowing the pump to operate with virtually any syringe that fits within its specs.
The Legato™ series from KD Scientific includes a variety of models such as:
• Legato 100/200 – Basic infuse-only pumps (single/dual syringe)
• Legato 110/210/270 – Infuse/withdraw models with continuous flow
• Legato 180/185 (PicoFlow) – Ultra-low flow pumps for high-precision dosing
• "P" models (e.g., 210P, 270P) – Fully programmable with RS232/USB control.
Each model differs in flow rate range, syringe compatibility, programmability, and number of syringes
Yes. All models (801, 802, 864) are designed for high-precision applications and deliver constant, pulse-free flow using a DC motor with closed-loop speed.
The Univentor 801 is a compact microdialysis syringe pump, optimized for precise, low-noise, pulse-free infusion. It is ideal for in vivo research requiring consistent delivery of small volumes at very low flow rates.
To produkt: Univentor 801
Yes. While it comes preprogrammed for 1.0, 2.5, and 5.0 mL syringes, it can accommodate any syringe with a 60 mm graduation, thanks to adjustable clamping and customizable flow settings.
Yes. With the optional Withdrawal Adaptor, the 864 can perform simultaneous infusion and withdrawal, ideal for microdialysis or bidirectional studies.
