Lab Products

Laboratory consumables and accessory equipment play a vital role in ensuring the quality and accuracy of results. From pipettes and test tubes to filters and culture media, each of these consumable laboratory supplies acts as an integral part of research and diagnostic processes. Additionally, laboratory equipment accessories like probes, spectrophotometer cells, and cuvettes complement the precision and efficiency of advanced instruments.

Consumable Laboratory Equipment

Laboratory consumables include tools and equipment used in diagnostic processes, medical research, and clinical and scientific tests. Here are a few examples of disposable items in the laboratory and their uses:

Safety Lancet

The safety lancet is one of the most important disposable laboratory items, playing a key role in the blood sampling process. This product, categorized as a laboratory consumable, provides safe and less painful sampling due to its special design. The types of this product include:

• Automatic Safety Lancet (Autolancet): The automatic safety lancet, also known as an autolancet, is one of the most widely used low-cost laboratory equipment for blood sampling. This product is designed so that after a single use, the needle retracts, preventing reuse. Autolancets can typically be used without the need for other medical devices, making them an ideal choice for medical centers. Important applications of this product include blood typing, genetic tests, and infant sampling.
• Glucometry Safety Lancet (Non-Automatic): Glucometry lancets are another example of consumable laboratory equipment primarily used for blood glucose testing. These products, classified as disposable laboratory items, consist of a four-pronged or two-pronged needle and a special lancing device (pen). The main difference between this type of lancet and the automatic model is the need for a specific device (lancing pen) for use. This type of laboratory consumable is mostly used by diabetic patients who need daily blood glucose monitoring.
• Standard Safety Lancet: This category of medical and research consumables includes simpler lancets, primarily made of stainless steel. Although these low-cost laboratory tools have a simpler design than automatic models, they still meet the necessary standards for safe sampling. Book lancets, also known as two-sided lancets, and standard or four-sided lancets, are among these products. These disposable laboratory items are mostly used when simple and quick sampling is required.

Pen Needle

The pen needle is an essential consumable item in laboratories and medical centers, playing a significant role in injection processes as a replaceable laboratory accessory. This small but vital device is considered everyday laboratory equipment, and alongside other laboratory instrument accessories, it has various applications. Due to its specific design, this device allows for accurate and less painful injections. Pen needles are usually produced as sterile and single-use items and are among the laboratory consumables that must be regularly replaced. A pen needle consists of several main parts:

• Needle Tip: The part that penetrates the skin, usually very thin and sharp to minimize pain.
• Plastic Body: The part that attaches to the injection pen, allowing for easy handling.
• Protective Cap: To maintain sterility and safety before and after use.

Pen needles, like other medical needles, are measured by the Gauge (G) system, which indicates the needle’s diameter. The larger the G number, the thinner the needle. Common pen needle sizes, as one of the laboratory instrument accessories, include G30 (0.3 mm), G31 (0.25 mm), and G29 (0.33 mm). The length of pen needles also typically varies between 4 to 8 mm, chosen depending on the type of use and the patient’s condition. When selecting a pen needle as a consumable item in the laboratory, various factors such as needle diameter, needle length, manufacturing technology, etc., should be considered.

Guthrie Card

The Guthrie card is an essential laboratory aid in the process of newborn screening, playing a key role in the early diagnosis of congenital metabolic disorders. This special paper, packed in plastic laboratory containers, is part of ready-to-use kits for collecting blood samples from the heel of newborns. The Guthrie card was first introduced in the 1960s by Dr. Robert Guthrie for the diagnosis of Phenylketonuria (PKU), revolutionizing newborn screening. This tool, as one of the laboratory replacement parts for traditional blood sampling methods, allows for the collection, transfer, and storage of samples in a standardized manner.

In the screening process, which typically takes place between 3 to 5 days after birth, after disinfecting the newborn’s heel with an alcohol pad (which is part of the ready-to-use kits), a small scratch is made using a sterile lancet, and a few drops of blood are collected on the Guthrie card. This sample is then sent to the laboratory after drying. The Guthrie card, as an advanced laboratory aid, enables the diagnosis of numerous metabolic diseases, including congenital hypothyroidism, phenylketonuria (PKU), galactosemia, maple syrup urine disease (MSUD), congenital adrenal hyperplasia, and G6PD enzyme deficiency (favism).
