What is the accuracy of Hamilton syringes?
Hamilton syringes are manufactured to be accurate within ±1% of nominal volume, and with precision within 1%, measured at 80% of total scale volume. The design of our barrel and plunger dimensions assures high levels of accuracy and precision. The Hamilton Company Quality System is ISO 9001-2000 certified.
Can I use Hamilton syringes on humans?
Hamilton syringes are not manufactured for human use. To discuss potential off label uses for Hamilton syringes please contact Technical Support.
Do I need slots on my TLL syringe?
The slots, on a TLL syringe with slots, are a carryover from instrument syringes dating back to the 1960's. Older instruments used to have pegs that fit into the slots to hold the syringe in place, but today very few instruments or applications require the TLL syringes with slots. There is no difference in performance between the syringes, with or without slots, and they can even be used interchangeably.
Is the volume of fluid in the needle part of the total volume of the dispensed fluid?
When using a Hamilton syringe, the volume in the needle (called dead volume) is considered constant and the volume being dispensed is absolute. The same dead volume is maintained throughout aspirate and dispense stages.
Are the plungers for the 700 series MICROLITER syringes interchangeable?
No, they are not! Each plunger is fitted to a specific syringe barrel. Be very careful to keep each plunger with its original syringe in order to maximize syringe performance.
What are the most versatile syringes made by Hamilton?
GASTIGHT syringes are the most versatile syringes. The plungers are replaceable if it is bent. Any of the Metal hub, Kel-F or Removable needle allow for the replacement of needle if they become bent or plugged.
How can I sterilize my syringe?
- Chemical sterilization is the preferred method for all Hamilton products. Autoclaving syringes should only be used as last resort and only where specifically stated.
- Syringe sterilization is a complicated issue. Not all syringes can be autoclaved. Click here for a list of Hamilton products and their preferred sterilization method.
How do I select the correct needle?
- You will need to answer the following questions:
1. What is your application?
Chromatography, Life Science, etc and what instrument are you using?
2. Do you already have a syringe, if so what kind?
What volume and what termination? Cemented, RN, TLL etc
3. What gauge do you think you need?
We make 10 gauge all the way down to 33 gauge.
4. What length do you need?
- Our standard length is 2 inches and all other lengths are considered a custom product
- Hamilton makes thousands of different needles, which is why we need as much information from the enduser as possible.
Is the digital syringe automated or manual?
The Digital Syringe is a manual syringe with a digital display which allows you to clearly see the aspirated volume. The Digital Syringe is not automated, it will not dispense with the touch of a button. It operates like a typical syringe, but there is no guessing as to the volume being aspirated or dispensed.
What does the "s" mean in a 22s or 26s gauge needle?
The "s" represents a smaller inner diameter for the needle and a thicker needle wall for better durability. For example, a 26 gauge needle has an outer diameter of 0.46mm and an inner diameter of 0.26mm while the 26s gauge needle has an outer diameter of 0.47mm and an inner diameter of 0.13mm. The 26s has half the inner diameter of the 26 gauge needle. The difference in the wall thickness also nearly doubled with 26s gauge having a thickness of 0.18mm while the 26 gauge is only 0.10mm.
What rheostat is recommended to work with the syringe cleaner?
The syringe cleaner requires a Variable Autotransformer and we recommended finding the rheostat at an electronics supply house like Newark Electronics. For example: Newark Electronics - P/N 66F3591 or Tenma P/N 72-110
