Frequently Asked Questions
1. Why should I use NORM-JECT® syringes for chromatography?
NORM-JECT® syringes are two-part (all-plastic) and contain no silicone oil or rubber. This makes them ideal for HPLC and GC sample preparation, as there are no lubricants to interfere with your analytical results.
2. What is the difference between Luer and Luer-Lock?
Luer is a "push-on" friction fit, while Luer-Lock features a threaded collar that allows the needle or filter to be screwed on securely, preventing it from blowing off under high pressure.
3. Are HSW syringes available in sterile and non-sterile versions?
Yes, HSW provides sterile-wrapped syringes for medical and biological work, as well as non-sterile bulk packs specifically designed for routine laboratory and industrial tasks.
4. Can Henke-Sass, Wolf veterinary injectors be autoclaved?
Many of their high-quality veterinary and multi-dose injectors are made from heat-resistant materials like glass and metal, making them suitable for sterilization. Always check the specific model's manual for temperature limits.
